Structure of Merit Program
Historic Preservation in Boulder
In the early 1970’s, the Boulder area lost several important buildings to new development. The community
Responded with a grassroots effort aimed at legally protecting the city’s many historic places. In 1974, the Boulder
Historic Preservation Ordinance was passed. With the City Council adoption of this code, Boulder became one of
the first cities in Colorado with the authority to designate and prevent the demolition or destruction of historic,
architectural, and cultural resources considered valuable to the community. Today, more than 30 communities in
Colorado have similar historic preservation ordinances, many of which are based on Boulder’s model.
Historic preservation is about recognizing and protecting something --an older building or neighborhood or a
piece of landscape, for instance-- because of its importance to the community. This might mean saving a building
because it has architectural or educational value, or because it links us to characters or events from the past. It also
means protecting modest, simple buildings along with high-style, elaborate ones. We recognize that many of our
old buildings still have plenty of life left in them; whether they continue to be used the way they were originally
intended or are reused in some new “adaptive” way, there are environmental, economic and social benefits to
preserving them.
Structure of Merit Program
This Structure of Merit program was established in 1988 but has not been active since 1997. The Landmarks
Board approved regulations for the Structure of Merit (SOM) program to recognize non-landmark properties
possessing historical, architectural, or aesthetic merit. The overall goal of this program is to recognize and
encourage the protection, enhancement, and use of such structures.
The Landmarks Board views the SOM listing as a way to increase preservation awareness and encourage
community value for recognized properties. Different from landmark designation, the SOM program is strictly
honorary and is not subject to the same review processes for alterations to designated individual landmarks
or resources within listed historic districts and the procedure for recognition is less regulated than the process
associated with landmark and historic district designation. As resources are listed on either the National Register
or State Register, these properties are automatically added to Boulder’s ongoing listing of SOMs. As additions
are made to the SOM list, the property owners are notified. In 1997 the Landmarks Board slightly revised the
administrative rules for the SOM program intending to ensure consistency between SOM rules and the historic
preservation code’s demolition and relocation review process. Demolition and relocation review is required for
any building fifty years or older and for SOM properties under fifty years of age. This provision was subsequently
changed again in response to owner opposition. SOM properties under fifty years of age no longer are subject to
demolition review.
The following booklet lists the current properties recognized as SOMs. Many of these were chosen for their
relation to a Landmarks Board selected theme. For example, in 1987 the board focused on Goss-Grove Little
Rectangle houses. Other thematic listings include those of the terrace form (1989) and homes designed by
architect Charles Haertling (1997).
There are four ways in which a SOM is recognized:
1. All structures officially designated by state or federal agencies are automatically on the list since the
ordinance requires their inclusion. Thus structures listed on the Colorado State Register of Historic
Properties (SR) and the National Register (NR) will be listed.
2. As surveys of Boulder are completed, neighborhood by neighborhood, the Landmarks Board will review
survey results and consider appropriate SOM designations.
3. The Landmarks Board will consider neighborhoods in which few individual structures have been
landmarked, yet contain structures which merit designation.
4. Types of structures important to the development of Boulder such as churches, schools and terraces, may
also be considered for designation.
The Process for Recognition of a Structure of Merit:
1. Application: An application for recognition may be submitted by either the property owner or the
Landmarks Board. (When the Landmarks Board proposes to consider other structures for recognition,
immediate notification to property owner is required.)
2. Procedure: The City Manager shall refer to the Landmarks Board any application or resolution for the
recognition of a structure of merit.
3. Criteria or Recognition: The Landmarks Board may recognize a structure as a structure of merit if the
structure is of historical, architectural, or aesthetic merit.
4. Record of Historic Structures: The Landmarks Board shall maintain a record of historic structures in
the city that have been officially designated by agencies of the state or federal government and shall add
structures as recognized.
5. Recognition by Landmarks Board: The Landmarks Board may authorize such steps as it sees fit to
encourage the protection, enhancement, perpetuation, and use of structures by issuing certificates of
recognition (without limitation) and authorizing plaques to be affixed to the exteriors of recognized
structures.
Although dormant for some time, the SOM program still retains value. The Landmark Board members have
attempted to reinvigorate this program over the years, but unfortunately this has yet to happen. However, it is
the hope of the 2013 Landmarks Board that this booklet will be the first step in the right direction. Since SOM
properties are not subject to the same level of review as designated resources, this program will serve as a less
process-driven introduction to the Boulder historic preservation system for property owners. While SOM do not
receive as much protection as landmarks or buildings within historic districts, the recognition potentially can lead
to not only increased owner pride but it will also serve as a list of potential historical sites for local preservation
advocates, the Landmarks Board and City Staff.

