1125 Park Avenue sits at the architectural and operational seam of the Carnegie Hill pre-war Park Avenue tradition. The 1926 Schwartz & Gross commission for Julius Tishman & Sons — the developer whose broader 1920s Park Avenue portfolio includes 888 Park Avenue (1925–26), 941 Park (1927), and 1095 Park (1930), and whose 20th-century successor entities became Tishman Construction, Tishman Realty, and Tishman Speyer (Jerry Speyer with Robert Tishman in 1978, today one of the largest commercial real estate operators in the world with more than $115 billion in assets under management) — sits among the firm's most architecturally consequential mid-1920s Park Avenue commissions.
The single most important structural fact about 1125 Park is that the building is not within a historic district. The owners of 1125 Park (along with the owners of 1036 Park) successfully requested exclusion from the Landmarks Preservation Commission's Park Avenue Historic District designation (LP-2547) during the April 2014 designation process. The Park Avenue Historic District covers Park Avenue from the northeast corner of 79th Street to the south side of 91st Street and contains approximately 64 contributing buildings; 1125 Park sits at the northeast corner of 90th but is the carved-out exception. The exclusion produces a structurally specific operational reality: exterior modifications at 1125 Park are not subject to LPC review, the broader regulatory framework applicable to contributing buildings within the district does not apply, and the building's capital project flexibility is materially greater than peer Park Avenue Historic District inventory.
Beyond the architecture, three things set 1125 Park apart in the Carnegie Hill market. The building carries an unusually substantial amenity inventory — much of it carved from its original coal-storage infrastructure — paired with a controlled-elevator-access security protocol run from the concierge desk. And the Schwartz & Gross + Julius Tishman & Sons architect-developer pedigree ties 1125 Park to a substantial 1920s Park Avenue body of work.
Architecture and unit composition
Architectural records describe 1125 Park as "a handsome, 15-story, 72-unit cooperative apartment house" — the architectural register characteristic of Schwartz & Gross at the firm's mid-1920s peak. 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.
Building operations
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.

What to know if you’re buying
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.
What to know if you’re selling
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. The Unit 8B $4.00 million July 2025 closing and the Unit 3E $4.40 million March 2024 closing provide recent reference points.
Closing timelines are cooperative-standard.
