400 Riverside Dr

A low-rise prewar cooperative built in 1920, this six-story, masonry-clad residence reflects early 20th-century townhouse-scale architecture adapted for multiple-family living. The property is composed primarily of one-bedroom layouts, many retaining period details such as high ceilings, crown molding, decorative moldings and hardwood floors, with select units offering dens, separate dining areas and windowed kitchens and baths. Common areas include an entrance foyer and a formal lobby; building services are traditional and on-site — a live-in superintendent and video intercom/security system are noted in representative listings. Shared amenities are modest and neighborhood-focused: a planted courtyard/garden, bicycle storage and a communal laundry room; an outdoor hard-surface basketball court is also associated with the property. Parking is not a prominent feature. The coop allows pets and pied-à-terre arrangements in many instances and typically accepts guarantors and parental purchases, indicating flexible ownership policies. Located adjacent to Riverside Park and close to Columbia University, the building sits within a culturally rich, transit-accessible Upper West Side/Morningside Heights setting, surrounded by restaurants, shops and academic institutions. Overall, the property emphasizes preserved prewar character, manageable scale, and garden-side, park-facing living rather than full-service luxury.