A Guide to
The City of Boulder’s
Structure of Merit Program
SOM-1
George-Paddock House
845 11th Street
The George-Paddock House was built c. 1909 by Dr.
Russell George to meticulous specifications, including
solid brick walls, inside and out. Dr. George moved to
Boulder in 1903 to head the Geology Department
of the University of Colorado and became the State
Geologist from 1907 to the mid 1920s. In 1939 A.
A. Paddock purchased the home from the Georges.
Paddock was editor and publisher of the Boulder Daily
Camera, a newspaper founded in 1891 by Paddock’s
father, L.C. Paddock, and grandfather, Valentine Butsch.
The house is a three-story, foursquare cottage with
an unusual L-shaped porch. The building is a type
commonly associates with substantial and prosperous
residential architecture.
SOM-2
McNutt-Downing House
983 14th Street
The McNutt-Downing House was built in 1892 by
David W. McNutt, and is significant as being one of the
earliest and most substantial homes on University Hill.
David McNutt was one of Boulder’s earliest residents
who moved to Colorado for health reasons. He owned
various rental properties in Boulder until 1910, when
he traded his home on 14th Street for a ranch near
Fort Morgan, where he lived until his death in 1912.
The property changed hands several times, until it
was purchased by Roderick L. Downing in 1934. The
historical significance of this house for Boulderites is
most closely associated with Downing, who is best
known as “Father of the Denver-Boulder Turnpike.” The
McNutt-Downing House is a two-and-one half story
brick structure with an unusual combination of hip and
gable roofs. It is a vernacular building with a variety of
detailing, including a round arch window, unusual two-
story frame porch, a side bay, and brick string courses.
SOM-3
Coulson-Noxon House
907 7th Street
The stately brick Coulson-Noxon House was built
by Dr. David E. Coulson between 1900 and 1904. Dr.
and Mrs. Caul son came to Boulder from Monmouth,
Illinois for Dr. Coulson’s health. He continued his
dental practice while Mrs. Coulson was principal
of Central School and later taught at University Hill
Junior High. Victor Noxon purchased the house from
the Coulson’s in 1914. Noxon was an 1886 graduate
of the University Of Colorado School Of Engineering
and after graduation, was a newspaper publisher and
editor in Idaho Springs. After moving back to Boulder
so his children could attend CU, he started the Boulder
County Farmer and Miner, and he and Lucius Paddock,
publisher of the Daily Camera, carried on a spirited
feud through their respective editorial pages. The
Coulson-Noxon House has more recently become
significant as the home of Astronaut Scott Carpenter,
son of Noxon’s daughter Florence. Carpenter was the
second man to orbit the earth as part of the Mercury
program in a space capsule he named Aurora 7, in
reference to his boyhood home. Essentially a brick four
square residence, the Coulson-Noxon House is very
plain, with Queen Anne elements including a corner
tower and matching second floor turret. The original
house had a third floor which burned in the 1920’s, and
the present roof line is considerably altered.
SOM-4
The Castle
977 9th Street
The Castle was built by Boulder brick mason Benjamin
Franklin Gregg in 1905 and 1906. Frank Gregg was
born in Indiana and moved to Boulder in 1873. He
owned and operated the Colorado Cement Factory,
and was a masonry contractor whose work included
the Octagon House at 821 Lincoln Place and the James
P. Maxwell House, in addition to the Castle. The
significance of the Castle lies in its unusual architecture
and as the name suggests, resembles a castle. It was
constructed of Boulder Brick which was hand-chipped
by Gregg’s son Earl. The bricks came from the Boulder
Pressed Brick Company which was located at the
present site of Casey Junior High School. The exterior
walls are two widths of brick with an air space between,
and the interior walls of the main floor and basement
are solid brick. The house is placed at an angle on its
corner lot to allow sunlight into every room during
some part of the day. There are five floor levels, making
this Boulder’s first split level house, and only four of the
rooms are four-sided with right angles.
SOM-5
1915 ½ Goss
The builder of this vernacular cottage is unknown, as is
the exact date of construction. The significance of this
small, simple house is that it is one of the only remaining
‘back lot’ houses. Back lot houses were built as a result
of overcrowding in the Goss-Grove neighborhood,
since housing was generally unavailable to early black
residents in other areas of Boulder. This back lot is a
rectangular frame box with hip roof that extends from
the front of the house to cover the porch. The roof has
simple post supports and there are several steps from
grade to porch. The entry is centered with windows
on either side.
