50 West 66th Street is the architecturally defining trophy new-construction tower on the Upper West Side and the building that, more than any other recent Manhattan commission, anchors the contemporary new-construction trophy condominium tier of the corridor. The 69-story, 775-foot tower was developed by Extell Development Company — Gary Barnett's firm, also responsible for One57 (157 West 57th Street), Central Park Tower (217 West 57th Street), One Manhattan Square (252 South Street), and the broader Extell trophy portfolio — and was designed by Snøhetta, the Basel-and-Oslo-based firm responsible for the Norwegian National Opera, the Times Square reconstruction, the September 11 Memorial Museum Pavilion, and a body of consequential international institutional architecture. 50 West 66 is Snøhetta's first New York residential commission at full scale.
Snøhetta's design at 50 West 66 produced a form structurally distinct from the conventional Manhattan luxury condominium tower idiom. The firm described the design as "sculptural excavations, evocative of the chiseled stone of Manhattan's geologic legacy" — a phrase that captures the building's defining architectural argument. The massing begins with a hand-set textured limestone podium articulated by burnished bronze and glass storefronts at street level. Above the 16th-floor mid-tower setback (which produces a shared communal amenity terrace), the tower body transitions to glass with burnished-bronze chamfered corners — and the chamfers themselves produce a vertical "zipper of loggias" running the full length of the upper volume, generating private outdoor space at over a third of the building's residences. The tower culminates in what Snøhetta has called a "warm lantern" — an illuminated bronze crown visible from miles across the Manhattan skyline.
The building's mechanical-void engineering — which elevated the upper 22 floors more than 200 feet above the 14th floor through interstitial mechanical spaces — was the subject of years of neighborhood litigation and ultimately cleared by the Board of Standards and Appeals in January 2020. The resulting tower is the tallest residential building on the Upper West Side and the most architecturally consequential new-construction residential commission in the corridor in a generation.
The building's commercial performance has matched the architectural ambition. By December 2025, the building was reported as over 70 percent sold. Unit 47E closed in October 2025 at $46.77 million — the most expensive Upper West Side residential sale of 2025 — followed by Unit 41E at $46.75 million in December 2025 and a 42nd-floor unit at nearly $45 million the same period. CityRealty has reported building average asking prices of approximately $5,139 per square foot, with recent closed sales averaging $3,300 per square foot and top-floor pricing reaching $6,400-plus per square foot. The Robb Report listing range across the building runs approximately $3.5 million through $85 million.
For buyers, 50 West 66th Street represents the architectural and operational apex of contemporary Upper West Side new-construction trophy condominium ownership: Snøhetta architectural credential, Extell development pedigree, the tallest residential position on the Upper West Side skyline, and the operational and amenity infrastructure consistent with the trophy new-construction tier.
Architecture and unit composition
The 127 residences distribute across the building's 69 stories in configurations ranging from two-bedroom apartments through full-floor penthouses. Apartment scale runs from approximately 1,300 square feet through 7,000-plus square feet for the largest combined and penthouse-tier units. Ceiling heights run up to 14 feet 6 inches; floor-to-ceiling windows define the apartment exposure throughout; custom Smallbone kitchens with Miele and Sub-Zero appliances are the standard specification.
Shamir Shah Design developed the interior architecture for the lower-floor "House" residences; AB Concept developed the interior architecture for the upper-floor "Tower" residences. The two interior treatments produce a deliberate differentiation between the lower and upper portions of the building, calibrated to the architectural distinction Snøhetta produced in the exterior tower massing.
Building operations
50 West 66 operates as a full-service condominium with 24-hour doorman, concierge, valet, porte-cochère entrance, and live-in superintendent. The 50,000-square-foot amenity package — distributed across three levels — is among the most substantial in Manhattan new-construction residential. The amenity inventory is calibrated to the trophy buyer pool: indoor saltwater lap pool, outdoor 20th-floor Sky Level saltwater pool and hot tub, full-size basketball court, pickleball court, squash court, bowling alley, golf simulator, fitness center with Pilates and training studios, screening room, infrared sauna, steam rooms, children's studio, gaming lounge, Sky Lounge with landscaped terrace and sunset bar, common dining room, spa therapy room, private storage, wine storage, bike room.

What to know if you’re buying
The Snøhetta architectural credential is structurally distinguishing. First New York residential commission at full scale; the building's exterior is among the most recognizable contemporary residential structures in the city.
The Upper West Side skyline position is structural. Tallest residential building on the Upper West Side; direct view exposure to Central Park, Hudson River, and the broader Manhattan skyline.
Apartment-by-apartment variation is meaningful. The chamfered corner geometry and the vertical loggia configuration produce significant variation in exposure, outdoor space, and view condition; recent comparables on the specific apartment line should anchor positioning.
The 50,000-square-foot amenity program is substantial. Among the most developed amenity packages in contemporary Manhattan residential.
Condominium financial mechanics apply. Right-of-first-refusal closings; typically 30–45 day pacing.
What to know if you’re selling
Marketing should emphasize the Snøhetta credential and the architectural-skyline position. These are the structural identity-anchors.
Pricing requires apartment-level comparable analysis. Substantial variation in apartment exposure, outdoor space, and view condition; recent comparables on the specific apartment line should anchor positioning.
Closing timelines are condominium-fast. 30–45 days.
