Applicable Guidelines

Old North Knoxville Design Guidelines, adopted by the Knoxville City Council on November 25, 2004.

- A. Roofs
- 3. Repair or replace roof details (chimneys, roof cresting, finials, attic vent windows, molding, bargeboards, and other unique roof features). Use some of these details in designing new buildings.
- B. Windows
- 1. Original windows shall be reused if possible. It will be much less expensive and better historically to retain the original windows, and it is inappropriate to replace them with new windows that differ in size, material, or pane division.
- 2. If replacement windows are necessary, they shall be the same overall size as the originals, with the same pane division and the same muntin depth, width, and profile. They shall be the same materials as the original windows, which were generally wood.
- 3. True divided lights shall be used in replacement window sashes with more than one pane.
- C. Porches
- 1. Historic porches on houses in ONK should be repaired, or may replicate the original porch if documentation of its size and design can be discovered.
- 2. Design elements to be incorporated in any new porch design must include tongue and groove wood floors, beadboard ceilings, wood posts and/or columns and sawn and turned wood trim when appropriate. If balustrades are required, they must be designed with spindles set into the top and bottom rails.
- D. Entrances
- 3. It may be appropriate to design or construct a new entrance if the historic one is completely missing. Any restoration shall be based on historical, pictorial, or physical documentation. It shall be compatible with the historic character of the building or with adjacent buildings.
- 4. A replacement entrance shall not create a false historic appearance. A new entrance or porch must be compatible in size, scale, or material.
- 6. Rear entrances may not be altered to make them appear to be formal entrances by adding paneled doors, fanlights, transoms, or sidelights.
- 7. Secondary entrances must be compatible with the original in size, scale, and materials but clearly secondary in importance.
- E. Wood Wall Coverings
- 4. New construction must incorporate corner and trim boards and appropriate door and window trim to be compatible with adjacent historic buildings.
- 5. Wooden features shall be repaired by patching, piecing-in, or otherwise reinforcing the wood. Repair may also include replacement with matching or compatible substitute materials, when elements remain and can be copied.
- 6. Wood features that are important in defining the overall historic character of the building shall not be removed.
- 8. An entire wooden feature that is too deteriorated to repair or is completely missing shall be replaced in-kind. If features are replaced, the materials they are made with shall be compatible with the original in size, scale, and material. Replacement parts should be based on historical, pictorial, and physical documentation.
- F. Masonry
- 4. Identify and preserve masonry features that define the historic character of the building, including walls, railings, foundations, chimneys, columns and piers, cornice and door and window pediments.
- 5. Replace an entire masonry feature that is too deteriorated to repair. Use the remaining physical evidence to guide the new work, and match new to old. Examples can include large sections of a wall, a cornice, balustrade, columns, stairways, or chimneys.
- 7. Match replacement mortar to the original mortar in color, composition, profile, and depth.
- 8. Never repoint with mortar of high Portland cement content, unless that is the content of the original mortar.
- 12. Stucco surfaced masonry can be appropriate for foundation in new construction. Brick and stone can also be appropriate.
