New development is an infrequent occurrence in the East 20s, but from 121 East 22nd Street through to 122 East 23rd Street, Toll Brothers City Living is almost finished on their latest project, designed by the Office of Metropolitan Architecture. GMS is providing exterior envelope consulting services for this new mid-rise residential condominium building. The building will consist of two towers on a one story podium. Retail space and residential lobby space are to occupy the ground floor. Parking, mechanical, residential amenity spaces and retail will be included in the cellar level plan. The remainder of the building is residential condominium units.
