407 E 91St St

A low-rise prewar cooperative on Manhattan’s Upper East Side, this five-story red-brick loft building was erected in 1901 and later converted to residential use. The property contains roughly three dozen units primarily configured as two-bedroom lofts and larger duplex arrangements; many residences retain industrial-era details such as exposed brick, tall ceilings (commonly 10–14 feet), oversized windows, and hardwood floors. Interiors often feature built-in storage, walk-in closets, eat-in kitchens or larger chef-style kitchens, pantries, and in-unit washers/dryers where permitted. Common building elements include an elevator, a live-in superintendent, a central laundry room, a package room, and a modest lobby; some units enjoy private outdoor space in the form of balconies, small garden terraces, or substantial private roof decks on the penthouse level. The co-op maintains a pet-friendly policy, sound financials, and a small flip tax. Street-level conveniences and a parking garage are available nearby rather than on-site. Located a short walk from Carl Schurz Park, Asphalt Green, and the East River promenade, the building sits in a neighborhood defined by waterfront recreation, schools, and Upper East Side retail and dining options, with easy access to multiple subway lines and crosstown buses.
