(A) Windows, besides providing ventilation and light, are crucial visual elements to the facade of a building. They are often linked to certain architectural styles, time periods, building practices, and craftsmanship. Window materials, size, configuration, shape and detailing all contribute to the appearance of a building. In addition, the alignment, pattern, and spacing of windows is an important unifying element in the historic district.
(B) If the original windows are retained and retrofitted, it may be cheaper than purchasing and installing new windows. Original sash can be routed and new glass installed. Window companies now routinely make custom sizes for preservation purposes. An owner may want to consider traditional storm windows to improve thermal efficiency.
(C) Display windows, transoms and upper story windows all add to the streetscape’s rhythm and patterns. Even horizontal elements such as lintels and sills tie a block of buildings together. An important idea to remember is that upper story windows can create an appearance of vitality and use, even if a second floor is not being used.
(D) Design guidelines.
(1) Original windows, hardware, hoods, lintels, pediments, sash, shutters, and sills shall be preserved. If damaged beyond repair, a reproduction of the original design shall be allowed.
(2) Retain original window openings, pattern and size.
(3) Transom windows may be of clear, tinted, beveled, etched, or stained glass.
(4) Decorative windows and windows made of stained, prism, beveled, cut, or other art glass shall be retained.
(5) Display windows shall be transparent. Blinds and interior shutters may be installed for office use.
(6) Shutters will be considered on a case by case basis. Shutters shall be the exact size of window opening.
(7) Storm windows shall have minimal visual impact on the historic windows. This can be achieved by painting the window, matching the location of the rails, and not covering detail.
(8) If a window has deteriorated beyond repair, window replacements shall match the original or the style of the building in proportion, pane configuration, profile, texture and color.
(9) True divided lights are encouraged.
