HISTORIC LANDMARK COMMISSION APPLICATION FOR A CERTIFICATE OF APPROPRIATENESS AUGUST 7, 2024 HR-2024-077497 ROGERS-WASHINGTON-HOLY CROSS HISTORIC DISTRICT 2305 EAST 21ST STREET 8 – 1 PROPOSAL Construct a second, detached housing unit. PROJECT SPECIFICATIONS The proposed project is to construct a second, detached housing unit adjacent to the historic home facing East 21st Street, offset roughly 10 feet from the side of the house, in order to create a two-unit development. The front of the new construction is to be nearly flush with the historic and is two stories in height. Materials are proposed to match the original home, and the roof is similar is pitch and form. The fenestration pattern is mostly regular on the front, along with a glazed entryway door. At the sides and rear, this is not the case, and windows are placed according to the interior floor plan. DESIGN STANDARDS The Rogers Washington Holy Cross Historic District Design Standards are used to evaluate projects within the historic district. The following standards apply to the proposed project: 2.0 Lot Configuration 2.3: Preserve existing single-family development patterns by constructing one principal house-scaled building on each platted lot. Accessory dwelling units are permitted. The property remains one lot, with the second unit not being removed from the plat. 3.0 Site and Site Elements 3.1 Sidewalks/Walkways: Many of the block faces have walkways to the front of the houses. These walkways are typically simple and perpendicular to the street. Proposed access to the second unit front entry is a walkway aligned perpendicularly to the street and not wider than is needed. 8.0 New Construction of Infill (Principal Buildings and Accessory Dwelling Units) 8.1 Orientation, Setbacks, and Height The new construction has a setback almost matching with the original house and conforms to other houses in the district. The height of the two-story additional housing unit is 23 feet above grade at the peak of the roof. Though there is a slight slope to the entire lot, the average height above grade is below the 27 feet limit that new construction is not to exceed. The section of the lot that contains the new construction footprint is generally flatter than other sections of the lot, and this is to be retained and the lot not significantly re-graded. Neighboring houses within the district are all one-story, which the proposed project exceeds, though it is not necessarily incompatible. 8.2 Design and Style Though two stories in height, the proposed second unit matches the nearby contributing buildings in floor height and proportions. The materials are proposed to match the original house on the lot. The applicant has responded to questions raised during Architectural Review Committee meeting. 8.3 Exterior Walls Materials are proposed to match in size and dimension, with a brick skirt present at the ground floor exterior that matches the historic in height. 8.5 Roofs Proposed roof matches the historic in height, orientation, and scale. 8.6 Windows and Screens The dimensions of the proposed windows mostly match the proportions of the square front windows of the historic house, and changes suggested at ARC have been included in the revised design. 8.7 Doors The proposed single front door is narrow compared to the front door of the original home but is appropriate in glazing and surround. Summary The project meets the applicable standards. COMMITTEE FEEDBACK Simplify the window design, with emphasis on the horizontality of the windows, and attempt to keep them completely above the brick skirt where possible. Make the awning over the main entry line up symmetrically. Ensure cladding is not an exact match to the main house but is compatible. 8 – 2 STAFF RECOMMENDATION Approve the application. LOCATION MAP 8 – 3