SOM-6
1935 ½ Goss
The builder and exact date of construction of this ver-
nacular structure are unknown. The significance of this
small frame house is that it is one of Boulder’s only
remaining back lot houses. Although it has been sub-
stantially altered over the years, its size has remained
unchanged, making it recognizable as a back lot house.
Back lot houses were built as a result of overcrowding
in the Goss-Grove neighborhood, since housing was
generally unavailable to early black residents in other
areas of Boulder.
SOM-7
Martha Hall House
2102 Goss
The builders of this vernacular frame house, as well
as the exact date of construction are unknown. Its
significance lies in the fact that it was at one time the
home of long-time Boulder residents, James and Mar-
tha Hall. Mr. Hall was a former slave and Civil War vet-
eran. The Halls moved to Boulder in 1876 and were
living in this house by 1896. This simple hip roofed
frame house is typical of the residences built near the
turn of the century in the area referred to as the “little
rectangle” bounded by Canyon Boulevard, 19th Street,
Goss Street and 23rd Street. This area was home to
the city’s minority groups in the late 19th and early
20th centuries.

Oscar & Mary White House
2202 Goss
The building and exact date of construction of this
vernacular frame house are unknown although it was
probably built before 1898. Its significance lies in the fact
that it was once the home of Oscar and Mary White.
Mr. White was a former slave and civil war veteran. The
Whites were charter members of the Allen Chapel
of the African Methodist Episcopal Church which was
the focal point of Boulder’s early black community. This
simple hip roofed house has been changed somewhat
over time, but remains an example of Boulder’s early
minority housing in the “little rectangle” area of the
Goss-Grove neighborhood.
SOM-10
James Sackett House
2250 Goss
The exact date of construction and building of this
simple vernacular frame house are unknown although
it was probably built before 1896. Its significance is
twofold: It was the home of James Sackett who was
a fruit grower. The Goss-Grove Sackett who was a
fruit grower. Sackett who was a fruit grower. The Goss-
Grove neighborhood was first settled as an agricultural
area, filled with orchards, and this house is one of the
few that can be directly linked to this past. In addition,
it is a virtually unaltered hall and parlor house, a folk
building type transplanted from the rural south by early
black settlers.
SOM-11
Henry Drumm House
1638 Grove
This masonry residence was built in the 1890s and
is located in what is now known as the Goss-Grove
neighborhood. The house belonged to Henry and Stella
Drumm at the turn of the century, and is significant
because of Henry Drumm. He was a prominent citizen,
an 1878 graduate of the State Preparatory School, and
a member of CU’s first graduating class in 1878. He was
a lawyer, Justice of the Peace, City Council member, and
most importantly, a cartographer. Drumm produced
maps which are still being used today. The Drumm
House is a vernacular structure with Queen Anne
detailing, a common type in Boulder; however, there
are very few such structures that remain unaltered, and
is among the small, simple houses of Goss-Grove, this
larger and more substantial house is significant and
intact.
SOM-12
1728 Grove
The builder of this vernacular cottage is unknown, as is
the exact date of construction although it was probably
built in the 1890s. Although similar masonry structures
were common in Boulder, the significance of 1728
Grove lies in the unusual amount of unaltered detailing
applied to this simple Goss-Grove neighborhood
house. A one and one half story hip roofed cottage,
the decorative ornamentation includes a columned
porch, patterned shingles in gable ends, and patterned
brickwork.
SOM-13
Charles B. Anderson House
1902 Grove
The brick house at 1902 Grove Street was built by
Charles B. Anderson in the 1890s. The Anderson
House is one of the most significant in the Goss-
Grove neighborhood through its association with
Charles B. Anderson. Anderson moved to Boulder in
1875 and was a prominent Boulder contractor who
worked on the Highland School, Ryssby Church, and
many residences and office buildings in Boulder and
other Colorado towns. The Anderson Family lived in a
log cabin on the site of 1902 Grove Street before the
present house was constructed. Anderson was active
in recruiting Swedish immigrants to settle in Boulder
and he was responsible for shaping patterns of growth
and construction in the Goss-Grove neighborhood.
The Anderson House is a simple one-story brick house
of vernacular style. It has a cross gable with open porch,
supported by large, turned wood spindle posts. Some
of Anderson’s orchard and some outbuildings are
still intact. These elements make the site a significant
remnant of Boulder’s pioneer heritage.
SOM-14
2141 Grove Street
The builder and date of construction of this Goss-Grove
neighborhood house are unknown. The significance of
this small, one-story residence is that it is one of the
few remaining examples of a hall-and-parlor folk house,
a building type that Boulder’s earliest Black residents
transplanted from the rural south when they moved
west. The form of hall-and-parlor houses is a simple
frame box with side gable roof or relatively steep pitch.
