511 West End Avenue is the kind of building that defines the corridor: a 1926 pre-war cooperative anchoring the southwest corner of West 84th Street, full-service, generously laid out, and protected within the Riverside–West End Historic District. West End Avenue is Manhattan's great residential boulevard — wider and quieter than Broadway, set one block in from Riverside Park, and lined almost entirely with substantial pre-war co-ops of exactly this vintage. 511 sits comfortably among them.

The building's appeal is the appeal of the corridor distilled. These are apartments built for a different scale of living — high ceilings, real entrance galleries, separate dining rooms, and the kind of room count that has become difficult to reproduce. With only two apartments sharing a landing on most floors, the residences carry a near-private feel, and the full-service staffing — a 24-hour doorman, a live-in resident manager, and a daytime porter — runs the building at the standard buyers expect on West End Avenue.

Architecture and unit composition

511 West End Avenue reads as a textbook example of the avenue's 1926 cooperative stock: a limestone base giving way to a brick shaft, restrained classical detailing, and a massing built for light and air rather than spectacle. The configuration — two homes per landing on most floors across 16 stories — produces large, gracious layouts with the entrance foyers, formal dining rooms, and well-proportioned bedrooms that pre-war buyers come to the corridor to find. A number of the upper homes capture open city and partial river exposures.

The building carries a children's playroom, central laundry, a bicycle room, and private resident storage — the practical amenity set that matters most to the families who anchor West End Avenue. Its position within the Riverside–West End Historic District protects both the building's own façade and the character of the blocks around it.

Building operations

511 West End Avenue is run as a full-service cooperative. A 24-hour doorman and a live-in resident manager are supported by a daytime porter, and the building maintains the playroom, laundry, bike room, and storage on premises. Financing is permitted up to 65% of the purchase price, and a modest flip tax assessed on a per-share basis is paid at closing. The building is pet-friendly. As with most pre-war West End Avenue cooperatives, the board reviews purchases through a full application and interview, and primary residence is the norm — the building is end-user-oriented rather than an investor's pied-à-terre market.

What this means for you

Safe to live in today — but the last inspection flagged repairs that are due on a deadline, so facade work and its cost are coming. Whether that’s a real concern depends on the scope, the timing, and how the building plans to pay for it — reserves or an assessment — which is exactly what we’d dig into for you.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01246-0036) and verified listing data.

Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price.

What to know if you’re buying

The building rewards buyers who want a true pre-war home on West End Avenue. Financing is capped at 65%, so plan for a down payment of at least 35% plus closing costs and reserves the board will expect to see. A per-share flip tax is paid at closing — budget for it in your numbers. The building is pet-friendly. Expect a full board application and interview: pre-war West End Avenue boards look closely at post-closing liquidity and debt-to-income, and the process is part of buying here. Primary residence is the expectation; this is not a pied-à-terre or investor building. The reward is space — the layouts here are larger and better-proportioned than almost anything in newer construction at comparable price.

What to know if you’re selling

Lead with the layout and the address. A well-proportioned pre-war apartment with an entrance gallery and a real dining room, in a full-service co-op on West End Avenue inside the historic district, is exactly what corridor buyers are searching for. Price to the West End Avenue pre-war comparison set — the relevant benchmarks are the other full-service 1920s co-ops on the avenue between the 80s, not Broadway condos or newer product. Prepare the buyer for the board. A clean, fully documented package moves faster through a pre-war board; we help sellers vet buyers for board-readiness before an accepted offer so a deal doesn't stall at the application stage. The building's two-per-landing privacy and full staffing are selling points worth foregrounding.
