Site Locator Map – 312 W Hyman 312 Page 2 of 6 437 Rio Grande, Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com BACKGROUND: 312 West Hyman is a designated Aspen Modern landmark located on a 6,000 sf lot in the R-6 zone district. The house is a classic Chalet style building, completed in 1956 and locally designated in 2006. The historic orientation of the structure is not square to the property lines but is angled to face Aspen Mountain. The site includes several large pine and spruce trees of note surrounding this property. Julius Herman Birlauf, a Swiss-born immigrant, assisted his daughter, Genevieve Birlauf Leininger, with the construction that was inspired by both Swiss and Bavarian architectural styles found in small mountain towns of the Alps. Archives include an extensive family photo collection of the phases of construction, interiors, and family gatherings on the front porch. Family letters describe influences for construction, and the network of family and friends in Aspen while located at the house, underlining the house and family as important components of the heritage of Aspen. The original home is an excellent example of Chalet style architecture associated with early ski areas and mountain tourist locations around the world. Common architectural features include a simple, low pitched roof with large overhangs, a rectangular footprint, small horizontal windows, and a large balcony that runs along the length of the façade. Often first floor has less detail, the main entrance on a secondary elevation, and a white stucco finish, with the main living area on the second floor. Post War construction of the style often added large picture window(s) in limited locations, a variation from the traditional style found in the Alps. The exterior will often have decorative shutters, fascia, and porch railings in the shape of hearts or edelweiss motifs, which can be found at the 312 West Hyman, and is part of the character that adds to its landmarked status.

Alterations include the addition of small windows on the East elevation at the first floor, a character defining feature. c 1958 Fig.2: Recent image of 312 W Hyman, note nothing has been altered on this elevation. 04/2019 When the owner of 312 W Hyman proposed demolition of important property, it was purchased by the City of Aspen and designated historic to protect a culturally significant resource. After many years of the house serving the residential needs of City employees, it was sold to the current owner. Page 3 of 6 437 Rio Grande, Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com REQUEST OF HISTORIC PRESERVATION COMMISSION (HPC) The Applicant is requesting the following land use approvals: • Major Development (Section 26.415.070.D) to add small additions to the main structure of the historic home and construct a new addition to the rear of the property. . The Historic Preservation Commission (HPC) is the final review authority; however, this project is subject to Call-up Notice by City Council. PROJECT SUMMARY: The applicant proposes: 1. Two-story addition on the West elevation proposed as the primary entrance to the residence with a new interior stair to the second floor 2. Two-story addition on the North elevation proposed as additional living space 3. Wrap-around deck at the NE corner of the residence 4. New windows on the East, West and North elevations enlarging existing openings at the first and second floors 5. A change in the existing windows on the South elevation at the deck, enlarging to glass doors 6. New glass sliders at each of the garage door openings, while keeping the garage doors intact as a type of privacy door/shutter on the South elevation. 7. New triangular windows below the eaves at either side of the existing attic vent on the South elevation. Attic vent will be changed to a small window, as the current ceiling will be removed to allow for the existing roof trusses to be exposed. 8. New flush-mounted skylights to be added 9. New Chimney 10. New siding located on the East elevation STAFF COMMENTS: Staff strongly supports aspects of the current plan including minimal alterations to the landmarked structure, without moving the resource or creating an extensive addition, while proposing to reduce energy consumption and making an energy efficient home. Staff also supports the small garage proposed designed to meet setback requirements and minimal tree removal. However, staff cannot support a multitude of proposed design features that are in direct conflict with the design guidelines. These include the proposed addition to the West elevation, changing the window sizes with removal of the historically significant shutters, the addition of new windows to the primary (South) elevation and the change of windows to large doors, new siding on the historic resource, any and all roof penetrations including skylights and new chimney as proposed. Staff recommends a restudy for resolutions of the above items listed. Page 4 of 6 437 Rio Grande, Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com Staff recommends HPC further discuss the following topic in more detail. 1. Historic Landmark –Restoration and Alterations: A preservation plan will be required for the restoration of the historic resource outlining the existing conditions and the proposed treatments. Staff fully supports the restoration of the historic resource and the removal of non-historic materials, such as the non-historic double door front entrance. Staff supports a restudy of restoration and rehabilitation of missing and changed elements. 2. New Garage Addition – Form, Materials and Fenestration: The proposed new addition is small, detached and significantly setback from the house while remaining within the required setbacks. The new addition has a minimal footprint and is one story, allowing the main house to remain the important structures from all vantage points. Fenestration will require additional review. Current proposed siding appears to conform to requirements for materials to Additional information regarding materials to be reviewed during Final Review for compatibility. Staff finds the overall design of the new garage addition meets the relevant Historic Preservation Design Guidelines. 3. Site Planning and Parking: The proposed site planning respects the underlying zoning requirements for front, East side yard and rear setbacks, but the West side is historically located within the setback. Zoning has an extensive list of items for the applicant to review, one of which is the combined side yard setback. Engineering has requested the removal of the historic driveway, the addition of a sidewalk, and a review of Right of Way compliance. According to the Municipal Land Use Code, all residential dwelling units must provide two code compliant on-site parking spaces, as this plan does with one in the proposed garage addition, but another is required. Staff supports the location of the new garage addition but recommends a restudy of the proposed site design to address Engineering, Park, and Zoning’s referral comments and provide for two code compliant on-site parking spaces. REFERRAL COMMENTS: The application was referred out to other City departments who have requirements that will significantly affect the permit review. Please see Exhibit B for full comments. Engineering Department: 1. For Major redevelopment all ROW needs to be brought into compliance. 2. Remove railroad ties and existing driveway. Page 5 of 6 437 Rio Grande, Aspen, CO 81611-1975 | P: 970.920.5197 | cityofaspen.com 3. New access needs to be off of alleyway. 4. Sidewalk needs to be installed along W. Hyman.
