A Private Pricing Opinion — what your apartment at M at Beekman 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.
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, there is no co-op board admission; purchases run through the condominium's application and right-of-first-refusal process. Pied-à-terre use is permitted; confirm financing, leasing and ownership-entity rules in the current declaration, bylaws and house rules. 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.
Architecture and residences
The building's exterior preserves the prewar brownstone fabric of the Beekman block; the interiors are contemporary and loft-scaled. The 23 residences run from one- and two-bedroom lofts to two duplex penthouses and four triplex townhouse-style homes — a layout mix that delivers volume, multiple levels, and private outdoor space far beyond what the typical postwar tower line offers. Oversized windows, open living layouts, and modern kitchens and systems are standard.
Because the unit mix is so varied — lofts, duplexes, triplexes — value here is highly layout-specific. Floor level, the number of levels in a given residence, outdoor space, exposure, and finish state are all decisive, and each home is best read on its own merits against the others in the building and the surrounding boutique-condominium stock.
Amenities and lifestyle
For a building of 23 units, the service model is full: a 24-hour doorman and concierge, an elevator, a fitness room, and a garden. The boutique scale means a quiet, low-density living experience — a deliberate contrast to the large towers nearby.
The location supplies the rest. The building sits on East 50th Street between First and Second Avenues, on one of the Beekman / Turtle Bay area's calmest residential blocks, a short walk from the United Nations, Sutton Place, the East River esplanade, and Midtown's transit and dining.

The latest available FISP filing classified the facade as Safe — no repairs were required at that inspection. A filed Safe grade is not a guarantee of current condition: owners still maintain the facade and, where required, observe parapets each year. Future inspection timing (Local Law 49 of 2025 changed the cycle framework from October 1, 2026), repair and any assessment decisions remain building-specific.

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.

Market read. Most recent trades (2026 to date) cleared a median $780/sf (floor-adjusted) across 1 sale. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 5.4% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

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.
The condominium process applies. There is no co-op board admission; purchases run through the condominium's application and right-of-first-refusal process. Pied-à-terre use is permitted and the building is pet-friendly; confirm financing, trust, LLC and investor-use rules against the offering plan and current house rules.
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.

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.
