33 East 74th Street (Whitney Condos)

The Madison Avenue frontage preserves the facades of the 1876–77 brownstone row — stoops long removed when the avenue was widened, bases converted to retail generations ago — while the 74th Street elevation pairs the recessed residential entrance with the Atterbury mansion: 33 feet wide, red brick with quoins, tall arched second-floor windows, and a proper cornice, built for Julian Wainwright Robbins and his wife Sarah, a Vanderbilt niece. Behind all of it, the 2014 conversion is new construction — new structure, new mechanicals — with three setback levels added above the Madison cornice line for the penthouses.

The 10 residences are large by any Manhattan standard. The simplexes run to roughly 3,900 square feet with 23-foot entry galleries; the three penthouses range from about 4,800 to 6,300 square feet with private terraces of 2,300 to 2,900 square feet; and the Atterbury Townhouse is a 10,088-square-foot, five-bedroom quadruplex with its own terrace — effectively a mansion with condominium paperwork. Finishes from the conversion are consistent across lines: 10-foot ceilings, travertine galleries, ebony double doors, oversized multi-paned windows behind the historic facades. Because the envelope is protected, light and outlook are townhouse-scale — gracious, leafy, mid-block — rather than tower views; buyers should weigh that honestly against the square footage.

This is a boutique full-service condominium: concierge service, a fitness center, a roof deck, and private storage, run for 10 residences above a separately held retail base. The amenity program is deliberately compact — the building sells privacy and scale, not an amenity floor. The Madison Avenue retail below is a structural fact of ownership: it underwrites the corridor's energy and is part of the address's value, but buyers should understand the commercial condominium structure and current tenancy during diligence. Policy specifics are thinly documented publicly; we verify the framework with the managing agent during diligence.

Recent sales

Recent closings at this building, from The Roebling Research Library. Prices are the transfer amounts recorded with the NYC Department of Finance; apartment-level detail is checked against the building’s own file in The Roebling Research Library before publishing.

Market read. Most recent trades (2018) cleared a median $3,895/sf (recorded) across 1 sale. Median listing discount 4.3% 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 1-01389-7503; 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 condo structure is the scarcity. Large-format residences with condominium transfer mechanics — LLC and trust structures, no shareholder board interview — are rare in the heart of the Madison/Park co-op belt. For global buyers and family-office structures, this materially widens what is possible at this micro-location. Confirm specific structures with the managing agent and your attorney.

You are buying inside a protected envelope. The Upper East Side Historic District and the Madison Avenue preservation zoning govern the exterior. LPC reviews covered alterations, including window, façade and roof-terrace work, without guaranteeing that the block remains unchanged. Staff approval may apply and ordinary maintenance may be exempt; interior work requiring a DOB permit also needs LPC review. Confirm the scope and permit route before setting the schedule.

Calibrate the view expectation. These are house-scale residences behind 19th-century facades, not tower apartments. Light is real — penthouse terraces and the setback levels are generous — but buyers cross-shopping glass condos should tour at multiple times of day.

Underwrite the carry. Common charges and taxes on 4,000–10,000-square-foot residences are trophy-tier. Run the True Monthly Carrying Cost Calculator on the specific unit before offering.

Verify the policy stack. Financing conventions, leasing terms, and pet policy are not well documented publicly for this building. We confirm current terms directly with the managing agent during diligence.

Market the provenance with precision. The Whitney assemblage, the Atterbury mansion, the preservation fight that saved the row, Beyer Blinder Belle, and the Sotheby's headquarters next door — this is the best-documented narrative on the block. It should be told with dates and names, not adjectives.

Same-building comps barely exist — corridor comps decide. With 10 units, pricing anchors to the boutique pre-war-envelope condo set (The Bellemont, the Marquand, 135 East 79th) and to what house-scale square footage commands off Madison. We build that comp set unit by unit.

Expect a deliberate, global buyer pool. The audience for condominium residences at this scale is thin, international, and advised. Marketing should be prepared for a long arc, with documentation — offering terms, historic-district mechanics, retail-condo structure — packaged for buyers' counsel from day one.
