Description: Review of previously approved installation of two (2) new dormers at front street-facing roof slope and installation of new rear gable at an existing Contributing rated 1½-story, two-family residential building.

HDLC Guidelines:

Section 5, Page 11 of the Guidelines for Roofing state that Dormers, also known as dormer windows, protrude from the roof surface with a window providing light and additional headroom under roof eaves. Dormers can have various roof shapes but are typically gables. Property owners are encouraged to retain existing historic dormers and reconstruct dormers on buildings where there is clear evidence that they existed. Evidence can be historic photographs indicating a dormer or visible within attic roof framing. New dormers at historic buildings are not always appropriate. Certain building types and architectural styles did not traditionally include dormer windows. For those buildings that historically included dormers, they were often located on certain roof slopes; set back a certain distance from the roof eave; centered or evenly spaced relative to architectural features below; had a standard form, most often a gable roof form; with window types and styles similar to the remainder of the building; and trim complementing the building’s architectural style. When considering a new dormer, particularly at historic buildings, property owners are encouraged to consider comparable buildings of the same style and period including the location, form, spacing, dimensions, proportions, style and detailing. For example, dormers are not typically appropriate on side elevation roof slopes. Similarly, oversized dormers to accommodate egress windows or to capture additional interior square footage are often inappropriate.

Previous ARC Recommendations:

11/15/2022: The ARC voted to recommend conceptual approval with the final details to be worked out at the Staff level. The ARC also agreed that the proposed front dormers are appropriate, and that Option 2 was the preferred rear dormer option. The ARC also agreed that the ridge line of the new rear dormer should be lowered to align with the ridge line of the front dormers. This may require the proposed rear doors be replaced with smaller windows to accommodate the lower ridge height.
