123 West 74th Street

Bagge & Sons designed 123 West 74th Street in the restrained Renaissance Revival idiom that suited the Upper West Side's better side-street houses — a masonry elevation with a defined base, a quiet middle, and modest cornice detailing, scaled to read as part of a continuous streetwall rather than as a standalone tower. The nine-story building has roughly 54,000 square feet of gross building area across 42 apartments, a ratio above 1,200 square feet per unit. That includes common and service space and does not establish average interior size or layout; confirm dining rooms, foyers and bedroom wings from the specific apartment’s plans.

Apartments range from gracious one- and two-bedrooms to larger three-bedroom homes, many retaining hardwood floors, high ceilings, beamed details, and the deep proportions characteristic of the period. Original layouts vary floor to floor; over a century of ownership, individual units have been renovated to differing degrees, so the building offers both turnkey homes and apartments with renovation upside.

123 West 74th Street operates as a traditional self-managed-feel pre-war co-op with a live-in superintendent and porter staff handling day-to-day maintenance, package handling, and the central laundry. The building maintains private storage and a bicycle room, and access is by elevator with video intercom security rather than a 24-hour doorman; assess costs from current maintenance, assessments, reserves and included services rather than infer efficiency from staffing or unit count. Pets are permitted subject to board approval, in keeping with the building's family-and-long-term-resident character.

The cooperative has 42 apartments across nine floors. As with any pre-war cooperative, prospective purchasers should review the building's financials, reserve posture, and any planned capital work as part of the board package process.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01146-0018). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. 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.

This is a co-op, so a purchase runs through a board application and interview, and buyers should plan for the financial scrutiny that comes with it — a clean financial picture and reasonable post-closing liquidity matter. Pre-war co-ops of this vintage limit financing — here the board requires a minimum 33% down payment (financing up to 67%); pied-à-terre and investor purchases are generally discouraged in favor of primary-residence owners. Pets are allowed with board approval, and in-unit washer/dryers are permitted. Buyers should weigh the value equation carefully: pre-war space and a historic-district block at a price point below the avenue addresses, in exchange for the board process and the self-service (rather than full-doorman) operation.

The right buyer here is someone who values square footage, architectural character, and a stable long-term community over amenities and lobby theater — and who appreciates that the historic-district protection around the building is a durable asset.

The selling case is built on the pre-war fundamentals: real layouts, high ceilings, a protected historic-district block, and a walk-everything Upper West Side location. Renovated apartments with strong light show best and justify the building's top pricing; sellers of original-condition units should price to renovation reality and target buyers looking for value and upside. Because the building trades infrequently, positioning against the right comparable set — nearby pre-war side-street co-ops rather than amenity-rich towers — is essential to setting expectations and timing. A board-ready buyer is as important as the price; we screen for financial qualification early to protect the deal through the application.
