A Private Pricing Opinion — what your apartment at 700 Park Avenue would likely sell for today, what it costs to sell, and what you’d walk away with — reviewed personally against condition, exposures, renovation quality, and the competition actually on the market.
700 Park Avenue is among the most architecturally consequential post-war cooperatives on Lenox Hill Park Avenue. Completed in 1959 by Kahn & Jacobs with Paul Resnick and Harry F. Green as associated architects, the 19-story building replaced the Knoxville-gray-marble English Renaissance city residence of Commodore Arthur Curtiss James — the railroad magnate who controlled approximately one-seventh of all U.S. rail track at the height of his industrial career and served as commodore of the New York Yacht Club. The James mansion site had earlier housed Union Theological Seminary, placing the corner at the conjunction of multiple consequential 19th-century institutional and residential occupants.
The Kahn & Jacobs design produced an architectural register specific to the late-1950s Park Avenue building cycle. The glazed-gray-brick façade sits on a two-story polished granite base, with continuous glass balcony bands along Park Avenue exposures and substantial setback configurations producing private outdoor space on the upper floors. The architectural composition is consciously calibrated to the corridor's pre-war architectural tradition — particularly the Delano & Aldrich Union Club across Park Avenue, where the architectural dialogue is most legible — while executing in the modernist material vocabulary of the era. The 48-residence intimate scale produces a structurally distinct cooperative operational character. Apartment configurations are unusually substantial for the post-war Park Avenue cooperative tier: entrance galleries measuring 16 to 21 feet, living rooms 27 to 31 feet, dining rooms 22 to 23 feet, and apartment-level features including wood-burning fireplaces, butler's pantries, solariums, and parquet de Versailles flooring across multiple units. Penthouse-tier apartments carry wraparound terraces; combined-unit duplexes reach 3,500 square feet and above. Several apartments retain Ward Bennett-designed mid-century-modern interior installations that constitute their own internal architectural pedigree.
Architecture and unit composition
The 48 cooperative apartments distribute across the building's 19 stories in configurations ranging from substantial two-bedroom apartments through penthouse-tier duplexes. Apartment scale and ceiling heights are calibrated to the late-1950s Park Avenue building cycle, with the layout discipline and architectural finish specifications characteristic of Kahn & Jacobs's broader luxury residential work.
Pricing inside the building follows apartment scale, outdoor space, and condition, and comparables are read apartment by apartment.
Building operations
700 Park operates as a full-service cooperative with 24-hour doorman, concierge, and live-in superintendent. A recently renovated contemporary lobby anchors the building's ground-floor presentation. The amenity infrastructure includes a fitness center, an on-site parking garage, two landscaped terraces including a rooftop installation, and private storage. The cooperative policy framework — 40 to 60 percent maximum financing, 2 percent buyer-paid flip tax, pet and pied-à-terre allowances on a case-by-case basis — is calibrated to the pre-war Park Avenue cooperative tradition that Kahn & Jacobs's architecture deliberately referenced.

What to know if you’re buying
The Kahn & Jacobs architectural pedigree is real.
Apartment scale is substantial. Entrance galleries 16–21 feet, living rooms 27–31 feet, dining rooms 22–23 feet — apartment proportions consistent with the surrounding pre-war Park Avenue cooperative tradition rather than the smaller-scale post-war building norm.
The 48-residence intimate scale produces a specific cooperative culture. Materially smaller than peer post-war Park Avenue inventory; the building culture is correspondingly intimate.
The on-site parking garage is structural infrastructure. Park Avenue parking is constrained; building-owned parking is meaningful.
The historic Commodore James mansion site context is real cultural history. The building's position at the corner anchors a substantial residential-and-institutional 19th-century continuity.
Confirm policy specifics during due diligence. Specific board approval framework, financing percentages, and sublet duration limits should be verified.
Closing timelines are cooperative-standard. Plan for 6–10 weeks from contract through approval to closing.
What to know if you’re selling
Marketing should emphasize the Kahn & Jacobs architectural credential and the apartment scale. Both are structural identity features.
Apartment-level Ward Bennett-designed interior installations are real value features. Buyers attentive to mid-century-modern architectural pedigree should be reached specifically.
Pricing requires apartment-level comparable analysis. The relevant comparable is an apartment of similar scale and outdoor space, adjusted for condition, not a building-wide average.
Closing timelines are cooperative-standard.

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
