50 West 66th Street: What the Offering Plan Says About Extell's Lincoln Square Tower

Updated Oct 12, 2026 · 7 min read

50 West 66th Street is Extell's 127-residence condo tower in Lincoln Square, with a podium of apartments below a tall mechanical zone and full-floor tower homes above. Here's what the offering plan says about the finishes, the amenities, the staff, the first-year budget and the fine print, including the synagogue that shares the building.

In brief: 50 West 66th Street is a 127-residence new-construction condo in Lincoln Square, sponsored by an Extell Development Company entity and designed by SLCE Architects. The plan splits it into a "podium" of apartments on marketing floors 3 to 17 and a "tower" of larger homes on marketing floors 40 to 70, with a white-box penthouse on top. What sets it apart: a synagogue, school and event space will own a large unit in the building, the amenities run from two pools to a two-lane bowling alley, and floor names are marketing labels that don't match the building's actual stories.

What's Specific to It

• A congregation in the building: a Community Facility Unit of about 37,000 square feet is expected to go to Congregation Habonim, which plans to run it as a synagogue, religious school, pre-school and event space.
• Marketing floors vs. real floors: the plan warns that floor numbers are marketing names. Unit 66, for example, sits on the 37th construction story, and the building has 39 stories in all.
• Very tall mechanical floors: four mechanical floors are roughly 20, 64, 64 and 48 feet tall. Neighbors challenged them before the plan was filed.
• A white-box penthouse: the two-level penthouse is delivered with just one bathroom, a partial kitchen and unfinished concrete floors, for the buyer to build out.
• A third-party amenity operator: the board is expected to hire an outside operator to staff the gym, provide pool lifeguards and offer personal training for an extra fee.
• Most homes held back at launch: only 22 of the 127 residences were first offered for sale. The rest were withheld until the sponsor set prices.

50 West 66th Street rises on West 66th Street in Lincoln Square, with its residential entrance and a car drop-off on 66th Street. Its offering plan tells you who you'll share the building with, what's in the walls and what it should cost to run.

Finishes

Podium and tower apartments have separate finish schedules (compare with our NYC condo finishes guide).

Kitchen

• A full Miele suite: gas cooktop, vent hood, wall oven, speed oven, refrigerator, dishwasher and warming drawer.
• Three-bedroom podium kitchens add an under-counter Sub-Zero wine cooler. Larger homes get a 48-inch or 72-inch Miele combi-set cooktop, two wall ovens, two refrigerators, a Miele coffee system and, in the biggest tower layouts, two dishwashers.
• Painted wood cabinets and stone countertops.

Baths

• Podium: Kohler sinks with Dornbracht fittings, Toto toilets, Kallista trim in the powder room, and Zuma tubs in some primary baths.
• Tower: Waterworks sinks and tubs, Dornbracht fittings and Villeroy & Boch toilets.

See how these names rank in our bathroom brands guide.

Floors, ceilings and windows

• Engineered wood plank floors: Vintage in the podium and a thicker Grato floor in the tower, both rated for sound.
• Ceilings of about 9.5 to 12.5 feet in the podium and about 13 to 14.5 feet in tower living rooms.
• A unitized glass curtain wall with double-glazed, low-E glass, fixed panes and out-swing awning vents.

Laundry, heating and cooling

• Every residence gets a GE washer and dryer, vented through a central exhaust.
• Podium homes use water-source heat pumps in each unit. Tower homes use hot-water fan coils set in perimeter trenches for heat and ceiling fan coils fed by chilled water for cooling.
• Electricity is submetered to each unit. Cooking gas isn't, so it's paid through common charges.

Amenities

The amenities are split between the 20th floor and the sub-cellar (compare with amenities by building size).

20th floor

• A great room with seating and a bar, plus a serving pantry with a warming kitchen.
• A private conference room and a kids' lounge.
• An outdoor landscaped terrace and a pool deck with a swimming pool, hot tub, rinsing shower and sun loungers.

Sub-cellar and lower levels

• A lap pool, spa pool and fitness center with men's and women's saunas, steam rooms and locker rooms.
• A squash court, a basketball court, a fitness studio with Pilates, and a studio for training, stretching and yoga.
• A game room for about 20 people with a wet bar, a golf simulator and a two-lane bowling alley.
• A screening room for about 16, and a children's playroom for use with a parent.
• A bike room for about 66 bikes on the cellar level, first come, first served, plus a dog-washing station on the first floor.

