This renovation and addition to a 100-year-old historic building restores the entrance on Lexington Avenue to its former grandeur. The project integrates the synagogue with that of an adjoining townhouse. Circulation was enabled between the spaces despite the fact that the floor levels of the two buildings did not match. The newly combined buildings house a Sanctuary, multi-purpose social hall, kitchen, daycare center, chapel, library, offices, and an apartment for the caretaker. The grand exterior stair of the original building is recreated on the interior, with a double-height vestibule leading to the Sanctuary above. The vestibule creates a transitional space between the secular city and the spiritual function of the synagogue. Renovation elements involve the restoration of historic detailing in the Sanctuary, including the cleaning of stained glass and skylights, the cleaning and repointing of the exterior facade.
