150 East 23rd Street

ODA's design is the building's signature. The lower floors present as a clean limestone-and-glass shaft; higher up, the massing fractures into faceted, angled planes that read differently from every approach and culminate in the tapered crown. It is contemporary without being a plain glass box — a deliberate piece of architecture on a block that had little of it.

Inside, the 51 residences run from one to three bedrooms, scaling up to three expansive penthouses at the top of the building. New construction here means contemporary ceiling heights, floor-to-ceiling glass, open kitchens, and modern mechanical systems throughout, with in-unit laundry standard. The faceted upper floors yield distinctive corner exposures and private outdoor space on the higher homes. Layouts favor open living and entertaining, with the penthouses commanding the widest light and the best views toward both parks.

For a building of this size, the amenity program is generous. The headline is the outdoor heated swimming pool — a true rarity at this scale in Gramercy — paired with a rooftop sundeck and grill, a state-of-the-art fitness center, a children's playroom, and a resident lounge, all behind a 24-hour attended lobby with a live-in resident manager.

The location supplies the rest. Gramercy Park's gated green sits a few blocks south, Madison Square Park and its restaurant row a few blocks north, and the Flatiron and Union Square dining-and-retail districts are an easy walk in either direction. With multiple subway lines at 23rd Street, the building is a genuinely convenient home base for buyers who want amenities, quiet residential streets, and full transit access in one address.

As a condominium, Celeste has no co-op board admission; a purchase runs through the condominium's application and right-of-first-refusal process rather than a co-op board package and interview. Confirm financing, leasing and ownership-entity rules in the current declaration, bylaws and house rules. For buyers who want a modern home in Gramercy without a co-op board, that is the core of the building's appeal.

Pricing sits in the boutique new-condominium tier — entry one-bedrooms anchoring the bottom and full-floor penthouses at the top — and comparable analysis belongs against the newest condominium inventory around Gramercy and Madison Square, not the pre-war stock nearby. The residences were offered under a condominium plan accepted for filing by the New York State Attorney General; we help buyers read the plan, benchmark the pricing, and structure the deal.

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 $1,872/sf (floor-adjusted) across 2 sales. 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 4.3% 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 1-00878-7502; each condominium apartment is its own tax lot). 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.

The architecture and the amenity package are the marketing core. ODA's faceted tower and, above all, the outdoor heated pool are durable differentiators that distinguish a resale here from anything in the surrounding pre-war inventory. Benchmark to new-construction condominiums around Gramercy and Madison Square, not the older co-ops — the building debuted in the top tier of the immediate area and should be positioned there. Closing mechanics are condominium-standard: a resale clears through a right-of-first-refusal rather than a board process. The 51-home count does not establish current supply or a resale advantage; check active listings and recorded turnover before using scarcity in the pricing argument.
