127 West 79th Street (The Clifton House)

Gronenberg & Leuchtag organized the building as a 15-story palazzo: limestone for the first two floors, beige brick above, ornament concentrated where the street sees it. Rope-twist columns flank every other pair of third-floor windows, and the facade carries decorative balconies and a restrained cornice. Inside, the apartment-hotel origins mean efficient pre-war layouts — studios through two-bedrooms predominate, with foyers and proportions that read larger than their square footage — and the combination inventory supplies the building's three-bedroom-scale homes. High floors on the south side pick up open light over the lower streetwall opposite; east lines angle toward the museum and park end of the block.

Full-service co-op operations: 24-hour doorman, live-in superintendent, central laundry, bike room, and a common roof deck. Gas and electric are included in maintenance per listing records — a real factor when comparing monthly carry against buildings that bill utilities separately — and through-wall air conditioning is permitted, which matters in a historic-district building where window-unit and facade rules can otherwise constrain cooling. There is no garage and no fitness room per architectural records; compare actual operating costs and included services before inferring lower overhead from those absent amenities. The offering plan is on file in The Roebling Research Library.

Market read. $/sf is measured on the latest sales with reliable square footage (2025): a median $1,064/sf (floor-adjusted) across 2 sales. The building has traded as recently as 2026. Median listing discount 1.1% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01210-0019). 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.

The sublet posture defines the buyer profile. Listing records indicate subletting is not permitted, and pied-à-terre ownership runs case-by-case with board approval. This is a primary-residence building first — investors and flexibility-driven buyers should confirm current policy with the managing agent before offering.

Bundled utilities change the carry math. Gas and electric inside maintenance means the sticker maintenance overstates the comparable cost against buildings that bill separately. Run the True Monthly Carrying Cost Calculator on a like-for-like basis.

Verify any proposed combination. The historical and current unit counts do not establish approval precedent. Review specific board approvals, DOB records, current alteration requirements and applicable LPC review with the project team before assuming adjacent apartments can be combined.

Financing and fee terms are thinly documented publicly. The financing maximum and any flip tax should be verified with the managing agent at offer stage; we confirm current terms against board documents during diligence. Run the Co-op Board Qualification Calculator before you offer.

The block is the upside. West 79th between Columbus and Amsterdam carries museum-park geography at its east end, the crosstown bus at the corner, and two subway corridors within three blocks. Spend time on the block at different hours — it is among the most complete on the West Side.

Present service, location and apartment dimensions. Buyer priorities vary; document the specific features and actual costs. State the 24-hour door, the bundled utilities, and the roof deck plainly — and frame maintenance against utilities-separate comparables so buyers read it correctly.

Condition drives the spread. With apartment-hotel-origin layouts, renovated units clear at meaningful premiums over estate condition. Price honestly to the renovation math — run the Renovation Cost Calculator against your asking strategy.

Document the building for buyers' counsel. The offering plan on file in The Roebling Research Library, plus current financials from the managing agent, shortens attorney diligence. We provide the underlying documents to serious buyers early, which protects deal velocity.
