1091 Lexington Avenue sits at the center of Lenox Hill, on Lexington at East 77th Street — one of the most consistently in-demand stretches of the Upper East Side. The 6 train at the 77th Street station is essentially at the door, the Madison Avenue retail and gallery corridor is a block west, and the cross-streets connect quickly to Central Park and Museum Mile. It is a quintessential "live everywhere on foot" Upper East Side address, with neighborhood retail at the building's own base and the restaurants and groceries of upper Lexington and Third Avenue all within a few hundred yards.
The building belongs to the late-1950s postwar cooperative generation that reshaped the avenues of the Upper East Side. As Lenox Hill's older low-rise stock gave way to taller full-service buildings, developers built apartment houses designed around efficient layouts, full staffing, and the practical needs of a residential community rather than the ornamental ambitions of the pre-war era. 1091 Lexington is a clean example: 16 stories, roughly 95 apartments, and a scale that supports a real staff while keeping turnover and anonymity low.
For a buyer who wants a central Lenox Hill address with a postwar floorplan — larger windows, efficient room flow, the conveniences of mid-century construction — at pricing typically more accessible than the pre-war and Park-block tiers nearby, 1091 Lexington occupies a useful niche in the corridor.
Architecture and unit composition
The exterior is characteristic of refined late-1950s Upper East Side construction: a brick body on a limestone-trimmed base, organized as a clean, vertical facade without heavy ornament. The era's design emphasis was on the apartment interior and on light, not on facade decoration; the avenue base carries ground-floor retail in keeping with Lexington's mixed-use character.
Across the 16 stories, the roughly 95 apartments span a range of configurations, from compact one-bedrooms to larger two- and three-bedroom homes; some lines run to substantial three-bedroom, three-bath layouts in the 2,000-plus-square-foot range. Postwar signatures recur throughout: efficient room flow, generous closet runs, and large windows. Ceiling heights follow the postwar norm — typically below the pre-war maximum but paired with brighter, more practical interiors. Higher floors gain open exposures over the surrounding low- and mid-rise blocks; light and outlook improve materially with altitude on this stretch of Lexington.
Building operations
1091 Lexington Avenue operates as a full-service postwar cooperative with door staff, elevator service, a live-in superintendent, central laundry, and private storage. The roughly 95-apartment scale supports a stable staffing model and the kind of low-key, residential operation that defines the better Lenox Hill postwar buildings.
The building maintains a no-pets policy, with service animals accommodated as required by law. As at most postwar co-ops on the avenue, the proprietary lease and house rules govern financing allowance, sublet, and pied-à-terre terms; a buyer's team reviews those documents as part of the board package.

Facade safety — Local Law 11
The latest available FISP filing classified the facade as Safe — no repairs were required at that inspection. Facade inspections run on a fixed five-year cycle; future inspection, repair, and any assessment decisions remain building-specific.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01411-0053) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage on co-ops is not officially recorded, figures shown are approximate.
What to know if you’re buying
Central Lenox Hill location is the foundation. The 77th-and-Lexington position, with the 6 train at the door, is among the most walkable and transit-convenient on the Upper East Side.
Postwar plans differ from pre-war. Expect larger windows and efficient flow, with ceiling heights generally below the pre-war maximum — a practical, light-filled alternative to the corridor's pre-war stock.
Pricing is typically more accessible than the Park-block tier. Buyers can secure a strong Lenox Hill address here at per-square-foot pricing below Fifth and Park.
Note the pet policy. This is a no-pets building; animal-owning buyers should weigh that early.
Underwrite the apartment, not just the building. With a range of configurations across 16 floors, line- and floor-level comparable analysis matters more than building-wide averages.
What to know if you’re selling
Lead with location and convenience. Central Lenox Hill, walkability, and the 6 train at the corner are the headline for the building's buyer pool.
Price at the line and floor level. Exposure and altitude drive value dispersion; building averages understate the spread.
The full-service operation is a selling point. Door staff and a live-in superintendent distinguish the building within the postwar Lenox Hill set.
Closing timelines are co-op standard — generally 6–10 weeks from contract to closing, subject to board package and approval pace.
