5A - Landmark Alteration Certificate for 707 Maxwell Ave (HIS2009-00047) MEMORANDUM May 6"', 2009 TO: Landmarks Board FROM: Susan Richstone, Long Range Planning Manager James Hewat, Historic Preservation Planner Chris Meschuk, Historic Preservation Planner SUBJECT: Public hearing and consideration of a Landmark Alteration Certificate to add dormers and construct a two-story, 1,100 sq. ft. rear addition to the 2,300 sq. ft. contributing house and to erect a one and one-half story, two-car garage; all at 707 Maxwell Avenue in the Mapleton Hill Historic District (HIS2009-00047) STATISTICS: 1. Site: 707 Maxwell Avenue 2. Zoning: LR-1 (Low Density Residential Established) 3. Owner: Leonard Ashack 4_ Applicant: Leonard Ashack 5. Site Area: 7,000 sq. feet 6. Existing House: 2,300 sq. ft. 7. Date of construction: c.1905 8. Proposed Addition 1,100 sq. ft. 9. Proposed Garage 600 sq. ft. STAFF RECOMMENDATION: Staff recommends that the Landmarks Board adopt the following motion: The board denies the proposal for the reconstruction of a front facing balustrade and addition of dormers on the sides of the main house, construction of a 1,100 sq. ft. addition to that building, and the construction of a free-standing 600 sq. ft. garage at the rear of the property at 707 Maxwell Avenue (as shown on landmark alteration certificate drawings dated 03.20.2009), in that it fails to meet the standards in Chapter 9-11-18 (a)(b, 1-3), B.R.C. 1981, and is not consistent with the Mapleton Hill Historic District Design Guidelines, the General Design Guidelines, in that the proposed work will damage the historic character of the property and AGENDA ITEM #5A PAGE 1 the immediate area. SUMMARY: • The house at 707 Maxwell Avenue is a contributing resource to the Mapleton Hill Historic District. • On March 251', 2009 the Landmarks design review committee referred the application for the construction of a rear addition and construction of dormers on the historic house. The applicant has revised the proposal and included the construction of a 600 sq. ft. two-car garage to the application. • Staff recommends the Landmarks Board deny the application finding that it does not meet the standards for issuance of a Landmark Alteration Certificate in Chapter 9-11-18, B.R.C. 1981. ~kr -•NIz4r c• i Ir ' fir yL'~ ;7I •4 1i ;5~~ r Figure 1. 707 Maxwell Ave, south elevation. DESCRIPTION: Constructed about 1905, the classic brick and wood frame four-square house at 707 Maxwell Avenue features a hip roof, wide overhanging eaves, and a full front porch with neo-classical design elements. In 1996, the front facing dormer was added to the house and a one-story addition at the rear of the house. AGENDA ITEM #5A PAGE 2 t. , ~7-.~.'+!.'t::'', - ~ Figure 2. 707 Maxwell Ave, south elevation, c.1929. The property is considered contributing to the Mapleton Hill Historic District, and would be considered contributing to the identified eligible National Register District (see Attachment A Historic Building Inventory Record). Research indicates that in 1910, the house was owned by William and Mary Donisfelder who came to Boulder from Geneseo, Illinois in 1903. After William's death, his daughters Edna and Lorena were declared incompetent by family and friends and committed to an insane asylum. They later escaped from the institution. In 1930, Edna is listed as the owner of the house. She died in 1979. 7Rr .Vo A 4k - I . ~fV.+ti', 4t15`(rJ f t t ""tt.4xa Figure 3. 707 Maxwell Ave, north elevation (from alley).

Fenestration is shown to be similar to that of the main house with one over one, double-hung and casement windows. Stylistically, the proposed addition is similar to the Four-Square house integrating neo-classical elements on the rear porch. •1 Figure 4.

AGENDA ITEM 95A PAGE 4 The existing non-lustoric one-story 220 sq. ft. 1996 addition at the north (rear) elevation of the house is to be removed to make way for a larger two story addition. In plan, the addition is shown to feature a slightly offset hipped roof intersecting with the hipped roof of the historic house. On the east a one-story addition is shown to extend out beyond the plane of the main house. At the first story, the addition is shown to extend 24 ft. from the north wall of the historic house and to be 32 ft. wide. The second-story is shown to also be 24 ft. in length and 20 ft in width. - f`- I R-O" I:' I I ' r - o ~I7 i I T<<.~ I a ~I ;Ild l_ I! i yr 'I ~Ii ''i fi ~ h•I r i Figure 5.

