270 West End Avenue is a 1918 George F. Pelham co-op on the corner of West 73rd Street, and it is one of those Upper West Side buildings that does the quiet, important work of housing people in big, gracious pre-war apartments without making a spectacle of it. Pelham — one of the era's most prolific apartment-house architects — laid it out for space: at completion the building held a dozen seven-room apartments and a dozen ten-room apartments, the kind of room counts that defined West End Avenue's appeal to families who wanted scale without Park Avenue formality.

A century on, that DNA is the building's argument. The 36 residences run roughly five to ten rooms, from about 1,400 to 2,900 square feet, with the long entry galleries, separated wings, and generous public rooms that pre-war buyers actively seek and new construction rarely replicates. Converted to a cooperative in 1971, it has settled into the role of a stable, owner-occupied house just off Riverside Park and a short walk from Lincoln Center.

For a buyer who wants real pre-war space on a low-traffic West End corner, with full-time service and a board that has run the building conservatively for half a century, 270 West End is a serious candidate.

Architecture and unit composition

Pelham gave the building a restrained, dignified exterior: a gray-brick shaft over a rusticated stone base, with lanterns flanking the entrance to a step-up lobby. It reads as a solid, family-scaled pre-war house rather than a showpiece — characteristic of Pelham's West Side work and of West End Avenue's overall register.

The apartments are the draw. Original layouts ran to seven and ten rooms; today's mix spans roughly five to ten rooms and 1,400 to 2,900 square feet, with the high beamed ceilings, hardwood floors, and decorative detail typical of 1918 construction. The thirteen-story, 36-unit configuration keeps the building intimate, and the larger lines offer the kind of entertaining-scale public rooms that are increasingly hard to find on the West Side.

Building operations

270 West End runs as a traditional full-service cooperative: a 24-hour elevator operator and attended service, a live-in superintendent, basement storage, and a bike room. As a pre-war West Side co-op, the board maintains a conventional application-and-interview admissions process and underwrites buyers to a sound financial standard; primary-residence ownership is the norm. The building is a long-established 1971 conversion, fully sold and owner-occupied, which tends to translate into careful capital planning and predictable operations — the things that matter most in a 100-year-old building.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01164-0063) 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 building you buy for the apartment. The spread between a five-room and a ten-room home here is enormous, so identify the layout and exposure you actually need before chasing a price. Higher floors and corner lines carry better light; the largest apartments are the rarest and the most competitive when they appear. Come prepared for a conventional co-op board package and interview, plan financing to a conservative standard, and budget for standard New York co-op closing costs. A live-in super and 24-hour service are exactly what you want in a pre-war building of this age — they are a feature, not an afterthought.

What to know if you’re selling

Sell the space and the service. Pre-war room counts, the gracious public rooms, and the building's 24-hour staffing and live-in super are the differentiators against newer, smaller-roomed inventory. Price against the building's own recent trades and the comparable West End pre-war set, and stage to let the layout read — long galleries and separated wings are the reason buyers come to this corner. A board-ready buyer and a clean package keep the deal moving; in a 36-unit building, reputation travels, and a well-run sale benefits the next one.
