230 East 73rd Street — Eastgate — is an Emery Roth-designed, Bing & Bing-built prewar cooperative at the heart of the "Eastgate" enclave of brown-brick apartment houses that Bing & Bing raised along East 73rd Street. It pairs one of Manhattan's most celebrated apartment architects with one of its most respected prewar developers, delivering genuine architectural pedigree at Lenox Hill pricing rather than the Park-and-Fifth premium.
The building's appeal rests first on its Emery Roth / Bing & Bing pedigree. Roth's residential work defines much of prewar Manhattan's finest apartment stock, and Bing & Bing's buildings are prized for construction quality and layout intelligence. Eastgate was originally marketed with its sister buildings as an enclave, its apartments sold as "mansionettes" — a positioning that still reads in the generous, well-proportioned layouts. Its near-twin at 235 East 73rd Street across the block completes the paired-building urban context that gives the enclave its distinctive character.
Layered onto the architecture is a landscaped courtyard and full-service program — a planted rear garden, a fitness center, two elevators, and staffed lobby service that give the building operational depth uncommon among boutique Lenox Hill cooperatives.
Architecture and unit composition
Eastgate is a 12-story prewar cooperative of roughly 92 units, designed by Emery Roth and built by Bing & Bing in 1936. The brown-brick facade carries Georgian/Tudor-influenced masonry with textured "knobby" brickwork and random inset stones, a canopied two-story sandstone entrance surround with a revolving door, a step-down lobby, decorative gargoyles, and a rounded top-floor parapet with a decorative rooftop water-tank enclosure. The lobby carries Art Deco detailing.
Original apartments featured sunken living rooms and generous "mansionette" proportions; fireplaces in this building are decorative rather than working. The mix runs from one-bedrooms through larger combined and penthouse units, some with terraces. The building was converted to cooperative ownership in 1987.
Building operations
Eastgate operates as a full-service prewar cooperative with a full-time doorman/concierge, two elevators, a landscaped courtyard/rear garden, a fitness center, a central laundry room, private storage (waitlisted), and a bike room. There is no parking garage. The superintendent is understood to be full-time; live-in status should be confirmed at offer stage.
Financing is permitted up to 80% (20% minimum down payment). A transfer fee (flip tax) applies; the building's fee has been reported on a per-share basis, and the exact rate and payer should be confirmed against the current offering plan and house rules. Subletting is permitted, with an occupancy period required before subletting and term limits thereafter — the specific terms should be verified against house rules. Pied-à-terre ownership, co-purchasing, and guarantors are permitted. As with any cooperative, board approval and a board interview are required.

Eastgate trades as an architecturally pedigreed prewar Lenox Hill cooperative, with value expressed on a per-room and per-share basis. Pricing reflects the Emery Roth / Bing & Bing provenance and the generous "mansionette" layouts: the building's appeal to buyers seeking prewar bones and full-service infrastructure without the Park-and-Fifth premium supports steady demand across one-bedroom through combined and penthouse inventory. As with any cooperative, per-room value is best read within a unit's specific line, floor, exposure, and condition rather than a single building average; comparable selection should account for terrace configuration and renovation level.

Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk.

What to know if you’re buying
The Emery Roth / Bing & Bing pedigree is real institutional context. One of prewar Manhattan's finest apartment architects paired with a top prewar developer, at Lenox Hill pricing.
The "mansionette" layouts are a genuine differentiator. Sunken living rooms and generous proportions distinguish the interior program from typical postwar stock.
Financing is comparatively flexible for a prewar co-op. Up to 80% financing (20% down) is more permissive than many Park-and-Fifth peers.
Confirm the flip tax and sublet terms. The transfer fee and subletting rules should be verified against current house rules and the offering plan at offer stage.
Board approval and a board interview are required. Build the cooperative timeline into your plan.
What to know if you’re selling
Lead with the architecture. Emery Roth, Bing & Bing, the "mansionette" heritage, and the Eastgate enclave context are the marketing story.
Highlight the amenity depth. Landscaped courtyard, fitness center, two elevators, and full staff differentiate Eastgate from boutique Lenox Hill peers.
Price within the enclave carefully. Take care not to conflate Eastgate with its near-twin at 235 East 73rd — comparables should be building-specific and account for terrace and renovation variation.
Prepare buyers for the board. A clean board package and realistic financial guidance shorten the path to approval.
