Almost every apartment on this block of East 62nd Street sits inside a purpose-built building. Curzon House does not. It is two Gilded Age private houses that were stitched together in 1931, run as a private club for half a century, and then cut into twelve large apartments in 1985. The result is a condominium with the room proportions, ceiling heights and stair geometry of a mansion rather than of an apartment house, and with the operating economics of a twelve-unit building rather than a hundred-unit one.
The two halves have separate biographies. No. 4 went up in 1879–80 as a brownstone built and designed by Breen & Nason, who sold it in 1881 to a Knickerbocker-family engineer and railroad-equipment manufacturer. In 1897 the banker William Augustus Read bought it and had Clinton & Russell strip the stoop and the brownstone front and replace them with a limestone neo-Italian Renaissance façade — the elevation that survives, and the one LPC's records single out as significant. No. 6 took the more expensive route. Its 1880 brownstone was demolished outright, and in 1901 the developers William Hall's Sons commissioned Welch, Smith & Provot to build a bow-fronted, five-story Beaux-Arts limestone house on the site, which sold in 1903 to a cotton broker whose fortune collapsed within months of his moving in.
The institutional chapter is what made the current building possible. In 1931 the York Club acquired No. 6, joined it internally to No. 4 through the architect John Hamlin, and reopened in 1932 as what the Department of Buildings recorded as a residence club with sleeping accommodations — while noting that the two remained "separate buildings under the same ownership." The club ran from the combined houses for decades. That is the key structural fact for a buyer: this building's conversion was from institutional club use directly to condominium apartments. It was never a rental building, and there is no rent-regulated tenancy history behind it.
The condominium itself dates to 1985. ACRIS shows the sponsor conveying individual unit lots beginning in October 1985, and the plan carries condominium number 244. Twelve to thirteen homes across six stories and roughly 79 feet of frontage produces apartments at a scale the surrounding prewar cooperatives generally cannot match, with several configured as duplexes and three designated as penthouses.
What has not changed since is the ownership culture. A material share of the unit lots has been held in corporate or trust name for twenty or thirty years, and the building's turnover is thin — several lots have not traded since the 1990s. Curzon House functions less like a conventional condominium and more like a small, closely held building whose apartments come to market rarely.
Architecture and unit composition
From the sidewalk the building reads as two houses, because it is. The No. 4 elevation is the 1898 Clinton & Russell limestone front: arched pediments over the fourth-floor openings, carved lions' heads between the top-floor windows, and French doors onto an iron-railed balcony at the second floor. Next door, the 1901 Welch, Smith & Provot front bows outward, with a rusticated base, a centered entrance rather than a stoop, and a full-width balcony at the third floor. Neither elevation has been meaningfully altered; the Landmarks Preservation Commission's file notes only the 1931 combination.
Inside, the 1985 conversion produced large apartments rather than efficient ones. ACRIS unit designations run 1 through 10 with three penthouses above, and Department of Buildings alteration filings across the 2000s and 2010s repeatedly describe duplex apartments, convenience stairs between levels, and mezzanines — the vocabulary of a house converted, not a floor plate subdivided. Two DOB jobs, one in 2000 and one in 2012, involved combining or renovating across levels; the 2000 filing merged apartments 2 and 3 on the first floor, which is the combination still reflected in the unit lot schedule.
The most recent exterior and rooftop work is documented in LPC's permit file: a 2019 Certificate of No Effect for repointing and replacement of deteriorated painted wood and sheet metal, and a 2022 Certificate of No Effect covering interior alterations together with non-occupiable space and an occupiable rooftop addition, amended that December. A 2014 DOB filing covered structural work for a roof deck. Anyone contemplating an alteration here should assume LPC review is part of the schedule.
Building operations
This is a twelve-residence building in two nineteenth-century structures. There is an elevator and there is staff, but there is no amenity program of the kind found in new construction, and there should not be an expectation of one. The relevant operating questions are the ones specific to old masonry: façade cycle status under Local Law 11, the condition of the roof and the rear elevations, elevator modernization history, and how the board funds capital work in a building where a single project is divided twelve ways rather than a hundred.
Because no offering plan for Curzon House was located in either document library, the building's governing documents, budget and reserve position should be obtained directly from the managing agent before contract. In a building this small, the reserve balance and the assessment history are more informative than any published figure.
Policy framework
Ownership form: Condominium. Sales close through a right of first refusal rather than a cooperative board approval, which produces shorter and more predictable closing timelines.
Pied-à-terre, LLC, trust and foreign ownership: Permitted under the standard condominium framework. The recorded ownership history confirms that entity and trust purchases have been routine here for decades.
Subletting: Permitted under the standard condominium framework, subject to the board's right of first refusal on a lease. Minimum lease terms are not documented in public records.
Pets, financing ceilings, and flip tax: Not firmly documented in public records, and no offering plan was located. Confirm all three with the managing agent at offer stage rather than assuming market-standard terms.
Real estate taxes: No abatement, no exemption, no J-51. Underwrite full unabated taxes on the specific unit lot from the current bill. Note also that the standard co-op/condo property tax abatement does not appear on any unit lot here — a buyer intending the apartment as a primary residence may be able to apply for it, which is worth raising with counsel.
Landmark: Exterior work, and interior work requiring a DOB permit, goes through the Landmarks Preservation Commission. Budget the review time.

Curzon House trades rarely and in large sizes. Recorded arm's-length transfers since 2006 have covered the penthouses and a handful of the lower-floor duplexes, with the combined 2/3 residence trading twice in the last decade. Roughly half the unit lots have not changed hands in more than twenty years, and several remain in the corporate names they were placed into in the 1990s.
That thin float has two consequences for pricing. First, same-building comparables are close to useless in isolation — two sales five years apart in different lines say very little about a third. Second, the building competes against a specific and small pool: large, low-density Upper East Side condominium apartments inside historic-district buildings between Fifth and Park in the low 60s. Prewar cooperative comparables on the same blocks are the wrong reference, because the policy stack, the financing rules and the buyer pool are all different. Index any market read to the last complete year rather than to a partial one. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

What to know if you’re buying
Ignore the PLUTO year built. It says 1910. The building is an 1879–80 house refaced in 1898 joined to a 1901 house. Automated valuation output keyed to 1910 construction is starting from a false premise.
Reconcile the unit count yourself. Twelve homes, thirteen unit lots, and DOB filings that carry both 12 and 17. If you are buying the combined 2/3 residence, confirm that both lots convey.
Underwrite full taxes. There is no 421-a, no J-51 and no other exemption, and the standard condo abatement is not running on these lots.
Confirm the square footage. PLUTO and the Department of Finance disagree by nearly 9,000 square feet at the building level. Measure the apartment.
Assume Landmarks review. Anything you want to change on the exterior, at the roof, or that requires a DOB permit inside, will go through LPC first.
Ask about the underlying structures. Two nineteenth-century masonry buildings sharing a party wall and a common roofline present maintenance questions a single-structure building does not. Get the façade and roof history.

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.
