330 West End Avenue is a small, characterful pre-war cooperative — a 1917 red-brick building of just 21 homes, converted to cooperative ownership in 1981, sited near the corner of West 76th Street on the lower run of West End Avenue. What sets it apart from the avenue's larger pre-war stock is its intimacy and its unusual plan: simplex apartments on the A-line, duplexes on the B-line, and a single duplex penthouse crowning the building. For buyers who want a true pre-war home with the flexibility and privacy of a duplex, in a building small enough that every owner knows the super by name, it is a genuinely distinctive option.
The duplex line is the building's signature. Each B-line home spans two floors and includes its own enclosed private "green room" — an interior garden-room feature that is rare in pre-war New York and that gives these apartments a quality of light and a sense of separation between living and sleeping levels that flats simply cannot offer. Add a washer/dryer in every apartment — uncommon in pre-war cooperatives, where in-unit laundry is often restricted — and the building punches well above its modest profile.
Architecture and unit composition
The exterior is restrained, handsome pre-war: red brick over a masonry base, mid-block in scale, fourteen stories rising to a penthouse level. The most memorable architectural moment is interior — an angled, step-up lobby that reflects the building's unusual footprint and gives the entry a quirk that residents tend to remember fondly.
The 21 residences divide cleanly. The A-line, running floors two through twelve, holds simplex apartments. The B-line — on floors three, five, seven, nine, and eleven — holds the duplexes, each two stories with its own enclosed green room. The 14th floor contains a single duplex penthouse, the building's crown. Across the board the homes carry pre-war proportions — high ceilings, hardwood floors, proper foyers — and every apartment has its own washer/dryer, a meaningful convenience that distinguishes this building from most of its neighbors.
Building operations
330 West End Avenue is run as a tight, well-maintained boutique cooperative. A live-in superintendent looks after the building, and the in-unit washer/dryers reduce the load on common laundry that a building this size would otherwise carry. There is no full-time doorman — standard and expected for a 21-unit pre-war — which keeps monthly carrying costs reasonable while preserving the building's private, low-key character.
The board's posture is unusually accommodating for a pre-war cooperative: the building is pet-friendly and permits pied-à-terre ownership, two policies that materially widen the buyer pool relative to stricter neighbors. Purchases are subject to cooperative board review and a financing posture consistent with the corridor; subletting is governed by board policy. The combination of duplex layouts, in-unit laundry, pet and pied-à-terre flexibility, and a small, manageable building is the core of 330 West End Avenue's case.

Facade safety — Local Law 11
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.

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 board-approval cooperative, so prepare a full application and an interview — but one with a friendlier policy stance than much of the avenue, given the pet and pied-à-terre allowances. Decide first whether you want a simplex or a duplex; the duplexes with their private green rooms are the building's distinguishing product and the harder to find. The in-unit washer/dryers and the small scale are real lifestyle advantages, and the lower West End location puts the 1/2/3 trains, Riverside Park, and the Lincoln Center corridor within easy reach. We help buyers read the financials, weigh the simplex-versus-duplex value, benchmark the price, and assemble a board package that presents cleanly.
What to know if you’re selling
The selling story is differentiation: a boutique 1917 cooperative with duplex homes, private green rooms, in-unit laundry, and a pet- and pied-à-terre-friendly board — a package very few pre-war buildings can match. Lead with whatever sets the specific apartment apart — the duplex's two-floor flow and green room, or a simplex's light and layout — and market the building's accommodating policies, which expand the buyer pool. Pricing belongs against the boutique pre-war cooperatives on the lower West End and Riverside blocks rather than the large full-service buildings. With turnover this thin, a well-prepared listing benefits from scarcity. We position the home to the right buyer and manage the board timeline so the deal closes without surprises.
