Applicable Guidelines

Mechanicsville Design Guidelines, adopted by the Knoxville City Council on September 20, 2011.

- E. Rules for Wood Wall Coverings
- 1. Synthetic siding is inappropriate and is not allowed either as replacement siding on existing buildings or new siding in new construction.
- 3. Replacement siding must duplicate the original. Replacing trim and patterned shingles must also duplicate the original material.
- 11. If artificial siding is present on any elevation of a building and must be removed in order to repair the building structurally, it can be replaced on the building if no more than 25% of any elevation's artificial siding is removed. If more than 25% of the artificial siding on any elevation is removed for repair, it cannot be replaced.
- T. Additions
- 1. Locate exterior additions at the rear of or on an inconspicuous side of a historic building, limiting the size and scale in relationship to the historic building, and using appropriate proportions.
- 2. Design new additions so that it is clear what is historic and what is new.
- 3. Consider the attached exterior addition both in terms of the new use and the appearance of other buildings in the historic district. Additions shall be distinguishable from the historic building, but shall be compatible in terms of mass, materials, size, texture, and scale. Additions shall be designed so they can be removed without destroying the form of the historic building.
- 4. New additions should not be visible from streets.
- 5. Before expanding the size of the historic house with a new addition, try reconfiguring interior space that does not define the historic character of the building in order to accommodate the new space needs.
- 6. Do not cause a loss of historic character through a new addition.
