- New duplex fronting Johnston Street. Two story, front-gable roof residence measures 36' wide by 34' long, with a hipped-roof porch projecting approximately 6.5' and extending the length of the facade. The structure is proposed to be set 49' from the front property line. Parking is proposed to be a 1,444 square foot asphalt parking lot located in the front of the structure and accessed via Johnston St.
- The structure features a 6/12 pitch gable roof clad in three-dimensional shingles. The exterior will be clad in vinyl siding. The structure will rest on a concrete foundation and will feature 1/1 double hung vinyl windows.
- On the façade (east), the hipped-roof porch will feature a roof to be clad in dimensional shingles, supported by two 6" wooden posts. The porch will be divided by a centrally located wall, flanked by a door and two 1/1 double-hung windows on each side. The second story of the façade features two smaller 1/1 double hung windows. The left and right elevations (south and north, respectively) feature four windows on the first story and two windows on the second story. The first floor of the rear elevation (west) features two secondary access doors, each flanked by a small 1/1 double-hung window, that open to stairs leading down to a concrete patio. The second story of the rear elevation features two pairs of 1/1 double-hung windows.
Applicable Guidelines
Heart of Knoxville Infill Housing Design Guidelines
See Guidelines- 1. Front Yards:
- Consistent front yard space should be created along the street with the setback of a new house matching the older houses on the block.
- A walkway should be provided from the sidewalk or street to the front door. Along grid streets, the walk should be perpendicular to the street.
- Healthy trees that are outside the building footprint should be preserved. The root area should be marked and protected during construction.
- Consistent front yard space should be created along the street with the setback of a new house matching the older houses on the block.
- 2. House Orientation and Side Yards:
- New housing should be proportional to the dimensions of the lot and other houses on the block.
- Side yard setbacks should be similar to older houses on the block, keeping the rhythm of spacing between houses consistent.
- On lots greater than 50' in width, consider re-creating the original lot size.
- New housing should be proportional to the dimensions of the lot and other houses on the block.
- 3. Alleys, Parking, and Services
- Parking should not be in front yards.
- On streets without alleys, garages or parking pads should be at least 20 feet behind the front façade of the infill house with access limited to one lane between the street and the front facade.
- Parking should not be in front yards.
- 4. Scale, Mass, and Foundation Height
- The front elevation should be designed to be similar in scale to other houses along the street.
- The front façade of new houses should be about the same width as original houses on the block.
- New foundations should be about the same height as the original houses in the neighborhood.
- If greater height is to be created (with new construction or an addition), that portion of the house should be located toward the side or rear of the property.
- The front elevation should be designed to be similar in scale to other houses along the street.
- 5. Porches and Stoops
- Porches should be part of the housing design in those neighborhoods where porches were commonplace.
- Porches should be proportional to original porches on the block, extending about 8-12 feet toward the street from the habitable portion of the house
- Porches should extend into the front yard setback, if necessary, to maintain consistency with similarly sited porches along the street.
- Porch posts and railings should be like those used in the historic era of the neighborhood's development. Wrought iron columns and other materials that were not used in the early 1900's should not be used.
- Porches should be part of the housing design in those neighborhoods where porches were commonplace.
- 6. Windows and Doors:
- When constructing new houses, the window and door styles should be similar to the original or historic houses on the block.
- To respect the privacy of adjacent properties, consider the placement of side windows and doors.
- The windows and doors on the front facade of an infill house should be located in similar proportion and position as the original houses on the block.
- Attention should be paid to window placement and the ratio of solid (the wall) to void (the window and door openings).
- Contemporary windows such as picture windows should not be used in pre-World War II neighborhoods.
- When constructing new houses, the window and door styles should be similar to the original or historic houses on the block.
- 7. Roof Shapes and Materials
- New roofs should be designed to have a similar pitch to original housing on the block
- Darker shades of shingle were often used and should be chosen in roofing houses in Heart of Knoxville neighborhoods.
- New roofs should be designed to have a similar pitch to original housing on the block
- 8. Siding Material
- Clapboard-like materials (such as cement fiberboard) should be used in constructing new housing where painted wood siding was traditionally used
- Brick, wood shingle, and other less common material may be appropriate in some older neighborhoods, particularly those with a mix of architectural styles.
- Faced stone, vertical siding, and other non-historic materials should not be used in building new houses.
- Clapboard-like materials (such as cement fiberboard) should be used in constructing new housing where painted wood siding was traditionally used
- 11. Landscape and Other Considerations:
- One native or naturalized shade tree should be planted in the front and rear yards of in fi ll lots with 25 feet or more in depth to front of house.
