The Clayton is a 1940 corner cooperative at Amsterdam Avenue and West 92nd Street — a low-rise, red-and-brown brick apartment house from the tail end of the prewar era. It sits at the center of one of the Upper West Side's most livable residential pockets, a short walk from Central Park, Riverside Park, and the 1/2/3 subway lines at 96th and 86th Streets. The building was developed as part of The Clayton, a small residential group that includes a paired building on West 92nd–93rd Street.
The Clayton trades as a cooperative, and its appeal is that of a well-located, human-scaled prewar co-op: a doorman-attended lobby, quiet residential blocks, and cooperative pricing that typically sits below the condominium inventory nearby. The trade-off is the cooperative framework — a board interview, board-governed financing, and board-approved subletting. For a resident buyer who values a boutique-scale building in a prime, low-key Upper West Side location, The Clayton is a natural fit.
Architecture and unit composition
The 1940 building is a six-story late-prewar apartment house in red-and-brown brick on the corner of Amsterdam Avenue and West 92nd Street. Its low-rise scale keeps it in character with the surrounding residential blocks, and the corner siting gives many apartments dual exposure and good light.
Because pricing at a cooperative is customarily read on a per-room basis, the building's prewar layouts are the natural unit of comparison. The unit mix runs from prewar studios and one-bedrooms to larger family layouts. Condition varies apartment to apartment with renovation history; specific room counts and configurations should be confirmed for each apartment during walkthrough.
Building operations
The Clayton operates as a cooperative with an attended lobby, central laundry, and resident storage. As a cooperative, monthly maintenance covers the building's underlying operating costs and a portion of the underlying mortgage and property taxes.
Buyers should review recent financial statements, board minutes, and any reserve study during due diligence, and confirm the building's pet, sublet, financing-maximum, and flip-tax policies with the managing agent at offer stage.
Recent sales
The Clayton trades as a boutique prewar Upper West Side cooperative, and pricing is best read on a price-per-room basis against the corridor's other prewar co-ops. Value is driven by exposure (corner versus interior lines), floor height, room count, and renovation condition, with cooperative pricing generally sitting below the condominium inventory nearby. Apartment-level closing detail should be sourced from public records for full transactional context, and pricing should be validated against the most recent comparable sales at the time of offer.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01223-7501) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage on co-ops is not officially recorded, figures shown are approximate.
What to know if you’re buying
This is a cooperative — plan for the board. A board interview is required, financing is capped by the board, and subletting requires board approval. Confirm all policy specifics with the managing agent at offer stage.
The corner site drives light. The Amsterdam/West 92nd corner gives many lines dual exposure; interior lines present differently. Walk the specific apartment.
Boutique scale is the character. The low-rise building offers a more intimate, quieter posture than the corridor's larger buildings.
Location is a durable asset. Central Park, Riverside Park, and the 1/2/3 lines are within an easy walk.
Model the full carry — monthly maintenance plus any assessment — and verify board policy (pets, sublet, financing maximum, flip tax) with the managing agent.
What to know if you’re selling
Lead with location and scale. A boutique prewar cooperative in a prime, low-key Upper West Side pocket appeals to resident buyers seeking quiet and convenience.
Set expectations on the board process. A strong board package and pricing to the cooperative buyer pool shortens the timeline.
Pricing requires apartment-level context. Comparable sales vary by line, floor, exposure, and condition.
Closing timelines are cooperative-standard. Plan for roughly 6 to 10 weeks from contract through board approval to closing.
