310 Windsor Place

The masonry building follows the meeting of the streets at the park edge. Its corner configurations are particularly distinctive: one three-bedroom home has a large dining room opening to a living room with curved walls and park-facing windows. Other apartments distribute their rooms along more conventional rectangular plans.

The larger recorded apartments run from approximately 1,000 to more than 1,300 square feet. Two-bedroom and three-bedroom homes can overlap in area because a separate dining room or an additional enclosed room changes the count without necessarily increasing the footprint. A third bedroom may be appreciably smaller than the two principal bedrooms.

Some homes retain wood floors, ceiling moldings and windowed bathrooms with clawfoot tubs. Kitchens range from separate windowed rooms to open layouts connected to the living and dining space. Renovated homes have incorporated in-unit laundry, including installations within the kitchen. These features vary across the cooperative.

The apartment sold in July 2025 had multiple exposures and twelve windows, with dedicated basement storage. An earlier three-bedroom sale combined the living, dining and kitchen areas. The plans differ in the placement and enclosure of their rooms.

Upper-floor access is by stairs. Park-facing windows offer a different outlook from courtyard-facing rooms, and the several street exposures mean the direction of a room matters as much as its floor. A lower apartment can still have substantial area; the inventory includes a recorded two-bedroom of about 1,300 square feet.

A live-in superintendent supports day-to-day operations. The common garden, bicycle storage and individual storage spaces are recurring features of the building. Storage allocations differ by apartment; one recent sale included a particularly large basement area. An existing allocation should be identified with the apartment being purchased.

The building appears on DOB's 2026 Local Law 97 covered-buildings list, with approximately 31,200 gross square feet. Its four-story height does not put it outside that program. Energy reporting and any work needed to meet the applicable building-emissions requirements belong in the cooperative's operating and capital planning.

There is no building-level tax abatement. The cooperative's Class 2 property tax is a shared corporate expense reflected through maintenance. The building is already larger than the residential floor area shown under the present zoning comparison; that doesn't point to capacity for further enlargement.

Pets: Cats and dogs are permitted — confirm with the managing agent.

In-unit laundry: Existing installations and hookups occur in the building; approval for a new installation — confirm with the managing agent.

Market read. Most recent trades (2025) cleared a median $905/sf (recorded) across 1 sale. Median listing discount 0.8% 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 3-05257-0035). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. 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.

Sponsor versus shareholder sale: The sponsor offering in 2026 was presented without a board-approval requirement — confirm with the managing agent. That treatment applies to the sponsor transaction; it should not be assumed for a purchase from an individual shareholder. The seller's status therefore affects the application route even within the same building.
