90 Lexington Avenue

The building's bones are mid-century: a Carson & Lundin structure whose solid floor plates and efficient massing translated cleanly into residential use. The 2015 conversion modernized the envelope and the interiors while keeping the building's straightforward, dignified scale. Workshop/APD's interior program gives the residences a coherent contemporary-luxury finish, a consistency that distinguishes a planned conversion from a piecemeal one.

The 53 residences at 90 Lexington span fourteen stories in a range of layouts, from one-bedroom homes to larger family residences and penthouse units. As a conversion of a substantial mid-century structure, the apartments offer efficient, well-proportioned layouts with the light and outlook that the building's corner position affords; upper-floor homes capture the best of both. Penthouse and high-floor residences command the building's premium.

88 & 90 Lex runs as a full-service condominium with a notably deep amenity set: a 24-hour doorman, a resident manager, a private garage, a fitness center, an indoor swimming pool with a Jacuzzi, a steam room, and a sauna — a wellness-and-convenience package that few buildings in the immediate area match, especially with on-site parking. Common charges reflect that staffing and the amenity upkeep; real estate taxes are billed per unit in the standard condominium structure.

The condominium format has no co-op board admission: purchases clear through a right-of-first-refusal rather than a board interview. Financing, pied-à-terre, trust, LLC and investment ownership, subletting and pet specifics follow the condominium's governing documents and are confirmed through the managing agent.

Market read. Most recent trades (2026 to date) cleared a median $1,933/sf (floor-adjusted) across 3 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 3.0% 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 1-00882-7502; 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 building offers full-service living and a NoMad amenity package. You get a 24-hour doorman, an indoor pool, a fitness center, a sauna and steam room, and — uncommonly for the neighborhood — a private garage, with financing and purchase requirements governed by the documents and lender; compare prices and total carrying costs with the specific new-construction alternatives. The trade-offs are that this is a mid-century conversion rather than a glass tower: the layouts are efficient and the views are city-scaled rather than sweeping, and floor level and exposure drive the difference between lines. Buyers who value amenities — especially the pool and the parking — the central location, and condominium flexibility over trophy views will find the building well-matched; upper-floor and penthouse homes are worth targeting for light and outlook.

A resale at 88 & 90 Lex sells on its amenities, its location, and its condominium ownership. The wellness package — the indoor pool, the gym, the sauna and steam room — and the rare private garage are the headline draws, and the NoMad location backs them up. The condominium structure means a purchase runs through a right-of-first-refusal rather than a co-op board process. Pricing belongs against the contemporary and converted condominium set in NoMad and the East 20s, with floor level and exposure driving the spread. Presentation should foreground the amenities, the light, and the convenience of the location and parking. Marketing to the amenity-focused buyer NoMad attracts is the path to a clean sale.