This roof breaks to one of shallower pitch that covers
a simple porch that extends across the front of the
house. The porch is usually one step above grade, and
the roof is supported by simple posts.
SOM-15
Arnett-Fullen House
646 Pearl Street
City of Boulder Landmark No. 56
The Arnett-Fuller house represents the work of
Boulder architect, George E. King. At the time of
its construction, the house was considered one of
the most architecturally beautiful houses in the city.
Willamette Arnett, son of Boulder pioneer, Anthony
Arnett, built the house, intending it as a showplace.
In 1914, Mrs. Hiram Fullen, widow of the successful
Boulder gold miner, paid $17,500 for the house. On
November 17, 1993, the house was purchased by
Historic Boulder in public auction and is currently a
private residence. In 2007, the owners restored the
tower to its original multicolored slate covering which
matched pieces found in the garden and the style
found in photographs from the turn of the century. The
ornate detail, mansard tower and gabled roof make it
an unusually prominent structure in the district and
the house remains a fine example of Boulder’s early
residential construction, having maintained its integrity
of setting and design.

Lytle House
2016 Walnut
City of Boulder Landmark No. 61
The Lytle House was built in 1881 by George and Mary
Lytle. Mr. Lytle was a miner before settling in Boulder,
and had mined in British Columbia and in Gilpin County.
The significance of this house lies in its association with
George Lytle, an important figure in Boulder County
history as one of the original owners of the Caribou
Mine. While the stories regarding the discovery of
the Caribou Mine are varied, they all agree that Sam
Conger, William Martin, and George Lytle uncovered
one of the richest silver lodes in Boulder County. Mary
Lytle had moved to Colorado from Indiana in 1862
after the death of her first husband. She worked at a
variety of jobs, including cook, nurse, and salesperson
for a sewing machine agency. She married George Lytle
in 1872 and they lived in Nederland, Colorado until
1880, during which time George Lytle and John Pickel
owned and operated a general store. In 1880, Lytle
sold his mining and business interests and then moved
to Boulder. The Lytle House is a brick Italianate hipped
cottage and is one of the oldest cottage subtypes The
Lytle’s build an L-plan variation, with curved veranda,
and the wide eaves with brackets that are characteristic
of the style.
SOM-17
Werley House
1813 Pine Street
City of Boulder Landmark No. 60
This house was built between 1884 and 1892 by Peter
J. Werley. Werley came to Colorado in 1868 and spent
many years mining in Leadville and Caribou. He came
to Boulder in 1883, where he became the owner of
a saloon and was involved in the investment business.
The house is significant for its architecture, particularly
its unusual reverse Palladian windows and detailing.
SOM-18
Butsch-Paddock House
1105 Spruce Street
The Butsch-Paddock House was built in 1894 by
Valentine Butsch. This house is significant because of
its association with two owners’ who together began
Boulder’s daily newspaper which is still being published
almost a century later. Butsch moved to Boulder from
Indianapolis, Indiana in 1878. In April of 1892, Butsch and
his son-in-law, Lucius Carver Paddock, purchased the
Boulder Camera, a weekly newspaper which they soon
changed to a daily. After Butsch’s death, Paddock and his
family moved into his house on Spruce Street. Paddock
came to Colorado with his family in 1878 when he
was 18. He worked in his father’s mine, the Mountain
Lion, in Magnolia. He later taught school, and worked
on newspapers in Boulder, Aspen, and Leadville until
purchasing the Boulder Camera with Butsch. Paddock
served as editor of the Boulder Daily Camera for 49
years, becoming well known throughout the state for
his high quality editorials. The Butsch-Paddock House is
a three-story brick hipped cottage with stone base. The
front facade features a round arch window with stained
glass transom, and stone and brick arched lintel.
SOM-19
NCAR
1850 Table Mesa Drive
The Mesa Laboratory of the National Center for
Atmospheric Research was designed by internationally-
renowned architect, I.M. Pei. It was constructed between
1964 and 1968 of textured concrete made from a
special aggregate of local red sandstone. The intent
of the design was to fit the building into the natural
setting of mesa grasses with the flatirons as a back drop.
I.M. Pei was greatly influenced by Mesa Verde’s Anasazi
ruins, and many similarities can be seen between the
towers, keyhole windows, and kivas of Mesa Verde and
the architecture of NCAR. The basic conflict between
the inspiration of Mesa Verde and the resulting
architectural expression of NCAR has made the
building most significant to Boulder. While Mesa Verde
is sheltered by, and part of, the surrounding cliffs,
NCAR stands as a monolith on Walter Orr Roberts
Mesa, and as such, has become one of Boulder’s most
important and visible landmarks. NCAR also has
exceptional significance because it is an important
public building of one of the Twentieth Century’s most
acclaimed architects.