Good to know: the board is expected to hire an outside operator to staff the gym, provide lifeguards and run programs. Year one sets aside about $300,000 for this, and personal training costs extra. Amenities were planned to open in phases, and an unfinished one isn't grounds to delay closing.

A porte-cochere on West 66th Street is for drop-off and pick-up only. You can't park there, and it can't fit a limousine. The plan lists no parking units.

Staffing and Services

The year-one budget plans a large Local 32BJ union staff:

• A live-in resident manager (in unit 4B) and three handymen.
• Concierges around the clock (about 4.2 full-time).
• Seven doormen, about 2.8 hallmen and about 2.8 package-room attendants.
• Eight porters.

Wages and benefits come to about $3.1 million, nearly half the budget. Two passenger elevators serve the podium and two serve the tower, all running 24/7, plus a service elevator. Our doorman cost guide puts these numbers in context.

Tip: until every unit is sold, the sponsor may run a smaller staff. The plan only guarantees one doorman in the lobby 24/7 during that time.

What It Costs to Run

The sponsor projected a first-year budget (March 2022 to February 2023) of about $6.3 million. Residences carry about 92% of it, and the Community Facility Unit pays about 8% of the costs the whole building shares. Here's how that works out in monthly common charges, per Schedule A:

• About $1,800 to $2,750 a month for the 22 homes first offered for sale.
• About $14,000 a month for the full-floor tower homes near the top.
• About $19,900 a month for the penthouse.

Notable lines:

• Staff: about $3.1 million.
• Utilities and insurance: about $690,000 for common-area electricity, about $330,000 for heat and hot water, and about $330,000 for insurance.
• Amenity operator: about $300,000.
• Window washing and the facade rig: about $200,000.
• Management fee: $150,000 to Extell Management Services, a sponsor affiliate. The agreement can be canceled on 30 days' notice.

Good to know: the plan sets up no reserve fund for capital repairs. You'll pay two months of common charges into working capital at closing. For why budgets like this vary so much, see why operating costs differ and our common charge benchmarks.

Fine Print Worth Knowing

• Living with a synagogue: the plan warns of possible noise from the Community Facility Unit and its outdoor courtyard. Expect more foot and car traffic on school days, the Sabbath and Jewish holidays, and possibly more police at times. The congregation may still be building out its space after you move in.
• Zoning challenges: neighborhood groups challenged the building's permits over the tall mechanical floors and the tower's floor count. The BSA denied the appeals and the courts dismissed a separate suit, but an Article 78 case was pending when the plan was filed. The plan says a successful challenge could eliminate some tower units, with deposits refunded.
• Sponsor's easement: while the sponsor owns any unit, it can use the amenities for sales events at no charge. It can also keep communications equipment on the roof or facade indefinitely.
• Storage bins: bins are sold as licenses, not deeded units, and you can only sublicense yours to another owner in the building.
• Backup power: a diesel generator on the 18th floor powers only emergency loads in most homes, such as the refrigerator, one outlet and one kitchen light. It powers the whole penthouse.
• Taxes: individual owners may qualify for the city's partial condo tax abatement. Units held by LLCs or corporations, or by anyone owning more than three units, don't qualify.

Who's Behind It

• Sponsor: West 66th Sponsor LLC, care of Extell Development Company
• Architect: SLCE Architects
• Mechanical engineer: Icor Associates
• Managing agent: Extell Management Services (a sponsor affiliate)
• Selling agent: Extell Marketing Group
• Sponsor's counsel: Kramer Levin Naftalis & Frankel
• Tax projection: Marcus & Pollack

The plan doesn't name an interior designer.

Common Questions

Does 50 West 66th Street have a pool?

Yes, two. The 20th floor has a swimming pool and hot tub on an outdoor pool deck, and the sub-cellar has a lap pool and spa pool next to the fitness center, with lifeguards expected from an outside operator.

Is the staff union?

Yes, the year-one budget assumes a Local 32BJ staff that includes a live-in resident manager, round-the-clock concierges, seven doormen and eight porters, costing about $3.1 million a year.

Who else owns part of the building?

A Community Facility Unit of about 37,000 square feet is expected to go to Congregation Habonim, which plans to use it as a synagogue, school, pre-school and event space, and which pays a share of the shared building costs.

Where this comes from: the building's offering plan (CD180494) as filed with the New York Attorney General, including its Special Risks, Description of Property, Schedule A and Schedule B. Prices are the sponsor's offering prices, not sales, and budget figures are the sponsor's first-year projections. Later amendments may change them. Updated October 2026.