(b) Neither the landmarks board nor the city council shall approve a landmark alteration certificate unless it meets the following conditions: (1) The proposed work preserves, enhances, or restores and does not damage or destroy the exterior architectural features of the landmark or the subject property within an historic district; (2) The proposed work does not adversely affect the special character or special historical, architectural, or aesthetic interest or value of the landmark and its site or the district; (3) The architectural style, arrangement, texture, color, arrangement of color, and materials used on existing and proposed structures are compatible with the character of the existing landmark and its site or the historic district; (4) With respect to a proposal to demolish a building in an historic district, the proposed new construction to replace the building meets the requirements of paragraphs (b)(2) and (3) above. (c) In determining whether to approve a landmark alteration certificate, the AGENDA ITEM 95A PAGE 8 landmarks board shall consider the economic feasibility of alternatives, incorporation of energy efficient design, and enhanced access for the disabled. ANALYSIS: 1. Does the proposed application preserve, enhance, or restore, and not darnage or destroy significant exterior architectural features of the landmark or the subject property within an historic district.? Staff finds the proposed reconstruction of the balustrade above the front porch on the historic house and the proposed construction of the rear addition will not damage or destroy the exterior features of the contributing house as it is generally compatible and consistent with the Mapleton Hill and General Design Guidelines. However, it is staff's opinion that addition of the two side dormers will damage the architectural features of the house by altering the hipped roof form of the building. Likewise, the size and design of the one and one-half story garage will adversely affect the character of the property and the cumulative effect of the proposed new construction will reduce the proportion of built mass to open space on the property and will damage the historic character of the property. 2. Does the proposed application adversely affect the special character or special historic, architectural, or aesthetic interest or value of the property and/or district? Staff finds that the proposed dormers and new garage will adversely affect the special character of the property. The dormers will alter the essential form of the hipped roof and the size and design of the garage is uncharacteristic of the property and alleyscape. At a current FAR of approximately .33, the amount of built mass in proportion to the lot open space on the property is slightly lower than the average (.38) for the immediate area. With the proposed new construction, the FAR of the property will increase to .55 (not including possible usable area in the attic space of the main house). 3. Ts the architectural style, arrangement, texture, color, arrangement of color, and materials used on existing and proposed structures compatible with the character of the historic district? Materials proposed for the addition and freestanding construction are generally compatible with the character of the property and historic district. AGENDA ITEM #5A PAGE 9 c. The Landmarks Board is required to consider the economic feasibility of alternatives, incorporation of energy-efficient design, and enhanced access for the disabled in determining whether to approve a Landmark Alteration Certificate. No information was provided. ANALYSIS: The Historic Preservation Ordinance sets forth the standards the Landmarks Board must apply when reviewing a request for a Landmark Alteration Certificate. The Board has adopted the General Design Guidelines to help interpret the historic preservation ordinance. The following is an analysis of the proposed new construction with respect to relevant guidelines. Design guidelines are intended to be used as an aid to appropriate design and not as a checklist of items for compliance. GENERAL DESIGN GUIDELINES ALTERATIONS TO CONTRIBUTING BUILDINGS, 3.0: 3.1 Roofs The roof is one of the primary character-defining features of a historic building, and the repetition of similar roof types creates part of the visual consistency that defines a historic area. Alterations or additions to roofs must be given careful consideration to ensure that they do not compromise the integrity of the historic building. Typical roof shapes are gabled or hipped. Shed roofs sometimes occt.ir on historic additions and accessory buildings. Guideline Analysis Conforms?

BUILDING ALIGNMENT Traditionally, regular-sized building lots were laid our along rectilinear streets, and houses were generally built the same distance back from the street. Houses on most blocks in the Mapleton Hill Historic District reflect this pattern, and the regular alignment is one of the strongest visual elements of the district.

MAJOR EXTERIOR RENOVATION, ADDITIONS AND SECOND STORIES Large additions and additional stories to a building frequently change the character of the structure. The diversity that characterizes the historic district is a result of the variety in the sizes of buildings and the differing architectural styles. A design response that respects this diversity is more appropriate. One-and-a-half story structures that were built prior to World War I present the most challenge. Additional stories, using non-traditionally sized dormers, and raising the existing roof are not appropriate unless the character of the structure is not compromised. Additions to the rear, or in some situations, to the side of the building, are more likely to preserve the original character of the structure and may be the most appropriate design response. Every attempt should be made to address the existing AGENDA ITEM #5A PAGE 17 fabric of the Mapleton Hill Historic District and meet the specific Mapleton Hill Design Guidelines.

Staff considers the proposed rear addition is generally consistent with General and Mapleton Hill Historic District Design Guidelines. Reconstructing the balustrade on the front porch roof visible in the pre-1929 photograph is consistent with the General and Mapleton Hill Historic District Design Guidelines. The request to add dormers to the historic house is inconsistent with Section 3.5 (5 & 6) of the General Design Guidelines in that the cumulative effect of three dormers on the house will alter the essential roof dominated form of the historic house which originally had no dormers (a dormer was added to the front of the house in the 1996). A second small dormer at the rear (north) of the house may be appropriate. Staff also considers the requested construction of a garage on the property to be inconsistent with Section 7.2 (4, 5, 6, 7, 8, & 11) of the General Design Guidelines. AGENDA ITEM 95A PAGE 18 Furthermore, the cumulative effect of the proposed new construction is inconsistent with Sections 4.4.3 and 2.1 of the General Design Guidelines. Staff encourages the applicant to revise the proposal to reduce the amount of new construction on the property by redesigning in a'manner consistent with the historic preservation ordinance and the General and Mapleton Hill Historic District Design Guidelines. PUBLIC COMMENT: None. FINDINGS: As outlined in the staff recommendation, the proposed addition and new construction at 707 Maxwell Avenue is not consistent with the purposes and standards of the Historic Preservation Ordinance hi that: 1. The proposed addition of dormers and new garage will damage historic features and the unique character of the property 2. The intensity of construction on the property and resulting proportion of built mass to open space on the property will be inconsistent with historic patterns in the neighborhood. - 3. The request is generally inconsistent with the Historic Preservation Ordinance and Sections 3 & 7 of the General Design Guidelines.

Project Description: Modify our current rear addition of approximately 300 sqft. (and add heat to room). Build room above addition. Incorporate dormers for storage. Construct garage for parking & office need. Garage: For winter protection and difficult parking with little kids due to the many rental properties we have all around us. We bought this home wanting this small separate space for my wife's Massage Therapy and Rolfing practice; so she could also be at home. Storage: For the LDRC meeting, the dormers were drawn incorrectly. Dormers are now drawn correctly, and to smaller dimensions than originally presented. The definition Foursquare home in the General Design Guidelines 2007 manual has side (and rear) dormers on the home. This has been our home since 2005; this is our second home in Mapleton Hill historic district, we love old homes. We agree with General Design Guidelines 2007 philosophy, and bought this home to raise our kids and to live for many years.