SOM-20
Bernard Houses
1602-1620 Walnut
The Bernard Houses, a series of two-story vernacular
cottages, were built in about1902 by J.J. Bernard. The site
on which the houses are built was purchased from the
federal government by Daniel Pound in 1865. Pound at
one time owned most of what is now Boulder’s central
business district. J.J. Bernard moved to Boulder in the
early 1900’s and owned a garage on Pearl Street, as
well as a construction company. He built the houses as
single family dwellings, and sold the property in 1910.
Although the property changed hands several times in
the following ten years, the lots remained a single tract
until 1921. In 1921, Frank Madden, a Boulder contrac-
tor, purchased the tract, divided it and sold the houses
to individual owners. For many years the houses were
occupied by single families; however, in later years they
were converted to rooming houses and apartments,
reflecting the change in housing patterns of the
areas peripheral to downtown Boulder. In 1974 War-
ren Rovetch purchased the properties and converted
them into an apartment complex. The renovation plans
proposed changing the interior and exterior of the four
houses as little as possible. An exception to this was the
restoration of porches, balconies and other details, to
create an appearance nearly like the original. The back
yards to the south of the houses were combined into
a park-like open space for the common use of all the
tenants. The significance of the Bernard Houses is the
fact that five similar and identical houses combine to
create a unique and charming block. A sensitive ren-
ovation has allowed a housing use, appropriate to the
downtown, to be continued, while preserving the his-
toric character of most of an entire block.

Leech House
575 Arapahoe
The elaborate brick house was built in 1880 by Millard
Leech. It is significant because it is an example of an
architectural style that was not common in Boulder, and
because of its association with Millard Leech. Before
coming to Boulder, Mr. Leech was a detective for the
Union Pacific Railroad. He was later engaged in mining
on Left Hand Creek and at Magnolia for several years.
After years of effort, he was finally able to build “the
Switzerland Trail,” the railroad connecting the cities of
Boulder and Ward. Leech built his house shortly after he
came to Boulder. This two story example of the Second
Empire style is unusual in Boulder for two reasons.
First, there were relatively few residences of this style
constructed, and second, the elaborate detailing makes
this house appear as a miniaturized version of the more
familiar extravagant Second Empire mansions. Features
which characterize this house are a shingled mansard
roof, cornice with brackets and dentals, and beaded
glass squares bordering windows. An original tower
over the entrance has been removed, but otherwise
the building has been changed little.
SOM-22
Clemens House
3345 Broadway
The stone house at 3345 Broadway was built in
1894 by Clara Clemens. The land on which the house
was constructed was purchased from the Federal
Government by Fredrick Squire and Jonathon Tourtellot
in 1870. The land was held by a series of owners, until
James P. Maxwell and George S. Oliver sold it to the
Clemens family in 1888. The Clemens family moved to
a ranch house near Golden, Colorado from Missouri
in 1875, then tried farming near Erie. After two years
of drought and grasshoppers, the Clemens moved to
Jamestown where Clara’s father became involved in
mining. Clara graduated from East Denver High School
in Denver High School in 1887, and taught school
in various locations, including Mapleton and Central
Schools in Boulder. From 1891 to 1895 she was principal
of Whittier School. It was considered most unusual for
a single woman to construct a house, and Clara lived
in her stone house with her mother until she married
in 1913 and moved from Boulder. She entertained her
cousin Samue1 Clemens, better known as Mark Twain,
in this house when he came to visit.
Constructed of local red hill sandstone, the building
is a plain two story rectangular volume with a hipped
roof, and stone sills and lintels. Aside from an addition
at the rear, the house remains almost unchanged, and
is an excellent example of a simple vernacular building
constructed of local materials.
SOM-23
Ruth Cave Flowers House
2019 Goss
City of Boulder Landmark No. 63
This building associated with Dr. Ruth Cave Flowers,
the first black graduate of the University of Colorado,
and is significant for being part of “the little rectangle.”
This area was the center of Boulder’s black community
in the first half of the 20th century. By the 1950s,
the “rectangle” was bi-racial, with a large Hispanic
population. Thus, for at least 50 years, the area remained
the center of the city’s minority population.
