Exterior rehabilitation and dormer addition. Existing rear addition to be partially removed. Exterior staircase on the side elevation to be removed.

Exterior rehabilitation scopes include the removal of existing siding and the installation of new fiber cement lap siding, repair and replacement in patches to the brick foundation, and replacement of windows and doors. New window on the façade. The front porch will be reconstructed; the partial-width front gable roof will be reconstructed as a front-gable roof porch that extends the full length of the façade (reflected by existing foundation). The porch will feature four tapered brick columns and a new railing.

New rear dormer addition. Clipped-gable roof dormer to be added to rear roof slope, featuring an exterior clad in lap and shingle siding and two pairs of double-hung windows on the rear elevation.

CONDITIONS OF APPROVAL PER HZC 10.17.2024: 1) final site plan to meet City Engineering standards and requirements of the base zoning; 2) porch width, roof pitch, and roof design of existing/original porch to be retained; 3) omission of the new window proposed for the façade; 4) height of new dormer addition to be beneath the roof peak of the main roofline.

1. 1724 Highland Ave is a contributing resource to the Fort Sanders National Register Historic District and local NC overlay.

2. The application includes the removal of the existing wood siding, and the installation of new fiber cement lap siding which meets the Fort Sanders design guidelines. The existing house has a Tudor Revival-style siding on side gable fields, with shingles in the porch gables and the lower bay on the left side elevation. The project should incorporate appropriately sized vertical cornerboards and window trim. Only the porch roof includes triangular Craftsman-style brackets on the existing house; such details should be incorporated in the new porch roof.

3. The application includes removing the partial-width, front-gable roof front porch and reconstructing a new porch with a full-length front-gable roof and three tapered brick-clad columns to match the existing. Based on the 1924 (revised 1950) Sanborn Fire Insurance Map, the width of the existing porch roof is original. The brick knee wall on the right side looks to be a later addition. The porch width, roof pitch, and roof design (including elements such as eave overhangs, fascia boards, and decorative brackets) should be retained in reconstructing the porch.

4. The window pattern on the side elevations, including the projecting bay on the left side elevation with four adjoining double-hung windows, will be retained. An extra window is proposed for the right bay of the façade; the façade window and door arrangement should be retained.

5. In general, the placement of a new addition on the rear roof slope is appropriate within the design guidelines. The height of the new dormer addition should not exceed the roof peak of the house's original side-gable roof, to reduce visibility from the street. The applicant should clarify the proposed siding for the rear dormer; elevations show shingles on the side and lap siding on the rear, and one siding material may be preferable for design consistency.

6. Final modifications to the site plan will be necessary to meet City Engineering standards for parking. The house and parking should remain within the impervious surface requirements for the base zoning. The final site plan could be approved by staff, provided there are no substantial modifications to the addition's design and placement.
