ADDITIONS
Recommendations:
1. Locate attached exterior additions atthe rear or on an inconspicuous side of a historic building, limiting the size and scale in relationship to the historic building. Proportion is very important.

2. Design new additions in a manner that makes 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. Design for the new work may be contemporary or may reference design motifs from the historic buildings. In either case, it should always be clearly differentiated from the historic building and be compatible in terms of mass, materials, size, texture, scale, relationship of solids to voids, and color.

4. Place new additions, such as balconies or solar greenhouses, on non-character-defining elevations, and limit the size and scale in relationship to the historic building.

5 . Rather than expanding the size of the historic building by constructing a new addition, try to alter interior spaces that do not define the character of the building to accommodate the new space needs.

6. It is best not to add additional stories. If required for the new use, make sure they are set back from the wall plane and are as inconspicuous as possible when viewed from the street.

7 . New work should not appear to be as old as the historic building. Do not duplicate the exact form, material, style, and detailing of the historic building in the new addition.

8. New additions should not cause a lessening or loss of historic character, including the historic building's design, materials, workmanship, location, or setting.
