Brooklyn-based architect Ellen Honigstock preserved the rustic feel of this small landmarked brick townhouse in Greenwich Village while bringing more light into the interior, enlarging several windows on the upper floors, replacing windows at the parlor level with tall French doors and balonies, and adding skylights to the third floor. N.B. Honigstock is also a founder of the Toeprint Project, which provides energy audits for existing buildings large and small, with an aim to rooting out wasteful energy use.
