406 West 45th Street, the Thorndale, is a boutique condominium carved from an early-1900s low-rise masonry building on a residential block of Clinton, the western edge of Hell's Kitchen. The 2006 conversion turned a six-story structure with carriage-house-era bones into 21 residences, keeping the intimate scale and street presence of the original while delivering contemporary condominium ownership behind it. It is a small, owner-focused building on a quiet mid-block stretch a short walk from Ninth Avenue's restaurant row and the Midtown West office core.
The appeal is a genuinely boutique condominium in a neighborhood that skews toward larger rental towers and pre-war walk-ups. Buyers here get fee-simple ownership, the light closing process of a condominium, and the flexibility to hold, sublet, or use a residence as a pied-à-terre — all in a 21-home building where the operating profile stays lean and the common areas are shared by a small number of households.
Building operations
The Thorndale operates as a boutique condominium: common areas and building systems are maintained through the common charges, with staffing scaled to a 21-home building — typically a superintendent supported by a virtual-doorman entry system rather than a full-time attended lobby. As a condominium, the building offers deeded, fee-simple ownership. There is no co-op board interview; a purchase clears through the condominium's right of first refusal, and financing is arranged directly between the buyer and lender without co-op-style caps. Pied-à-terre use, investment ownership, and subletting are permitted under the bylaws, and the building is generally pet-friendly. Any transfer fee and the specific sublet terms should be confirmed at offer stage.
Recent sales
Condominium pricing at 406 West 45th Street is read on a per-square-foot basis, not against a neighborhood average. This is a 21-unit boutique building, so resale volume is thin by nature, and pricing is driven by the specifics of each home — floor, exposure, layout, ceiling height, and any private outdoor space — rather than by a single building-wide number. A residence should be underwritten on its own footage and condition against the right comparable tier, not on the Clinton or Hell's Kitchen average.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01054-7502) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk.

What to know if you’re buying
The buying path is a condominium path. There is no board interview; you clear the condominium's right of first refusal, and you arrange financing directly with your lender. Diligence centers on the offering plan and any amendments, the building's financial statements and reserve position, the bylaws and house rules, and — because this is a conversion of an older structure — the age and condition of the building's systems and any capital plans. Within the building, floor, light, layout, and outdoor space drive value.
The reasons to buy are the combination of scale, structure, and location: a genuinely boutique condominium with fee-simple ownership and full use flexibility, on a quiet Clinton block minutes from Midtown West's jobs, transit, and Ninth Avenue's dining.
What to know if you’re selling
The story is scarcity of a particular kind: a small, character-rich condominium conversion in a corridor dominated by larger rental product and walk-ups. Pricing is apartment-specific — footage, floor, light, and condition — so the right approach is to position the individual home's narrative and benchmark it against the correct comparable tier of boutique condominium homes nearby, rather than against the broad neighborhood number. With only 21 residences, comparable supply is limited, which works in a well-prepared seller's favor.
