Exterior rehabilitation and new rear addition.

Exterior rehabilitation scopes include the removal of existing vinyl siding and installation of new fiber cement lap siding, repair and replacement in patches to the brick foundation, removal of exterior shutters, and replacement of windows and doors. Front porch will be reconstructed in kind, including new railings and new brick pier supports. Front dormer will be removed and reconstructed to fix structural issues.

New rear addition, to include a 5' deep addition on the rear elevation (continuing the existing side-gable roofline), and a new gable-roof dormer on the rear roof slope. The dormer features paired double-hung windows on the rear elevation, triangular brackets to reflect the primary house, and fiber cement lap siding.

CONDITIONS OF APPROVAL PER 6/20 HZC MEETING:
1) final drawings to indicate appropriately sized cornerboards and window trim, and to incorporate existing triangular brackets, rectangular vent, and roof details;
2) brick columns on reconstructed front porch to match existing in size and design;
3) final site plan to meet City Engineering standards and requirements of the base zoning.

1. 1708 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 exterior vinyl siding and the installation of fiber cement lap siding, which meets the Fort Sanders design guidelines. The project should incorporate appropriately sized vertical cornerboards and window trim, along with retaining existing details such as the rectangular louvered vent in the front dormer. The drawings indicate the triangular brackets and exterior brick chimney will be retained.

3. Reconstruction of the front porch and columns meet the design guidelines. The brick piers should be reconstructed with the same design and dimensions as the existing. The elevation drawings indicate the right side of the façade will be reconstructed, removing the brick piers that remain from a previously-enclosed porch; the applicant should clarify work to be completed on this elevation.

4. In general, the placement of a new addition on the rear elevation is appropriate within the design guidelines. The 5' rear addition and the new rear dormer are compatible with the overall scale of the existing house, and the dormer incorporates a roof pitch and details comparable to the house. The reconstructed front dormer should replicate the size, placement, and roof details of the existing.

5. The replacement door on the facade should meet the design guidelines ("similar proportions and features to pre-1940 architecture").

6. Final modifications to the site plan will be necessary to meet City Engineering standards for parking. The house and parking area 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.
