432 Park Avenue

The tower's sponsor inventory falls into three tiers, and the tier shapes what a buyer is acquiring. The tier counts below come from different versions of the offering plan and its amendments and do not sum to the 147-unit original inventory; use a single dated unit schedule before relying on any count. The Department of Finance's current condominium unit-lot schedule (tax year 2027) lists 23 studio lots on floors 28–29, one 8,006-square-foot lot on floor 34 and 102 lots on floors 35–96:

• Floors 28–29 (Studio tier — 27 units, 342–615 sf). Single-bath studios on the building's lower mechanical/transition floors, sold by Sponsor. The sponsor describes these studio suites as available for purchase exclusively to residents of 432 Park, for use as staff quarters (housekeeper, personal assistant, au pair) or for homeowner uses such as guest stays and personal training. They are accessory space for an existing residence, not a standalone entry point to the building; confirm the current ownership and use restrictions in the offering plan amendments for the particular suite.
• Floor 34 (Reconfigurable — 14 small units or one 8,006 sf full-floor). Originally laid out as 14 small studio-sized residences, the sponsor later offered (per a 2018 amendment) the option to combine them into a single 8,006 sf "white box" full-floor unit. The unit could be delivered effectively unbuilt, with the buyer responsible for demising walls, finishes, fixtures, and appliances — an unusual posture for new-construction Manhattan trophy condo inventory.
• Floors 35–96 (Brand-defining luxury tier — 122 units). Standard luxury layouts ranging from 1,422 sf 1BRs at the mid-tower to 8,255 sf 6BR full-floor penthouses at the top. Sponsor pricing climbed steadily with altitude, from the lower-mid tower 1BRs to the 96th-floor 8,255 sf penthouse (originally offered as Apartment 96 FF, 6BR / 7BA / 2 powder rooms / library).

In addition to residential inventory, the sponsor offered 58 storage closets ($7.95M total), 17 wine cellars ($5.9M total), 12 office units on floors 18–20 ($35.6M total), and dedicated Retail Unit, Club Unit (the 26,529 sf amenity floor), and Garage Unit commercial sections. Total sponsor offering at completion: 593,351 sf at an aggregate of $3.127 billion — among the largest single-building condominium offerings in U.S. history.

The 10-foot by 10-foot square windows are the building's interior signature. Each window frames a deliberately monumentalized view; the structural grid produces an interior reading that some buyers respond to as architecturally substantial and others find restrictive (the windows do not open, and the structural grid limits placement of interior walls relative to facade alignment). Ceilings are 12.5 feet in primary rooms.

View altitude is exceptional — apartments above the 50th floor command unobstructed sight lines across Central Park (looking northwest), the East River and Queens (looking east), the Empire State and downtown (looking south), and Hudson and New Jersey (looking west). Lower-floor units have more constrained views, with surrounding development visible at closer distances.

Interior finishes are top-tier — limestone, oak, custom millwork — at the price points the building serves. The kitchens and bathrooms are scaled and detailed for high-end use.

432 Park operates as a typical luxury condominium with full-time doorman, concierge, valet parking, on-site superintendent, and the broad amenity package noted above. The amenity package is concentrated on the building's 12th-floor "Club Unit" — a 26,529 sf dedicated amenity floor that houses the fitness center, pool, spa, residents' lounge, private dining room, conference room, library, screening room, billiards room, children's playroom, and an outdoor terrace. The plan first accepted for filing on July 17, 2012; the first closing occurred on December 22, 2015.

The initial Residential Board of Managers included four sponsor-affiliated directors and an outside member — a meaningful editorial detail linking the building to the city's brokerage establishment from day one. As of mid-2018, the sponsor was still carrying approximately $276,792/month in aggregate common charges and real estate taxes on its remaining unsold inventory — roughly $3.3M/year — a fact that shaped the building's pricing posture through the 2018–2019 sell-down period.

Per the 2017 Schedule A, base carrying costs (common charges + real estate taxes only, before utilities, insurance, or assessments) ran approximately $46/sf per year across the building's unit classes. A 4,000 sf mid-tower 3BR therefore carried roughly $187,000/year in base costs alone; an 8,055 sf full-floor penthouse, approximately $375,000/year. The Tax Cuts and Jobs Act of 2017 was disclosed as a Special Risk in 2018, with the sponsor noting that prior tax projections in the offering plan would no longer be accurate. A permanent Certificate of Occupancy had not been issued as of mid-2018, with the building operating on a temporary C of O.

