1125 Park Avenue

The entrance is canopied with a two-and-a-half-story entrance surround capped by a broken pediment. Bandcourses run above the first, third, and 14th floors; limestone quoins line the building edges; the top two floors carry two-story window surrounds — a Schwartz & Gross signature meant to distinguish the building's crown.

The Schwartz & Gross body of Park Avenue work — the most prolific of the 1920s — includes 470, 525, 885, 888, 910, 911 (The Alvarado), 930, 941, 970, 983, 1045, 1070, 1085, 1111, 1165 (The Livingston), and 1185 Park Avenue. The Bricken Construction Company commissioned much of the firm's northern Carnegie Hill work; 1125 Park is the Tishman exception.

The 72 apartments distribute across the building's 15 stories at two apartments per landing per elevator (semi-private landings). Apartment configurations typically run six to nine rooms with most units featuring wood-burning fireplaces. Building square-footage data per NYC Department of Finance records: residential 110,629 square feet plus approximately 2,000 square feet of commercial.

1125 Park operates as a full-service Carnegie Hill cooperative under the corporate entity 1125 Park Avenue Corp. The operational baseline includes:

• 24-hour doorman and concierge with controlled-access elevator panel from the concierge desk — a structural security feature uncommon among peer pre-war Park Avenue cooperatives
• Live-in resident manager
• Half-court basketball court — created from a 4,000-square-foot former basement coal-storage bin with 27-foot ceilings (the conversion was documented by Constance Rosenblum in the July 15, 2011 New York Times article "Hidden Gems in the Basement")
• State-of-the-art fitness center
• Children's playroom with library
• Bike room
• Private storage bins allocated per apartment
• 84-bottle wine cellar allocated per apartment
• Freight elevator (also controlled from the concierge desk)

The building does not carry an on-site garage, roof deck, or sidewalk landscaping.

Verified against the building's house rules, governing documents, and public records:

• Financing maximum: 50 percent
• Minimum down payment: 50 percent
• Flip tax: 2 percent of gross sale price, buyer-paid at closing
• Tax deductibility on maintenance: 40 percent (Compass building data)
• Pets: Permitted
• In-unit washer/dryer: Permitted
• Subletting: Board approval required; subletter interview standard; typical Carnegie Hill duration limits
• Trust ownership: Subject to board approval with beneficial-owner disclosure and primary-occupancy commitment
• LLC ownership: Subject to board approval with full beneficial-owner disclosure
• Pied-à-terre: Not affirmatively published; board preference is primary residence
• Post-closing liquidity: Typical Carnegie Hill threshold (2x to 3x annual carrying costs); confirm specific board threshold at application stage
• Board interview: Required; full financial and personal-reference disclosure

The 2 percent buyer-paid flip tax structure is meaningful at closing — on a $5 million purchase, $100,000 of additional buyer cost on top of mansion tax and standard closing costs.

Recent sales

Recent transfers 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. $/sf is measured on the latest sales with reliable square footage (2010): a median $1,148/sf (recorded) across 1 sale. The building has traded as recently as 2026. Median listing discount 3.2% 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 1-01519-0001). 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.

Per trade-press "Most Notable Resi Sales of the Week" coverage of March 4, 2019, Alfonso and Lindsay Kimche sold their unit in March 2019 (having acquired it in 2014); the buyers were Douglas and Patricia Sacks. The Roebling Report has not identified a verified A-list celebrity sale at 1125 Park — a residency pattern consistent with Tishman-developed buildings, which historically attract financial- and professional-class residents rather than entertainment-industry buyers.

The non-landmarked status is structurally consequential. Outside the Park Avenue Historic District; exterior modifications are not subject to LPC review; the building's capital project flexibility is materially greater than peer contributing-structure inventory.

The amenity inventory is among the most developed in the pre-war Carnegie Hill tier. The half basketball court, the coal-storage-converted fitness center, the children's playroom with library, the in-unit wine cellars together produce one of the most architecturally articulated amenity programs on the corridor.

The controlled-elevator-access security protocol is structural. Materially more robust than typical Park Avenue cooperative security baselines.

The Tishman developer pedigree connects to a substantial broader portfolio. Julius Tishman & Sons → Tishman Construction → Tishman Speyer institutional continuity is real.

The 2 percent buyer-paid flip tax is meaningful at closing. Factor into all carrying-cost and net-proceeds calculations.

Verify operational specifics during due diligence. Specific board approval framework, sublet duration limits, post-closing liquidity threshold, current capital project pipeline, and the LL11 façade cycle on the 1926 vintage should be reviewed against current management documents.

Closing timelines are cooperative-standard. Plan for 6–10 weeks from contract through board approval to closing.

Marketing should emphasize the non-landmarked status as a real structural advantage. The exclusion from LP-2547 produces capital project flexibility uncommon among peer Park Avenue Historic District inventory.

The amenity inventory supports premium positioning. The half basketball court, the coal-storage-converted fitness center, and the in-unit wine cellars are real assets uncommon in peer Carnegie Hill cooperative inventory.

The Schwartz & Gross + Tishman architect-developer credential is real institutional context.

Pricing should reference recent comparable closings. Same-line comparables, adjusted for floor and condition, should anchor positioning.

Closing timelines are cooperative-standard.
