Exterior rehabilitation of existing secondary structure (garage). The existing garage features a front-gable roof clad in asphalt shingles, an exterior of wood lap siding, and a concrete block foundation, with a garage door fronting the alley.
- Replacement of existing roof: the application includes two options for new roof cladding: 1) "Tuff-Rib" metal panel roofing and 2) architectural shingles.
- Removal of existing garage door, installation of wood lap siding to match the existing.
- Removal of non-historic secondary door on south side elevation of garage, installation of wood lap siding to match the existing.
- Removal of double-hung window on interior (west) elevation, installation of paired, full-light, steel doors.

CONDITIONS OF HZC APPROVAL 5/16/2024: 1) applicant select architectural shingle cladding for the roof replacement; 2) applicant install a double-hung window in place of the removed garage door on the alley-facing elevation.

1. 810 Luttrell St is a contributing resource to the Fourth and Gill National Register Historic District and local overlay. No specific date is attributed to the garage but it is not visible on the c.1985 aerial and features a modern concrete block foundation.

2. Replacement of the existing roof is appropriate; guidelines recommend asphalt shingles, or standing-seam metal or metal shingle claddings. Of the two options presented in the application, architectural shingles are the more appropriate roof cladding; the ribbed metal panel cladding is not a historic roofing material and not compatible with roofing materials in the broader neighborhood.

3. Removal of the non-historic hollow secondary door will not be visible from the right-of-way and does not result in the removal of character-defining features.

4. Removal of the double-hung window and installation of full-light paired doors on the garage's interior (west) elevation will not be visible from the right-of-way. The proposed steel material is appropriate for a secondary structure.

5. Design review for new secondary structures in Fourth and Gill (and similar districts like Old North Knoxville) has typically encouraged some transparency or detail on elevations fronting alleys. The removal of the garage door will result in a large swath of siding with no transparency. Existing garages and sheds along alleys in the neighborhood are mixed; some feature no transparency, but may have sides turned to the alleys, and some have gable windows. The Commission should discuss whether additional transparency or exterior detail is necessary on the alley-facing elevation.
