310 East 49th Street (Midtown East)

The building is a 13-story red-brick post-war apartment house with a canopied entrance, mid-block on East 49th Street, with the clean mid-century massing of its era. Public records attribute the design to Hyman Isaac Feldman, a prolific architect of New York apartment houses in the mid-century decades — a point worth confirming at diligence. It does not carry landmark ornament; its appeal is the post-war fundamentals — light, a well-kept envelope, and the practical virtues of a good 1959 building.

The residences are predominantly studios and one-bedrooms, with some two-bedrooms among the mix; most homes carry the real closets and sensible proportions typical of the vintage. As with any apartment house, floor and exposure drive the experience: higher floors and the better-exposed lines take more light, while lower and rear units trade at a discount. The rooftop terrace, well-reviewed by residents, and the garden and landscaped outdoor space are genuine amenities that lift the whole building.

310 East 49th Street runs as a full-service, high-touch cooperative — a full-time and part-time doorman under a canopied entrance, a live-in resident superintendent, a rooftop terrace, a garden with landscaped outdoor space, central laundry, resident storage, and a bike room. Pets are welcome. It does not have an in-building gym or on-site parking; the amenity set is the practical, well-staffed package of a good post-war house, and the full-time staffing is a core part of why the building holds its standing. As a cooperative, purchases are subject to board review and the building's financing and residency policies; the building permits up to 75% financing — a minimum of 25% down — and subletting is permitted with board approval after a holding period.

Market read. Most recent trades (2026) cleared a median $665/sf across 2 sales. 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 1-01341-0044) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage on co-ops is not officially recorded, figures shown are approximate.

This is a cooperative, so plan for a board process. A purchase runs through a board package and interview, and the building maintains financing and residency policies typical of a full-service Turtle Bay co-op — a minimum 25% down payment, and subletting permitted with board approval after a holding period. Plan for a primary-residence purchase and a standard board review; the building is genuinely pet friendly.

The unit mix is studios, one-bedrooms, and some two-bedrooms. This is largely a small-unit building, which makes it a natural entry point into a full-service East Side co-op near the U.N.; buyers seeking larger family layouts should benchmark carefully and confirm configurations during diligence.

Floor, light, and exposure are the on-site distinctions. The higher and better-exposed lines are the homes that hold value best, and the roof deck lifts the whole building. Benchmark against Turtle Bay and Midtown East full-service cooperatives.

The location is quiet, cosmopolitan Turtle Bay. A short walk from the United Nations, Beekman Place, and Amster Yard, with the E/M/6 at Lexington–53rd Street and the 4/5/7 at Grand Central a short walk away. Leafy, residential, and international in character.

Lead with the full-service operation and the enclave. A well-staffed post-war co-op with a live-in super, a well-reviewed roof deck, a garden, and a quiet Turtle Bay address near the U.N. and Beekman Place is an easy story to tell; the building's steadiness does real work in a sale.

Benchmark within the building and against Turtle Bay co-ops. With ample in-building turnover, recent comparable sales here are the first reference point; floor, light, exposure, and renovation status determine where a unit lands, on a price-per-room basis.

Foreground the pet-friendly, well-run operation. A pet-friendly, full-service co-op with a roof deck and garden appeals broadly — position those amenities early.

Prepare the board package early. A clean, complete package and a well-qualified, primary-residence buyer move a co-op sale through the board efficiently — we manage that process end to end.
