10 West 55th Street (18W55)

Morris Adjmi's design is contextual rather than flashy: a masonry-and-glass tower scaled to its block, detailed to sit among the older Fifth Avenue stock rather than shout over it. The result is a building that reads as deliberate and durable — the opposite of a generic glass slab — while delivering the floor plates and window walls of new construction.

The residential program spans the full size range, from studios through three-bedroom homes, with the smaller units making up the bulk of the count and larger layouts on the upper floors. New construction here means tall ceilings, full-height glazing, modern kitchens and baths, and the air-handling and acoustic performance that older buildings on these blocks rarely offer. The spread of layouts gives the building a wider range of apartment sizes than a typical Midtown trophy tower.

10 West 55th runs as a full-service rental building: an attended lobby with door staff, a fitness center, and resident lounge and service spaces built into the program. The apartments are leased, so condominium terms — financing, pied-à-terre and investment ownership, subletting and resale through a right-of-first-refusal — do not apply here. Rents, fees, and lease terms come from the building's current leasing information; prospective tenants should confirm them with the leasing office.

Recent sales

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01270-0044; each condominium apartment is its own tax lot). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price.

There is no individual apartment purchase at 10 West 55th today: the developer markets the building as 18W55, a rental, and announced the opening of 97 rental residences in November 2025. A prospective tenant should work from the current leasing information — rent, lease term, fees, and building policies — and confirm it with the leasing office. A buyer who wants a new Midtown condominium should benchmark against the condominiums in the comparison set below, and should not treat this building as condominium inventory unless a conversion or offering plan is documented.

There is no individual apartment resale market at 10 West 55th: the apartments are leased, and no condominium offering or individual apartment sales are documented at the project, which opened in 2025. Transfers recorded against the tax lot before the opening are land or building transfers, not apartment sales. An owner selling a new condominium nearby should benchmark to other new and recent condominiums in the Midtown / Fifth Avenue core, not to this building.