Common charges and property taxes are substantial. A 3,500 sf 3BR carries common charges in the range of $7,000–$10,000/month plus property taxes that can run $4,000–$10,000/month depending on apartment specifics. Total monthly carry on substantial apartments can exceed $20,000.

The building's mechanical systems have been subject to documented issues across more than a decade of resident occupancy — elevator outages, water intrusion, plumbing failures, audible sway-noise in high winds, and the alleged facade-crack concealment that is now the subject of active litigation. None of this disqualifies the building as a transaction, but it does materially shape the diligence and pricing posture a sophisticated buyer should bring.

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 (2026 to date) cleared a median $4,063/sf (floor-adjusted) across 1 sale. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 13.6% 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 1-01292-7502; 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 Cracks in a $90M Penthouse — The Roebling Report deep dive on 432 Park's defect litigation, with comparable supertall and conversion lawsuits (Hero LIC, 161 Maiden Lane "Leaning Tower," Gramercy Square, 160 Imlay) and a buyer due diligence framework.

Understand which tier you're actually buying. The 432 Park offering plan organizes the building into three structurally distinct tiers — studio suites on floors 28–29, the reconfigurable floor 34, and the brand-defining luxury tier from floor 35 upward. The sponsor sells the studio suites only to existing residents as accessory space, so a buyer there is adding a 500-something-square-foot staff or guest suite in a mechanical/transition floor configuration to a residence above, not buying a standalone home; a buyer in the mid-tower is acquiring a substantial 3–4 BR with the architectural and view characteristics the building is known for. The 2017 Schedule A projected roughly $46 per square foot annually for common charges and taxes across unit classes; that historic estimate is not a current quote or proof that today's costs are comparable. Obtain the specific unit's current charges, tax bill and assessments. Match the floor and configuration to the intended use.

Diligence is the entire game here. This is the most consequential buying consideration at 432 Park and the central thesis of The Cracks in a $90M Penthouse: construction risk is not limited to lower-end or rushed projects. A multi-pronged diligence process is appropriate at any new-construction or recently-converted Manhattan trophy address, and especially here. Specifically:

• Review the offering plan and building history. Understand how the building was put together — who developed, designed, and constructed it; the construction sequencing; any amendments and special-risks disclosures. The original 432 Park offering plan is part of the public record and should be reviewed alongside subsequent amendments.
• Hire an experienced home inspector. Even in new construction — especially in new construction — an inspector can flag workmanship issues, deferred maintenance, or sponsor-era shortcuts that material disclosures may have missed.
• Research developer reputation. Macklowe Properties' and CIM Group's records — including the ongoing 432 Park litigation — are part of the relevant background. Past lawsuits, missed deadlines, and quality complaints are all material.
• Read recent board minutes and reserve studies. Anticipated capital assessments, current litigation funding posture, and major mechanical-system planning all surface here.

The square windows are an architectural commitment. Some buyers respond strongly; others find the configuration restrictive. View the apartment in person at multiple times of day. The windows do not open.

Condo flexibility is real. Foreign buyers welcome; pied-à-terre and investment use permitted under the declaration; subletting allowed.

Mansion tax cliff effects are major. The schedule steps up at multiple thresholds ($5M, $10M, $15M, $20M, $25M). Run pricing through the Mansion Tax Calculator.

Carrying cost is material. Model the full monthly carry (common charges + property taxes + utilities + insurance) carefully — at 432 Park the total monthly nut on a substantial apartment can exceed $20,000 before utilities.

Marketing requires global reach. The buyer pool is international; access to Asian, Middle Eastern, European broker networks is material to selling at the building's price points.

Building issues are part of the buyer's diligence. Sellers should be prepared with current information on engineering reports, capital assessments, and any active litigation. Transparency tends to support pricing; opacity tends to compress it.

Pricing requires building-specific context. Comparable sales at 432 Park are meaningful but heterogeneous — view altitude, floor count, and apartment configuration drive substantial pricing variation.
