A Private Pricing Opinion — what your apartment at 366 West 15th Street would likely sell for today, what it costs to sell, and what you’d walk away with — reviewed personally against condition, exposures, renovation quality, and the competition actually on the market.
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.
Architecture and residences
The building's story is the addition. The 1905 yellow-brick warehouse was converted in 2003 with a cantilevered four-story glass-and-zinc volume designed by SHoP Architects — a bold contemporary gesture that hovers over the original masonry and has been widely published and celebrated. The result is a 10-story building of approximately 22–24 residences, with units ranging roughly 900 to 3,400 square feet. The mix rewards buyers who want loft-scale living with a genuine architectural signature.

Recent sales
366 West 15th trades as an architecturally notable West Chelsea condominium. 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.

Market read. Most recent trades (2023) cleared a median $1,300/sf (floor-adjusted) across 1 sale. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 2.2% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

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.

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
