Section 10-C2300. GENERAL PROVISIONS

 

2300.1Windows are an important and integral part of the design of most buildings. They typically comprise thirty to forty percent of the surface area of the building's principal facade. In making a determination on proposed changes to windows, the Board and staff evaluate the effect of the proposal on the aesthetic values and the historical and architectural significance of the affected historic building. Factors in this evaluation include the architectural style and integrity of the historic building, and the design, material, color, and general appearance of the proposed work.

 

2300.2These window standards are based on the following principles:

 

(a)The historic character of a property and its distinguishing qualities shall be retained and preserved. The removal of historic materials or alteration of distinctive architectural features should be avoided.

 

(b)Deteriorated architectural features should be repaired rather than replaced.

 

(c)In the event that replacement is necessary, the new feature should match the historic in design, color, texture, and other visual qualities, and, where possible, materials.

 

2300.3To the maximum extent possible, these standards shall be applied so as to minimize harm to National Historic Landmarks and National Historic Landmark Districts.

 

2300.4The following terms specifically applicable to this chapter are defined in Chapter 99:

 

(a)Facade;

 

(b)Principal facade;

 

(c)Secondary elevation; and

 

(d)Character-defining feature.
