33 East 70th Street is a low-density pre-war cooperative of exactly the kind that defines the central Upper East Side: a 1928 Schwartz & Gross building of red brick over a limestone base, holding only about 44 apartments across 11 stories, one block from Central Park and steps from the Frick Collection and the Madison Avenue gallery and retail district. It is a sister building to 30 East 71st Street, designed by the same firm, and it sits as a contributing building within the Upper East Side Historic District.

The appeal is the classic white-glove proposition: scarcity, scale, service, and an address at the heart of Lenox Hill. With so few apartments, the building turns over infrequently, and its residences carry the proportion and finish — formal entertaining rooms, generous ceilings, gracious layouts — that buyers of pre-war co-ops seek. The 24-hour doormen and hall attendants and a live-in resident manager support a level of service consistent with the building's stature.

The location near Madison Avenue at 70th Street is among the most desirable on the Upper East Side: a quiet, gallery-lined block one turn from Central Park, the Frick, and the avenue's flagship retail.

Architecture and unit composition

The roughly 44 residences span 11 stories in a building designed for space rather than density. The Schwartz & Gross design is Colonial Revival in spirit — red brick over a limestone base, restrained ornament, and a discreet canopied entrance — the architectural language of the era's premier Upper East Side apartment houses. Interiors carry pre-war proportions: high ceilings, formal layouts, and the entertaining flow that the period's luxury co-ops were built to deliver.

As a contributing building in the Upper East Side Historic District, exterior alterations are subject to Landmarks Preservation Commission review.

Building operations

33 East 70th Street operates as a full-service white-glove cooperative with 24-hour doormen and hall attendants, a live-in resident manager, a renovated lobby, three elevators, a fitness center, bicycle storage, individual storage bins, and a central laundry. The small share count concentrates building costs across few owners, which is typical of buildings of this stature; prospective purchasers should review the co-op's financial statements, reserve fund, and any assessment history, and confirm the current sublet, financing, pied-à-terre, and flip-tax terms in writing during due diligence — pre-war co-op boards of this tier typically maintain conservative financial requirements.

Recent sales

As a cooperative, 33 East 70th Street is benchmarked on a price-per-room basis, with monthly maintenance and the building's white-glove cost structure in context. The defining pricing dynamic is scarcity: with roughly 44 apartments, inventory is thin, turnover is infrequent, and a single closing can reset the comparable set. The combination of a Schwartz & Gross pre-war envelope, a historic-district location one block from Central Park, and full white-glove service supports premium per-room pricing relative to lesser pre-war co-ops. Larger, higher-floor, and well-renovated apartments command the building's top figures. Specific financing, sublet, and any flip-tax terms should be confirmed at offer stage.

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 1-01385-7502) 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 white-glove pre-war co-op. Expect the proportion, service, and board process that the category implies, and a board that will review finances and intended use closely.

Inventory is scarce. With so few apartments, the right opportunity may require patience and decisiveness when it appears.

Benchmark per room. Compare price per room and maintenance against other Lenox Hill pre-war co-ops.

Confirm board policy in writing. Financing limits, sublet, pied-à-terre, and any flip tax are board-set and should be verified at offer stage.

What to know if you’re selling

Scarcity is your leverage. Few apartments and infrequent turnover mean a well-prepared listing draws focused attention. Apartment-level positioning is everything.

Lead with the architecture and the address. A Schwartz & Gross pre-war co-op one block from the Park, in the historic district, is a distinctive story.

Prepare the buyer for the board. Realistic expectations about the board's requirements smooth the path to closing.
