733 Park Avenue is one of the most exclusive addresses on the avenue precisely because of its scale: a 30-story tower that holds only 28 apartments, nearly all of them full-floor. Completed in 1971 on the site of a former Carrere & Hastings mansion that once stood at the corner of 71st Street, it is the tallest residential building on Park Avenue north of 62nd Street, and it was conceived from the outset as a vertical stack of mansion-sized homes for buyers who wanted pre-war proportions with post-war systems.
That is the building's enduring proposition. Where the pre-war co-ops up and down Park divide each floor into one or two apartments behind a shared landing, 733 Park gives almost every owner the entire floor — private elevator-landing entry, light on four exposures, and a footprint that reads as a freestanding residence rather than an apartment. It is a small, tightly held cooperative where a sale is a genuine event, and the board protects that scarcity carefully.
For buyers, the appeal is the rarest thing on Park Avenue: a true full-floor home with white-glove service, in a building intimate enough that the staff knows every household by name. For sellers, the same scarcity is the asset — there is simply very little comparable product on the avenue.
Architecture and unit composition
733 Park departs deliberately from its masonry pre-war neighbors. The tower is clad in a deep brown brick and steps back as it rises, giving the upper floors terraces and the building its distinctive dark, slender profile against the Park Avenue skyline. The recessed, canopied entrance on 71st Street opens to an attended lobby; the design favors discretion over ornament, in keeping with the era and the building's private character.
Inside, the residences are large by any measure — full-floor layouts often described as nine-room homes with multiple bedrooms and baths, gracious entry galleries, and corner living and dining rooms taking light on three or four sides. Ceiling heights, mechanical systems, and central air reflect the building's 1971 construction rather than 1920s infrastructure, which many buyers consider an advantage over the pre-war stock. Upper-floor homes benefit from the setbacks and from open city and park-adjacent views.
Building operations
This is a full-service, white-glove cooperative. Staffing includes a 24-hour doorman and concierge, an elevator attendant, porters, and a resident manager. Amenities are tailored to the small ownership: a fitness center, a wine cellar, and private storage, with the lobby and common areas maintained to a high standard.
The cooperative permits pets and pieds-à-terre with board approval, reflecting the building's posture of accommodating its owners while preserving the residential calm of a 28-home community. As with most prestige Park Avenue cooperatives, the board reviews purchasers closely and expects strong post-closing liquidity; financing is conservative, consistent with the high-end full-floor profile of the building.

Facade safety — Local Law 11
The facade passed its last inspection with no required repairs — nothing to budget for here, and no facade assessment on the horizon for roughly five years.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01405-0072) 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
Buying here means buying a full floor, and the underwriting follows. Expect a thorough board package, a personal interview, and an expectation of substantial liquidity after closing. Financing is permitted but conservative by the standards of trophy Park Avenue cooperatives, and all-cash or low-leverage purchases are common at this level.
The practical questions are about the specific apartment: which floor, which exposures, the condition of the kitchens and baths, and whether the home has been renovated to current standards. With so few units, the building's finances are concentrated among a small group of owners, so reviewing the cooperative's reserves, recent capital projects, and any planned assessments matters more than usual. We help buyers read those records, position a competitive offer, and prepare a board package that clears a discerning board.
What to know if you’re selling
Scarcity is the seller's greatest advantage. With only 28 apartments and infrequent turnover, a well-presented full-floor home at 733 Park has very few direct competitors on the avenue at any moment. The marketing should lead with what the building uniquely offers — full-floor living, light on four sides, white-glove service, and a 1971 building with modern systems in a pre-war neighborhood.
Pricing requires care because comparables are thin; the most relevant evidence is the building's own prior sales and a small set of full-floor Park Avenue cooperatives nearby. Presentation and condition move the number meaningfully at this level, and the board's expectations for the incoming purchaser should shape how a sale is structured and marketed. We advise sellers on timing, staging, and buyer qualification so the transaction reaches the right audience and closes cleanly.
