343 East 50th Street — M at Beekman — is a boutique condominium of 23 residences created in 2007 by combining two adjacent prewar brownstone buildings, at 343 and 345 East 50th Street, behind preserved historic facades. The architect Adam Kushner led the conversion, keeping the street-level brownstone character of the Beekman block while delivering contemporary, loft-like homes behind it. The result is an unusual product for the area: new-construction-quality condominium interiors — including duplex penthouses and triplex townhouse-style homes — inside a low-rise prewar shell on one of Midtown East's quietest residential streets.
With only 23 units in six stories, the building is small, intimate, and full-service, the opposite of the large postwar towers that supply much of the surrounding co-op inventory. It is positioned at buyers who want scale and character in the home — lofts, duplexes, triplexes — with the financing latitude and ownership flexibility a condominium provides.
For buyers, the appeal is the combination: a distinctive, loft-like Beekman home with condominium flexibility, on a residential block a short walk from the United Nations, Sutton Place, and the East River.
Building operations
343 East 50th Street operates as a condominium with 24-hour doorman and concierge service. As a condominium, it offers what the area's co-ops structurally cannot: financing is not subject to co-op-style caps; there is no admissions board, so a purchase clears a condominium's lighter right-of-first-refusal rather than a board package and interview; and pied-à-terre, trust, LLC, and investor purchases are customary, with subletting and resale materially freer than at a cooperative. The building is pet-friendly. The common charges, the minimum down payment, and the precise sublet and pet rules are confirmed against the offering plan and the managing agent during due diligence.
Recent sales
343 East 50th Street prices in the boutique Beekman / Turtle Bay condominium tier, and value is read on a price-per-square-foot basis against comparable boutique-condominium inventory. Because the building's homes range from lofts to duplexes to triplexes, building-wide averages are less informative than apartment-level reads: the multi-level penthouses and townhouse-style homes command the top of the range, while the single-level lofts anchor the entry tier. Outdoor space, the number of levels, floor, exposure, and condition are the decisive variables. Capture the apartment-level specifics and benchmark to the right boutique comparable set; the small unit count means each sale is a meaningful data point.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01343-7504) 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 from recorded condo declarations and offering plans.
What to know if you’re buying
The character-plus-flexibility case is the core. A loft-, duplex-, and triplex-heavy boutique condominium behind preserved prewar brownstone facades offers volume, multiple levels, and private outdoor space with condominium ownership latitude on a quiet Beekman block.
Condominium flexibility is real. No board package or interview — a right-of-first-refusal rather than admissions; financing is not co-op-capped; pied-à-terre, trust, LLC, and investor use are customary, and the building is pet-friendly. Confirm the current rules against the offering plan.
Value is layout-specific. With lofts, duplexes, and triplexes in one small building, price each residence on its number of levels, outdoor space, floor, exposure, and condition rather than on a building average.
Model the full carry. Run common charges plus property taxes plus utilities and insurance carefully; confirm the minimum down payment with the managing agent.
Mansion-tax thresholds can apply. At the larger homes' pricing, run the numbers through the Mansion Tax Calculator.
What to know if you’re selling
Lead with the layout and the character. The loft, duplex, and triplex volumes, the preserved brownstone facades, and the boutique full-service model are durable differentiators against the large towers and plainer condominiums nearby.
Benchmark to boutique Beekman and Turtle Bay condominiums and position each home on its number of levels, outdoor space, floor, exposure, and condition.
Closing mechanics are condominium-standard — a right-of-first-refusal rather than a board process — a faster, more predictable path that itself appeals to the flexibility-minded buyer this building attracts.
