340 East 72nd Street, Upper East Side

The building is a restrained 1930 red-brick masonry house in the prevailing East Side pre-war idiom — solid, understated, built to last. What distinguishes it is the interior stock. Across 33 residences in a 16-story tower, the layouts are classic pre-war: high beamed ceilings, hardwood floors, separate entry foyers, and the gracious living-and-dining proportions of the era. Several apartments include the small bonus rooms that began as staff quarters and now serve as home offices, nurseries, or guest rooms — a flexible feature that pre-war buyers prize.

A number of homes retain wood-burning fireplaces, and the upper floors carry the best light and, on the higher levels, open outlooks toward the river. With so few apartments in the building, layouts vary meaningfully floor to floor, and the larger combinations trade as genuinely scarce inventory. This is a building for buyers who want the integrity of a pre-war home without the scale, formality, or carrying cost of an avenue trophy.

340 East 72nd Street runs as a pristine white-glove cooperative. A 24-hour door staff and a highly regarded live-in resident manager anchor the service model, supported by a renovated fitness center, a central laundry, a bicycle room, and common storage — and, distinctively for a building this size, a landscaped private courtyard garden reserved for shareholders' use. Washer/dryers are permitted within apartments. The building is pet-friendly. The cooperative permits financing of up to 50% of the purchase price, a conservative posture that keeps the building's balance sheet strong, and a flip tax of 2% applies, payable by the purchaser at closing. Purchases proceed through a board application and interview in the customary cooperative manner.

Market read. Most recent trades (2025) cleared a median $755/sf across 1 sale. Median listing discount 4.8% 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 1-01446-0038) 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.

Plan around the cooperative's financials before anything else. Financing is capped at 50%, so a substantial down payment is required, and the 2% purchaser-paid flip tax belongs in your closing budget. The board reviews a full cooperative package, and the building's conservative posture rewards strong, liquid buyers who intend the apartment as a primary residence. In exchange you get a rare combination: a true white-glove building with a live-in manager and a private garden, intact pre-war layouts, washer/dryers permitted in-unit, and a pet-friendly policy — all in a quieter, more attainable corner of Lenox Hill, steps from the East River promenade, John Jay Park, and the Second Avenue and Lexington Avenue subways.

Sell the service and the scarcity. A 33-unit white-glove building with a beloved resident manager and a planted private garden is a genuine differentiator, and the in-unit washer/dryer allowance and pet policy answer two of the most common buyer questions before they are asked. Apartments that preserve their pre-war proportions — the foyer, the separate dining room, the fireplace — present best to this audience. Because the building trades infrequently and the larger homes are scarce, a well-prepared listing tends to find motivated buyers quickly; positioning against the boutique pre-war set in the East 70s, rather than the avenue trophies, frames the value correctly.
