407 E 91St St

This is a low-rise, five-story prewar cooperative on Manhattan’s Upper East Side, originally built in 1901 as a piano/furniture factory and converted to loft residences in the 1980s. The 10-unit building (commonly described in listings as a 36-unit property depending on floor plan splits) preserves industrial character: high ceilings, wide, oversized windows, exposed brick and exposed wood beams appear throughout many apartments. Units range from one-bedroom lofts to duplex penthouses with private terraces; several homes include in-unit washers and dryers, open chef-style kitchens, and generous built-in storage and pantry areas. Common elements emphasize boutique living with an elevator, live‑in superintendent, central laundry room, package delivery area, and a video/sound intercom system. Exterior features include small private balconies, planted courtyard/garden spaces, and private outdoor terraces on upper floors. The building maintains a pet-friendly policy, allows washers/dryers in apartments, and historically permits subletting and pied‑a‑terre occupancy on a case-by-case basis. Located near Carl Schurz Park, Asphalt Green, and the East River Esplanade, the property offers convenient access to local buses and subway lines and is surrounded by neighborhood shops, groceries and restaurants, delivering a mix of downtown loft ambiance within an Upper East Side residential context.
