Applicable Guidelines

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

- C. Porches
- 1. Historic porches on houses in Old North Knoxville 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.
- E. Wood
- 5. Wooden features shall be repaired by patching, piecing-in, or otherwise reinforcing the wood. Repair may also include limited 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.
- 7. Replace only deteriorated wood. Reconstructed in order to achieve a uniform or "improved," "new" appearance is inappropriate because of the loss of good historic materials.
- 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 from 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. If necessary, analyze the original mortar to determine the proportions of lime, sand, and cement. A 'scrub' technique shall not be used to repoint. The width or joint profile shall not be changed unless the change will return the joint to its original appearance. Sound mortar should not be removed.
- 8. Never repoint with mortar of high Portland cement content, unless that is the content of the original mortar.
- 9. Historic masonry shall not be coated with paint, stucco, vapor permeable water-repellent coatings, or other non-historic coatings.
- SOI Standards for Rehabilitation
- 6. Deteriorated historic features shall be repaired rather than replaced. Where the severity of deterioration requires replacement of a distinctive feature, the new feature shall match the old in design, color, texture, and other visual qualities, and where possible, materials. Replacement of missing features shall be substantiated by documentary, physical, or pictorial evidenc.
