40 Mercer Street is SoHo's signature piece of contemporary architecture — a glass condominium designed by Pritzker Prize-winning French architect Jean Nouvel in collaboration with hotelier André Balazs, completed in 2007 in the heart of the SoHo–Cast Iron Historic District. Its façade of glass animated with red-and-blue fenestration, capped by a deep-blue rooftop, has become an unofficial landmark of the neighborhood — a deliberate modern counterpoint to the surrounding cast-iron loft buildings, built under Landmarks Preservation Commission review precisely because of its historic-district setting.
The building's design DNA is unusually distinct. Conceived initially as a hotel and reworked into residences, it carries Nouvel's signature spatial ideas: 11-to-12-foot ceilings, vast floor-to-ceiling glass, and — most famously — electronically retractable window walls on certain residences, a feature that essentially opens an apartment to the air, a rarity in New York. The result is a building that lives differently from anything around it.
For buyers, 40 Mercer offers architect-driven, light-and-air SoHo living with a full amenity suite, in a 41-unit condominium that has held its place as one of downtown's most recognizable addresses since it opened.
Architecture and unit composition
Jean Nouvel's design is the building's whole argument. The glass curtain wall — punctuated by panels of colored glass and crowned by the blue rooftop — reads as a piece of contemporary art on a street of nineteenth-century iron façades, a contrast that the historic-district review process ultimately endorsed. The 11-to-12-foot ceilings and floor-to-ceiling glazing flood the residences with light, and the retractable window walls on select homes are the design's most theatrical gesture, dissolving the boundary between apartment and sky.
The 41 residences span roughly thirteen to fourteen stories, with layouts that range from spacious lower-floor homes to the penthouses that crown the building. As an architect-driven project, the apartments emphasize volume, glass, and finish over a uniform stack of lines — each floor reads individually, and the upper residences command the open light and outlooks that the glass envelope was designed to capture.
Building operations
40 Mercer runs as a full-service condominium with a deep amenity program for its size: an indoor lap pool, a fitness center, spa treatment rooms, a steam room and sauna, a private garden courtyard, a residents' lounge, a screening room, and a children's playroom — a wellness-and-social roster more typical of a far larger building, reserved for 41 households. The lobby is attended, and common charges reflect that staffing and the amenity package; real estate taxes are billed per unit in the standard condominium structure.
The condominium format gives the building the ownership flexibility SoHo buyers expect. Financing is flexible, purchases clear through a right-of-first-refusal rather than a board interview, and pied-à-terre, trust, LLC, and investment ownership are customary — well suited to the international and design-minded buyers the building attracts. Subletting and pet specifics follow the condominium's governing documents and are confirmed through the managing agent.

Facade safety — Local Law 11
The facade passed its last inspection with no required repairs — nothing to budget for here, and no facade assessment on the horizon for roughly five years.

With 41 residences, turnover at 40 Mercer is light — a handful of resales in a typical year. Pricing reflects the building's architectural pedigree, the SoHo Historic District location, ceiling height, light, and floor level, with the retractable-window homes and upper-floor residences commanding a premium for their distinctive volume. Comparable analysis belongs against SoHo's other high-design lofts and condominiums rather than against generic downtown stock — the Nouvel design is itself a value driver. The building's auto-generated sales record reflects recorded transfers as they post; for a read on a specific line, a building-specific valuation is the right tool.
What to know if you’re buying
The case for buying here is design and light in condominium form. You are buying a Jean Nouvel building — one of the few in New York — with extraordinary ceiling height, walls of glass, and, on select homes, retractable windows that no other building offers, plus a full amenity suite and the ownership flexibility of a condominium in the SoHo Historic District. The trade-offs are that the architecture is assertive and specific: the glass envelope, the colored fenestration, and the open layouts suit buyers who want a contemporary, light-flooded home, not a traditional loft. Light exposure and floor level matter enormously in a glass building, so the specific residence is the thing to evaluate. For the design-forward buyer who wants a marquee SoHo address with amenities, the building is a singular match.
What to know if you’re selling
A resale at 40 Mercer markets itself on its architecture: Jean Nouvel, the colored-glass façade, the 11-to-12-foot ceilings, and the retractable windows are durable, unrepeatable differentiators that distinguish a home here from any conventional SoHo condominium. The condominium structure widens the buyer pool to international, pied-à-terre, and investment purchasers and delivers a faster closing through a right-of-first-refusal. Pricing belongs against SoHo's high-design condominium and loft set, with floor level, light, and the presence of retractable glass driving the spread. Presentation should let the architecture lead — these residences show best when the glass, the volume, and the light are foregrounded. Marketing to the design-literate, flexibility-minded buyer this building attracts is the path to a strong sale.
