A Private Pricing Opinion — what your apartment at Southgate 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.
Southgate is a Bing & Bing building designed by Emery Roth, and for a prewar New York co-op there are few better pedigrees. Bing & Bing were among the city's premier builders of upper-middle-class housing in the 1920s and 1930s, and Roth was the era's defining apartment-house architect. Together they produced 433 East 51st Street in 1930 as one of five sister residences collectively known as Southgate — a coordinated development that brought serious prewar quality to the quiet blocks of Beekman.
Beekman itself is the draw. This pocket of the East 50s, sloping down toward the East River, is one of Manhattan's most tranquil residential enclaves — tree-lined, low-key, and removed from the commercial bustle a few blocks west, yet minutes from Midtown. A Roth-designed, Bing & Bing co-op here delivers exactly what buyers seek in the neighborhood: prewar architecture, real proportions, full-service staffing, and a genuinely peaceful setting.
For buyers, the proposition is a blue-chip prewar co-op with a recognized architectural lineage, a landscaped private garden, and a pet-friendly, pied-à-terre-friendly board — a combination that is increasingly hard to find in Midtown's prewar stock.
Architecture and unit composition
Emery Roth's hand shows in the building's proportion and restraint: a thirteen-story prewar masonry building with the well-handled massing, regular fenestration, and quiet dignity that define Roth's residential work. As part of the five-building Southgate group, 433 East 51st Street shares the development's coordinated design and its handsome landscaped garden, a shared green amenity that is a genuine rarity in the neighborhood.
The building holds 81 cooperative residences, a prewar mix running from one-bedrooms to larger classic layouts, several refined or combined over the building's cooperative life. Prewar construction here means the qualities buyers prize: solid masonry, hardwood floors, real room proportions, and the architectural detail of a Roth building. Individual homes vary in layout and condition, which rewards careful evaluation.
Building operations
Southgate operates as a full-service cooperative: a full-time doorman, a live-in resident manager, a laundry room, a bicycle room, and private storage, organized around the development's landscaped private garden. Electricity is included in the maintenance — a notable feature that simplifies monthly budgeting. On policy, the building is well-suited to a range of buyers: pets are permitted, pied-à-terre ownership is allowed, and a 2% flip tax applies, paid by the buyer. These are settled, buyer-friendly terms that broaden the building's appeal relative to stricter prewar co-ops.
Sublet and pied-à-terre policy
A condominium owner leasing a unit and a co-op shareholder subletting are different rules, and a building-wide rule is different from a restriction on one apartment. This is the building's rule; confirm it for the specific apartment.

Facade safety — Local Law 11
The latest available filing classified the facade as SWARMP — Safe With A Repair and Maintenance Program: the inspector (QEWI) identified conditions requiring monitoring or repair, with repairs due by the deadline stated in the filing. The scope, timeline, and how the building funds the work are building-specific — we review the filings and board materials for you.
How to read this, and where it comes from
QEWI = Qualified Exterior Wall Inspector — a licensed professional engineer or registered architect who meets DOB’s FISP qualifications and signs the report (the independent expert, not the managing agent).
Penalties shown are amounts DOB assessed against filings on record across 2005–10 to 2020–25. The FISP dataset does not record whether they were paid, contested or remain open, so treat the figure as history rather than a current balance and confirm the building’s standing with the managing agent.

Market read. Most recent trades (2026 to date) cleared a median $1,035/sf (floor-adjusted) across 2 sales. 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 3.7% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

What to know if you’re buying
This is a cooperative, so a purchase runs through a board package and interview. The building's terms are buyer-friendly: pets are permitted, pied-à-terre purchases are allowed, electricity is included in maintenance, and a 2% flip tax is paid by the buyer at closing — a cost to factor into your budget from the start. We help buyers understand the building's financing posture and prepare a board package that presents cleanly.
The variables that drive value here are exposure, floor, and condition. A garden- or open-facing upper-floor home is a materially different asset from an interior lower line, and in a 1930 building, thoughtfully renovated homes command the premium. We help buyers read the floor plans, weigh condition against price, and benchmark against the Beekman prewar co-op inventory.
What to know if you’re selling
Lead with the pedigree. The Emery Roth design, the Bing & Bing provenance, and the Southgate development's landscaped garden are durable, recognizable differentiators that distinguish a resale here from generic East 50s stock.
Buyer-friendly terms widen the pool. A pet-friendly, pied-à-terre-friendly board with electricity included in maintenance appeals to a broad set of buyers; these terms belong in the marketing.
Condition and exposure drive pricing. Renovated, well-exposed homes command the premium; a well-presented home should foreground its updates, proportions, and garden or open views.
Check the current competing inventory. Compare available homes and recent closed sales by line, condition and exposure; the unit count alone does not establish scarcity or a seller advantage.

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.