Octagon House
821 Lincoln
SOM-24
Known for its very unusual architecture and for its
association with builder Benjamin Franklin Gregg, the
Octagon House was built in 1907 for Oliver and Mary
DeMotte by Boulder brick mason Benjamin Franklin
Gregg. Gregg was born in Indiana and moved to
Boulder in 1873. He owned and operated of Boulder’s
most prominent masonry contractors. His work
included the Castle, the James P. Maxwell House, and
this house. This is an example of the very rare Octagon
Style popularized by Orson S. Fowler in his book The
Octagon House, a Home for All, published in 1849.
Fowler maintained that the octagon shape enclosed
more floor space per linear foot of exterior wall than
more common squares or rectangles. His enthusiasm
was not widely shared since only a few thousand
were built, generally from 1850 to 1870. Only several
hundred survive today, with most examples located in
the east and Midwest, so Boulder’s Octagon House
is truly unique. Although the detailing of many earlier
Octagon Houses is Greek Revival, Gothic Revival,
or Italianate, Frank Gregg’s brick octagon house is
relatively plain with a hipped roof, segmental arched
windows, chiseled brick trim, and a large semi circular
stone arch.

Soule-Coates House
1123 Spruce
City of Boulder Landmark No. 118
The Soule-Coates House contributes architectural
variety to the downtown historic district as an excellent
example of the Colonial Revival Style and is significant
for its successful adaptive rehabilitation from a
residence into office space. The house is one of the
earlier remaining residences in the original Boulder
Township. The Soule-Coates House is associated with
significant persons, including Boulder pioneer Anthony
Arnett’s daughter and Edwin L. Coates, Boulder
government official, businessman and Democratic
Party leader.
SOM-26
711 Walnut
This house was built in 1880 or 1882, probably by a
miner, since most of the other houses on the block
belonged to miners. A very simple two-story front
gable residence made of stone, the first floor is at grade
and an open porch covers the entry patio. The window
and door openings are simple vertical rectangles
with stone lintels and sills. The stonework is finely-
executed random ashlars with convex mortar joints.
There have been few changes made over the years,
the most noticeable of which is a frame dormer. This
stone building is significant because it is one of the few
remaining downtown residential buildings dating to the
early days of the settlement of Boulder.

1414 Pine Street
The house is a good example of a classic cottage deign
and retains most of its original architectural details,
including a cornice with incised scrolls, wooden porch
trim, segmental brick arches, and, most notably, wooden
bay windows. In 1900, Samuel D. Hum lived here with
his family. Hum was a railway auditor who was born in
Pennsylvania in 1866.
SOM-45
1424 Pine Street
This house is a good example of a small Victorian
cottage, with detailing which is usually found on a
larger home. The residence was built in 1890 by Frank
Lounsberry, who was engaged in the lumber and
building materials trade.
SOM-47
1514 Pine Street
This house, with its decorative shingles and
Romanesque window, was constructed before 1900.
It is a good example of a smaller Queen Anne style
house, and adds to the architectural diversity of the
Whittier neighborhood. In 1900 this was the home of
Harry Gamble, an attorney, and his wife Jessie.
SOM-48
Grieder House
1836 Baseline
The Calvin and Florence Grieder house, built in 1949,
was designed by local architect Jacques Hampton.
The structure is representative of the Wright Usonian
style with its horizontal lap siding set under a flat roof,
featuring horizontal ribbon windows along the front
facade, just under the broad overhanging eave. The
horizontal composition of the structure is interrupted
by two massive, vertically oriented sandstone chimney
towers. The house features a U-shaped plan with
the open side facing south. The enclosed patio is
approximately 50 feet by 30 feet, with a large Hopa
flowering crab tree in the center. On the west wail of
the patio is a fresco 7 feet by 10 feet, designed by the
Grieder’s elder son, Terence Grieder. The decorative
use of pink Lyons sandstone is also featured on the
interior fireplaces, two planters, and entrance hall. This
house is also significant for its association with Calvin
and Florence Grieder, original owners of the house.
Calvin Grieder, recently deceased (November 1994),
was professor of school administration at the University
of Colorado from 1940 to 1972. Calvin was founder
of the Colorado Association of School Boards and
founding editor of the Colorado School Board Bulletin.
In 1945, he became full professor at the University of
Colorado. He served as director of graduate studies
in the School of Education, was a member of the
Faculty Council and the budget committee, serviced
twice as acting dean of the Graduate School and twice
as acting dean of the School of Education. He retired
with the rank of professor emeritus and was awarded
the Stearns Award for extraordinary service to the
university. He co-authored seven books on education
and 300 articles and monographs on administration.
