One High Line (500 West 18th Street)

The 236 residences distribute across the two towers in configurations from one-bedroom apartments through full-floor penthouses, with the largest penthouse-tier residences carrying substantial wraparound terraces. Ceiling heights are generous and floor-to-ceiling glazing defines the apartment exposure throughout.

The two towers are deliberately differentiated inside as well as out. Gabellini Sheppard developed the West Tower interior vocabulary; Gilles & Boissier developed the East Tower's. The result is that a buyer choosing between towers is choosing between two design languages as well as two exposures — a distinction that is not cosmetic and that shows up in resale positioning.

The sky bridges, the travertine, the punched-window façade and the private courtyard between the towers define the exterior identity. Terraces are unevenly distributed as a consequence of the twist, and terrace characteristics are a substantive value driver here rather than an amenity footnote.

One High Line runs as a full-service condominium: 24-hour doorman and concierge, private porte-cochère, on-site parking, and the operational depth expected in the trophy new-construction tier. The 18,000-square-foot High Line Club carries the pool, spa, fitness and lounge program, supplemented by the Faena hotel service layer.

Because the residential condominium and the hotel share a lot, a base and parts of the service infrastructure, the allocation of shared costs is worth reading rather than assuming. Ask for the current budget, the reserve position, the schedule of common-charge allocation between the residential and commercial components, and the status of any post-completion sponsor obligations. In a building delivered out of a distressed development history, the documentation of the sponsor transition is a legitimate diligence item.

This development is one of the harder addresses in Manhattan to key correctly, and it is worth being precise about what is and is not shared.

One tax lot. The entire block — both towers, the shared base, the hotel and the retail — sits on block 689, lot 7501, BBL 1006897501, condominium no. 3013. PLUTO records three structures on that lot and carries the address of record as 500 West 18th Street.

Two towers, two footprint numbers. The city's building footprint file records the two towers as separate structures with separate building identification numbers: 1089807 at roughly 390 feet to the roof, and 1090682 at roughly 301 feet. The city's address service resolves 76 Eleventh Avenue to the first and 500 West 18th Street to the second. That is a real distinction in the geographic data, and it explains why address lookups for this development return two different numbers depending on which street entrance you search.

But one building of record, and one condominium. The Department of Buildings issued a single new-building application for the project — filed at 76 Eleventh Avenue under BIN 1089807, for a 36-story, 409-foot building — and every certificate of occupancy for the development, initial and renewal, has been issued under that same number, covering the full dwelling-unit count including the hotel keys. ACRIS carries every residential unit deed in both towers under the single address 500 West 18th Street. There is one recorded declaration, one condominium number, one board of managers, one amenity program and one set of common charges.

What that means practically. The towers are two structures and one property. They are not two buildings in the sense that matters to a buyer: there is no East Tower condominium and no West Tower condominium, and a residence in either tower is a unit of the same One High Line Condominium. This page therefore covers both, and it uses 1089807 — the number on the new-building filing and the certificates of occupancy — as the building identification number of record. Anyone running an automated lookup should expect to see 1090682 surface for the 500 West 18th Street entrance and should not treat it as a second property. Anyone searching the historic record should also search "The XI" and "The Eleventh," the project's pre-2021 marketing names, and 76 Eleventh Avenue.

Ownership form: Condominium. Transfers close through a right of first refusal rather than a board interview, which keeps timelines short and predictable — plan for roughly 30 to 45 days from contract.

Pied-à-terre, subletting, LLC, trust and foreign ownership: All permitted under the standard condominium framework. Any minimum lease term or short-term-rental prohibition sits in the house rules; confirm with the managing agent.

Pets: Permitted. Confirm weight and breed limits in the current house rules.

Financing and use flexibility: Substantially greater than the equivalent uptown cooperative inventory — the condominium form supports financing levels, holding structures and use cases that tier-one Park and Fifth Avenue cooperatives do not accommodate.

Recent sales

Recent closings at this building, from The Roebling Research Library. Prices are the transfer amounts recorded with the NYC Department of Finance; apartment-level detail is checked against the building’s own file in The Roebling Research Library before publishing.

Market read. Most recent trades (2026 to date) cleared a median $3,513/sf (recorded) across 30 sales. Median listing discount 4.6% 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 1-00689-7501). 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 from recorded condo declarations and offering plans.

Confirm the address and the building number on every report. The development answers to 500 West 18th Street and 76 Eleventh Avenue, and city systems return two different building identification numbers depending on which entrance is searched. Both towers are one condominium on one tax lot.

Search the historic record under "The XI." Anything predating the 2021 sponsor change is filed under the old name.

Choose the tower deliberately. East Tower for the High Line and the city; West Tower for the Hudson and the height. Different interior architects, different exposures, different resale pools.

Evaluate the specific floor, not the tower. The rotation means apartments in the same tower at different heights face different directions.

The Faena integration is a feature and a trade. Hotel service depth in exchange for hotel presence in the building. Visit at a busy hour before deciding how you feel about it.

Read the sponsor-transition file. The project was completed out of a distressed development history under new ownership. Have counsel review the plan, the amendments and the transition documentation.

Lead with the architecture, the park frontage and the Faena layer. These are the structural identity anchors and they are what this buyer pool is shopping for.

Price the residence, not the building. Tower, floor, orientation and terrace configuration produce wide variation. A building-level per-foot figure will mislead in both directions.

Expect a design-aware buyer pool. The cohort here overlaps heavily with the international design and cultural demographic that the Faena programming draws.

Closing timelines are condominium-fast. Thirty to forty-five days from contract under typical circumstances.
