366 West 15th Street — The Porter House — is one of West Chelsea's most architecturally notable condominiums, standing on the southeast corner of West 15th Street and Ninth Avenue, a block from Chelsea Market and the High Line. It also carries the Ninth Avenue address 66 Ninth Avenue. The building began as a six-story yellow-brick warehouse built in 1905 for a wine importer, and its transformation in 2003 is what made it a landmark of contemporary Manhattan design.
The proposition here is architecture. In the 2003 conversion, SHoP Architects added a dramatic cantilevered four-story glass-and-zinc addition atop the historic masonry — an award-winning, widely published work that has become a reference point for warehouse conversions in the city. For a buyer who wants design pedigree paired with a prime West Chelsea location, The Porter House is a distinctive, boutique choice.
Building operations
The condominium is staffed for its boutique scale: a part-time doorman, a full-time resident manager, a rooftop lounge, a fitness room, bike storage, and storage lockers. The amenity set is efficient and well-suited to a building of this size, and the full-time resident manager keeps day-to-day operations attentive.
As a condominium, ownership is by deed. Purchases clear a condo application and the board's right of first refusal rather than a full co-op board approval, and the building offers the ownership flexibility condominiums are known for. Confirm the current pet policy, any move-in rules, and application specifics at offer stage.
Recent sales
Condominium pricing is read on a price-per-square-foot basis, and 366 West 15th trades as an architecturally notable West Chelsea condominium with strong $/sf — roughly $1,800 to $2,800 per square foot in feel, with the larger units reaching multi-million-dollar prices. With only about 22 to 24 residences, resale volume is thin, and the design pedigree supports pricing at the top of the West Chelsea conversion tier. When underwriting a purchase or a list price, capture the square footage, the floor, the exposure, whether the unit sits in the historic masonry or the glass-and-zinc addition, and renovation condition rather than relying on a neighborhood average.

What to know if you’re buying
The headline is the SHoP addition. You are buying into an award-winning, widely published contemporary work atop a 1905 warehouse — architecture that holds its value and its identity. Confirm the exact unit count and your unit's position within the building, review the resident manager's staffing and the amenity set, and read the condominium's financials and reserve. The reasons to buy are the design pedigree and the location: a block from Chelsea Market and the High Line, in one of Manhattan's most recognizable conversions.
What to know if you’re selling
The story is the architecture. The SHoP glass-and-zinc addition, the loft-scale layouts, and the corner location a block from Chelsea Market and the High Line sell to a design-literate buyer. Pricing is a unit-specific exercise on a $/sf basis: square footage, floor, light, position in the building, and condition drive the number more than any block average. We position the building's architectural pedigree and boutique scale — roughly 22 to 24 units, correcting any lower earlier estimate — and benchmark against the right comparable tier of West Chelsea condominiums.