Florence Grieder was a member of the Boulder School
Board from 1949 to 1961, serving as president the
last six years. She-was active in state and local parent-
teacher associations, and on the board of the Colorado
Mental Health Association. She was the president of
the Faculty Women’s Club from 1967-68. Sons include
Terence, professor of art history at the University of
Texas in Austin, and Timothy, academic officer at the
Colorado Commission on Higher Education at Denver.
SOM-49
1420 Bluebell
This Prairie Ranch style house was built in 1952. The
design, by Erphriam Hatch, was featured in the May,
1952 issue of Better Homes & Gardens, which showed
pictures of the built model in Provo, Utah. Mr. and Mrs.
Robert C. Reinke purchased a set of the
plans from Hatch. Incorporating ideas from their home
in Michigan, designed by prominent architect Alden
Dow, the Reinkes adapted and refined the plans for
their property in Boulder. Both Hatch and Dow were
influenced by the designs of Frank Lloyd Wright, as
reflected in the building’s horizontality. The horizontal
one story, asymmetrical building combines a side-gable
low pitched roof with a projecting flat roof carport
(later converted to a garage) and features clerestory
windows above the recessed entry. Exterior materials
include brick and vertical wood cladding; the southwest
wall is of “post and beam” and glass construction.
Robert Reinke, original owner of the house was a
graduate of Crane Technical High School in Chicago
and the University of Illinois. He worked as a chemist
for Dow Chemical Company in Midland, Michigan from
1936 to 1952. He worked as a spectroscopic for Dow
at the Rocky Flats nuclear weapons plant from 1952
to 1979. Reinke published articles in the Chemical
Engineering News, was active in the Boulder Lions Club
and the Society for Applied Spectroscopy, and was a 50
year member of the American Chemical Society.

Barnes-Schwalbe House
896 17th Street
Haertling created a sensitive and imaginative addition to
this small stylish Usonian home. Built in 1948, the home
was one of the first post WWII modem structures in
Boulder. Architect Jacques Hampton was the designer
and original owner. The house is traditional materials,
brick and wood. Haertling picked up on the palette
of colors and materials, but created an addition that
was respectful but different. This house is also called
the Barnes House, after Hazel Barnes, who was the
owner at the time the addition was created. Ms. Barnes
was a renowned academic who made substantial
contributions to the translation of Sartre.
SOM-51
Wheat House
1515 Baseline
Originally built in 1923, Jon Ben Wheat commissioned
an addition in 1958 and a remodel in 1963 to
transform this home into a modern design. Featuring
an inverted roof line that allows a feeling of the
outdoors to become part of interior space, this was
one of Haertling’s firm’s first buildings.

Albersheim House
1440 Bellevue
Constructed on a lot with spectacular views in opposite
directions, this wood structure is entirely coved in
cedar shingles, even the soffits. During construction the
Albersheim family insisted that the house be parallel
to the street, but still wanted to enjoy the views of
the surrounding area. To accomplish this, Haertling
designed an elongated floor plan, with sleeping areas
on each end of the house connected by two long glass
walls.
SOM-53
Yokum Building
1714-18 Broadway
The original building was built in 1914 and remains a
fine example of early twentieth-century commercial
architecture. It was purchased in 1932 by Daniel
Yokum, a photographer who merits recognition as an
important figure in Boulder’s history. In 1975 Charles
Haertling acquired the building and renovated the
interior for use as a restuarant and added a section to
the south side whichhe used as his architectural office
from1976 until his death in 1984.
SOM-54
Knudsen House
420 Christmas Tree Drive
The Knudsen house is an excellent example of the
Usonian style. The house has strong horizontal lines,
with a flat roof, strong symmetry, and the use of
cantilever. The materials are brick, polished aggregate
and wood and glass curtain walls. The house is built
into a steep slope, just below Flagstaff Mountain. The
landscaping is naturalistic, with evergreen trees and
large boulders.

City of Boulder Landmark No. 161
Wilson-Haertling House
The original owners were a married couple, a CU
professor and an artist. Two years after the home was
completed, an arsonist’s fire damaged it badly. Some of
Mrs. Wilson’s paintings were destroyed, and the couple
decided not to rebuild the house. Charles and Viola
purchased it, and did a painstaking restore to the house.
Joel was 13 at the time. He lived in the house off and
on until his 30s. Viola continues to live and teach piano
lessons from the home. The house has a triangular plan
with three pavilions. The sculpturally shaped walls are
covered with horizontal wood siding. The house is on a
wooded lot, with natural state landscaping. Trees have
grown around the house and shelter it from the street
and surrounding houses.
