Design Review Board

Level 2: Addition to an existing building/structure

7-B-21-DT

Staff Recommendation

Staff recommends approval of Certificate 7-B-21-DT as submitted, with the condition that deck and patio elements are set back at least 18" from the building edges, meeting section 10.3.N of the City Zoning Code.

Applicant Request
Rooftop modifications, including a new deck/patio area to the rear of 414 Clinch Avenue. Patio includes an outdoor kitchen, pergola structure, and additional roof-level amenities. Work is proposed for the rear-facing roof section, facing the surface parking area between the building and W. Church Ave. An existing rooftop addition will block the project's visibility from Clinch Avenue.

A standing seam metal canopy will extend from the existing rooftop addition approximately 9'-1". On the left side elevation, a Trex privacy screen/horizontal fence will extend from the existing addition to the proposed pergola. The Trex pergola is approximately 9' tall, featuring vertical slats on the leftmost elevation, and square post supports. The pergola is recessed from the rear building edge by approximately 14'. Glass guardrails will wrap around the patio area, excepting the area which will receive a "QuietFiber-lined AC enclosure." Additional features include Trex decking; privacy planters on side, rear, and interior elevations; and repair and paint to the cedar siding on the existing rooftop addition.
Staff Comments
414 Clinch Avenue (known as Sandstone Court) is not listed on the National Register of Historic Places, so the Historic Resources section of the guidelines does not apply. The proposed undertaking includes a number of minor modifications which do not affect the character-defining features or façade view of the building, including Trex privacy fencing, a Trex pergola, a standing-seam metal canopy, and a glass guardrail.

The proposed work will not be visible from Clinch Avenue, due to the existing rooftop structure located closer to Clinch Avenue, which extends the width of the building. All new features are located at the rear of the building, fronting a surface parking lot. The proposed elements will be minimally visible from Walnut Street across the parking lot.

All proposed elements are minor in scope and could be easily removed without further effect on the building. The pergola is less tall than the existing flat-roof addition. All deck and patio elements will need to be set back at least 18" from the building edges, per City Zoning Code (10.3.N).
