APPLICABLE CITATIONS:
Historic Design Guidelines, Chapter 3, Guidelines for Additions
1. Massing and Form of Residential Additions
A. GENERAL
i. Minimize visual impact-Site residential additions at the side or rear of the building whenever possible to minimize views of the addition from the public right-of-way. An addition to the front of a building would be inappropriate.
iii. Similar roof form-Utilize a similar roof pitch, form, overhang, and orientation as the historic structure for additions.
iv. Transitions between old and new-Utilize a setback or recessed area and a small change in detailing at the seam of the historic structure and new addition to provide a clear visual distinction between old and new building forms.
B. SCALE, MASSING, AND FORM
i. Subordinate to principal facade-Design residential additions, including porches and balconies, to be subordinate to the principal façade of the original structure in terms of their scale and mass.
iv. Footprint-The building footprint should respond to the size of the lot. An appropriate yard to building ratio should be maintained for consistency within historic districts. Residential additions should not be so large as to double the existing building footprint, regardless of lot size.
v. Height-Generally, the height of new additions should be consistent with the height of the existing structure. The maximum height of new additions should be determined by examining the line-of-sight or visibility from the street. Addition height should never be so contrasting as to overwhelm or distract from the existing structure.
3. Materials and Textures
A. COMPLEMENTARY MATERIALS
i. Complementary materials-Use materials that match in type, color, and texture and include an offset or reveal to distinguish the addition from the historic structure whenever possible. Any new materials introduced to the site as a result of an addition must be compatible with the architectural style and materials of the original structure.
B. INAPPROPRIATE MATERIALS
i. Imitation or synthetic materials-Do not use imitation or synthetic materials, such as vinyl siding, brick or simulated stone veneer, plastic, or other materials not compatible with the architectural style and materials of the original structure.
FINDINGS:
a. Consistent with the Guidelines for Additions, new additions should be located at the side or rear of the building, use a similar roof pitch and material than the existing structure, have a footprint that responds to the size of the lot, and be consistent with the height of the existing house. The proposed porch addition is consistent with the guidelines in location, roof form, footprint and height.
b. According to the Guidelines for Additions, a setback or recessed area should be used to provide clear visual distinction between old and new. The proposed addition aligns with the west wall of the house and is not consistent with the guidelines.
c. New additions should incorporate materials that are compatible with the architectural style and materials of the original structure as recommended by the Guidelines for Additions. The proposed corrugated tin skirt is not a typical skirting material used in historic districts and is not consistent with the guidelines. A wood siding or stucco skirt to match the house would be more appropriate.
RECOMMENDATION:
Staff recommends approval with the following stipulations based on findings a-c:
a. The west wall of the addition is set back so that it is not flush with the house.
b. Wood siding or stucco is used instead of corrugated metal.