SOM-56
McConnel House
450 College
This elegant home has a triangular wing that forms a
dramatic cantilever over a steep wooded hillside. The
hillside is landscaped in a naturalistic style. Many trees
are reaching maturity, and now provide screening and
privacy for the home. From a formal living room, the
inhabitants have a panoramic view of Boulder through
a glass curtain wall. Materials are stucco glass, and
wood. A small plateau on the west side of the house
creates a sheltered garden and entrance. The original
owner was James McConnell.
SOM-57
Jourgensen House
780 Flagstaff
The Jourgensen House is unusual, among Haertling’s
designs.” It is intensely masculine and geometric, assert-
ing itself on the hillside where the mountains meet the
plains. The interior is dominated by the curved forms of
vertically spacious then his other designs. The land-
scapithe white concrete towers, and interior is moreng
is also unique, with more formal terracing then his oth-
erhomes. Linda Jourgensen and her husband commis-
sioned the house. Mrs. Jourgensen served on Boulder
City Council, and still lives in the house. The design is
centered around four cylindrical towers, reminiscent of
grain silos. Each tower contains a function. One is a
spiral staircase with a “fireman’s pole” in the middle.
Another is a fireplace and the third and fourth are
storage and utilities. The center has a three story open
pavilion, while each cantilevered wing has a two-story
space. The exterior is a self-sealing copper, which has
aged to a beautiful patina.
SOM-58
Roitz House
1135 Jay Street
Perched upon a steep hillside lot in West Boulder, the
Roitz House was constructed for a client wanting a low
cost, energy efficient house. In addition, it was request-
ed that the house included areas to view the surround-
ing area while also being spacious enough for two
adults, two children and a professional photography
darkroom. Haertling accomplished these requests by
essentially designing a pyramid with recessed balcony
that takes advantage of the limited sunlight and created
a central living area.
SOM-59
Johnson House
630 Northstar Court
The eccentric residence was designed in response
to a challenge placed upon the architect by a young
newspaper editor. Interested in solar energy, the owner
sought a structure that would use solar assistance but
maintain beauty through curved lines and surfaces. In
addition, the structure was to have an open and spa-
cious living space with ample area for family privacy.
To accomplish these requests, Haertling built two re-
inforced concrete towers in which served as a stair
connecting the separate child and parent levels and
the other as a solar tower. The house is then wrapped
around these two towers to create a feeling of open-
ness. In addition, the ceiling is curved and accentuated
by a beveled mahogany paneling.

White House
630 Pennsylvania Street
Next door to the Noble House (650 Pennsylvania
Street), this home includes several trademark
architectural Haertling features including white
balconies, stacked block walls, and very large window
surfaces.
SOM-62
Noble House
650 Pennsylvania Street
This home is a pair of pyramidal structures, connected
by a central entrance. Haertling offset the angle that
the house addressed the street, to increase the privacy
of the entrance. Each pyramid is topped with a slender
spike that doubles as a skylight. Remarkably skilled
craftsmanship was necessary for the joinery required
to create these complex and unusual forms. The long
roof lines of the home nearly touch the ground in
some places. The rounded pyramid forms help to make
the house feel organic; one can imagine it grew up as
part of the forest. The context is a heavily wooded site;
large trees surround the house and create a haven
from an otherwise traditional pre-WWII residential
neighborhood.
SOM-63
Krueger House
1025 Rosehill Drive
Haertling designed this house to fit gently into a sloping
hillside. The building’s low horizontal roof forms have
earned it the nickname of the “poinsettia house;”
elegant as a flower. The design includes cubist volumes,
windows at wall intersections, and use of cantilever.
The materials are wood, glass, and stone. Similar in its
organic quality to the Noble House, the Kreuger house
seems to grow amongst large trees of its forest setting.
The house is intimate -it is recessed ten feet below the
grade of the road, to which its back is faced. It is further
recessed into the hillside 18 inches. Approaching the
house from the street engenders a sense of trespassing
on sacred or private space.
SOM-64
Knitting Mill
719 Walnut
The Alpine Knitting Mills are an example of Haertling’s
debt to prairie style architecture, and the strong link
between Prairie and Usonian. The building has large
overhanging eves, and strings of ribbon windows. The
roof is cast concrete, and the walls are concrete block
with horizontal raked joints. The structure is in a more
urban context then most of the homes surveyed here.
It responds to its site, respecting the setbacks and
mass of the neighboring buildings, while still paying
homage to nature. This is demonstrated in a cutout
in the roof created to accommodate a tree on the
site. Haertling also maximized the use of glass, planter
boxes, courtyards, and balconies to create a strong link
between indoors and outdoors.
