321 West 78th Street sits on one of the most charming residential blocks on the Upper West Side — a tree-lined townhouse street between West End Avenue and Riverside Drive, a short walk from Riverside Park. Built in 1925 and designed by Sommerfeld & Sass, the nine-story building is a graceful pre-war: red brick and limestone, with three-story pilasters rising to frame a canopied entrance. On a corridor where the celebrated full-service towers can feel imposing, 321 West 78th is the human-scaled alternative — a doorman pre-war on a quiet block, close to the river.

Built as a rental and converted to cooperative ownership in 1979, the building has been a share-and-board co-op for more than four decades. What makes it stand out among pre-wars is its unusually accommodating house rules: it is pet-friendly, permits washer/dryers in apartments, and allows pied-à-terre purchases with board approval — a combination of flexibilities that many older West Side co-ops still resist, and one that materially widens the building's appeal.

Architecture and unit composition

The building is a well-mannered example of mid-1920s Upper West Side design. The red-brick façade is detailed with limestone, and the entrance is framed by pilasters that rise three stories and sheltered by a canopy — a dignified, restrained street presence that fits the townhouse block rather than overpowering it. At nine stories, the building keeps a low, neighborly profile that the side-street setting rewards.

The 56 apartments carry the pre-war virtues — solid room proportions, real foyers, good light — on a comfortable scale. Because the building permits washer/dryers, owners can install in-unit laundry, a convenience that older pre-wars frequently forbid and that buyers increasingly require. A renovation and alteration cycle in 1987 modernized common systems while preserving the building's character. The combination of pre-war bones and contemporary-friendly rules is the building's core value.

Building operations

321 West 78th Street is run as a full-service cooperative with a full-time doorman and a live-in superintendent. On-site amenities include a central laundry room, common storage, and bicycle storage. The house rules are notably accommodating: the building is pet-friendly, permits washer/dryers in apartments, and allows pied-à-terre purchases with board approval. On the financial side, the co-op permits financing up to 75% of the purchase price and charges a 2.5% flip tax at closing. That flexible posture — doorman service paired with modern-living rules — is unusual for a pre-war of this vintage and is a genuine differentiator on the corridor.

What to know if you’re buying

The house rules are the differentiator. Pet-friendly, washer/dryers permitted, and pied-à-terre purchases allowed — for a 1925 co-op, that flexibility is rare and valuable. If in-unit laundry or a part-time home is a requirement, this building accommodates where many neighbors will not.

The terms are reasonable. Financing to 75% and a 2.5% flip tax are standard for a full-service pre-war; budget the flip tax as a seller cost at exit.

Buy for the block. The tree-lined townhouse setting between West End and Riverside, a short walk to Riverside Park, is a durable amenity in itself — quiet, central, and close to the river, with the doorman service that supports value.

What to know if you’re selling

Lead with the flexibility. A pet-, washer/dryer-, and pied-à-terre-friendly pre-war reaches buyers that stricter co-ops turn away — make those rules a headline, not a footnote.

Position the block and the service. The townhouse-street location near Riverside Park and the full-time doorman are the lifestyle case; pair them with the pre-war room proportions in the marketing.

Benchmark to flexible doorman pre-wars in the West 70s. Comparable analysis belongs against other full-service co-ops on the prized side streets between West End and Riverside, not against generic inventory — the rules and the location set the building's tier.
