70 East 77th Street is a quintessential Lenox Hill pre-war cooperative — a nine-story, red-brick apartment house set mid-block between Madison and Park Avenues, the address that defines the heart of the Upper East Side. Built in 1917, it belongs to the first wave of the neighborhood's purpose-built apartment houses, and it has the hallmarks the era is prized for: large, gracious layouts, real architectural detail, and the kind of quiet, between-avenues siting that buyers on these blocks specifically seek.

The exterior is more refined than its modest height suggests: a two-story terracotta entrance surround, stringcourses, lunettes above the windows, and a scalloped cornice give the building a finely worked face. With only 30 residences across nine floors, it is genuinely boutique — large apartments, few neighbors, and the settled, owner-occupied character that comes with a small shareholder base. The roughly 2,150-square-foot-per-unit average reflects substantial homes rather than carved-up plans.

For buyers, the case is the classic Upper East Side one: an intimate, full-service pre-war cooperative with wood-burning fireplaces and pre-war scale, on a prime Madison-to-Park block within walking distance of Central Park, the museums, and the neighborhood's best retail.

Architecture and unit composition

The building reads as a well-detailed example of the 1917 Lenox Hill type: a red-brick mid-block apartment house with a two-story-high terracotta entrance surround, stringcourses banding the façade, lunettes above the upper windows, and a scalloped cornice crowning the composition. It is restrained but considered — the work of an era that expressed quality through proportion and crafted detail rather than ornament for its own sake.

Inside, the 30 residences carry pre-war scale: high ceilings, well-proportioned rooms, and the gracious entry-and-gallery planning of the period. A standout feature is the presence of wood-burning fireplaces in apartments — an increasingly rare amenity in Manhattan and a genuine draw for buyers of pre-war homes. The mid-block siting between Madison and Park means light from the street and quiet interiors away from avenue traffic. Layouts skew to family-scaled two-, three-, and four-bedroom configurations consistent with the building's large per-unit average.

Building operations

70 East 77th Street operates as a full-service pre-war cooperative scaled to its size: a full-time doorman, a bicycle room, and basement storage. For a 30-unit building, that staffing model delivers attentive service and security without the carrying costs of a large amenity plant — exactly the lean, well-run profile that long-term Upper East Side owners prefer.

On house rules, the cooperative's terms are established: a 3% flip tax applies on sale, and the building permits financing up to 65% of the purchase price. The wood-burning fireplaces are a defining in-unit amenity. These are the concrete facts that shape both underwriting and resale here, and they sit comfortably within the norms of a prime Lenox Hill co-op.

Full closing history with price-per-square-foot over time, the complete retrade record, and every line that has traded.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01391-0045) 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

This is a cooperative, so plan on a full board package, financial disclosure, and an interview. Two terms shape your numbers from the outset: the 3% flip tax at sale and the 65% financing cap, which means you should be prepared to put down at least 35%. Underwrite accordingly.

Beyond the financials, this is a buy-for-the-apartment building: pre-war scale, a wood-burning fireplace, and a quiet mid-block setting matter more than amenity breadth. The location is among the most desirable on the East Side — between Madison and Park, a short walk to Central Park, the Metropolitan Museum and Museum Mile, the Lexington Avenue and Second Avenue subways, and the Madison Avenue retail corridor. For a buyer who wants an intimate, full-service pre-war home in the center of Lenox Hill, this is precisely that.

What to know if you’re selling

Lead with the pre-war substance and the fireplace. Large, well-detailed apartments with working wood-burning fireplaces, in a boutique full-service co-op on a prime Madison-to-Park block, are exactly what the East Side pre-war buyer pursues — and a well-renovated home that preserves its original character commands a premium.

Price against the building's true peer set: the boutique pre-war cooperatives on the Madison-to-Park blocks of Lenox Hill, not the large amenity towers. Be ready to position the 3% flip tax and 65% financing terms candidly; serious buyers expect both and underwrite around them. The board process is standard for a small full-service co-op, and a strong, owner-occupant-minded buyer with the requisite down payment moves through it efficiently.
