555 Main St

Island House is a mid-rise cooperative complex on Roosevelt Island built in 1975 and organized across 19 stories in several connected addresses (551, 555 and 575 Main Street). The building mix includes studios and one- to three-bedroom residences laid out for both single occupants and families, many with renovated interiors featuring wide-plank oak floors, crown molding, and open living/dining plans. Units commonly offer eat-in kitchens or breakfast bars, formal dining areas, walk-in closets, his-and-hers closets in larger homes, and spa-style baths with soaking tubs; some apartments include in-unit washer/dryer and private storage. The property emphasizes communal facilities: full-time doorman and on-site management, a fitness center with access to a 20-meter indoor lap pool, multiple laundry floors, bike room and package room, plus landscaped two-story courtyards with playgrounds, grills, dog run and garden spaces. Outdoor recreation on the island — multiple parks, waterfront promenades, running and biking paths, sports fields, and farmers’ markets — functions as an extension of the building’s amenities. The coop permits pied-a-terre ownership, co-purchasing, and financing up to 80% in many sponsor-sale offerings; pet policies restrict dog size. Convenient transit links include the Roosevelt Island Tram, F train, and ferries, providing rapid access to Midtown Manhattan while the building’s setting delivers a quieter, community-oriented residential experience.
