For Lease by Owner. 52 Greene Street is a cast-iron building built in 1867 on one of the most recognized cobblestone blocks in SoHo. After a fire in the 1950s, two floors burned down leaving behind a three-story building for almost 80 years. It is now being rebuilt to its original five-story height with the Landmarks Preservation Commission, the lost floors reconstructed in their historic form, with a setback penthouse and private green roof above. Behind the facade is new construction throughout: full-floor office lofts of roughly 1,600 to 1,700 rentable SF each, new front and rear windows, ceilings of 10 to 12 feet, a dedicated heating and cooling system with fresh-air ventilation on every floor, and an elevator opening directly onto each plate. Every office floor is delivered as a single full-floor tenancy, so no floor is shared, and no common corridor is required. Retail meets the street at the ground floor with a 16 ft storefront, connected by internal stair to cellar retail and separate storage below. The fifth floor and penthouse are offered together as a duplex joined by internal stair, with two private terraces totalling 488 SF and a green roof at the top of the building. The building is offered whole or floor by floor, with delivery in Q4 2026. It is owner-developed and owner-managed. All areas are approximate and subject to final measurement. Rentable area is to be recalculated upon completion.
