310 E 23Rd St

The Foundry is a 12-story prewar condop in Gramercy, built in 1906 and converted from a factory into 38 residential loft-style units. The building’s industrial bones are evident in soaring 11-foot ceilings, large multi-pane windows, exposed brick in some units and open, flexible layouts that accommodate studios, junior one-bedrooms and three-bedroom lofts with sleeping alcoves or mezzanines. Many residences feature hardwood floors, updated kitchens with stone counters and stainless appliances, custom storage solutions and renovated baths; several listings note built-in loft beds, walk-in closets and space for home offices or dining areas. Common areas include a newly refreshed lobby, planted and furnished roof deck with grills, bike room, storage rooms, coin or card laundry and video intercom entry; a live-in superintendent manages onsite needs. The Foundry’s ownership structure is a condop with buyer-friendly policies: co-purchasing, guarantors, parents buying with/for children, pieds-à-terre and washer/dryers permitted, live/work allowed and unlimited subletting after one year in many cases. Pets are welcome. Located near Union Square, Gramercy Park and multiple subway lines (6, N/R/W, L), the building offers a central downtown lifestyle with immediate access to shops, restaurants and transit.
