BUILDING RECORD · BIN 3016580

Windsor Terrace-South Slope, Brooklyn
A consolidated public-record view · updated Jul 17, 2026
A building-level summary of matched filings, active-status records and published identifiers.
The lot
The lot holds a 3-story walk-up apartment building built in 2024, with 5 homes, on a 4,017 sq ft lot.
The apartments
8 condominium apartments are assessed on this block, and the typical one is 697 sq ft (65 m²). They run from 60 to 88 m².
The city values the typical one at $375,814. That is the Department of Finance’s market valuation for tax, not an asking price and not a sale.
What it sold for
3 apartments on this tax block changed hands in the year the city last published, at a median of $469,898, from 419,715 to 820,000.
Recorded sale prices from the Department of Finance’s rolling file, covering the year to Aug 31, 2026. Transfers under $10,000 are left out: New York records deed transfers between relatives at a dollar, and those are not sales. No apartment number and no name is carried from either side.
Owner of record

As the assessment roll records it. Only owners that read as a company are shown here; where the roll names an individual, nothing is published.

What is recorded here
New York City's Building Identification Number helps connect filings that may use different application numbers or describe different scopes of work. The records below are grouped because they publish BIN 3016580. They should not be read as a single construction project unless the underlying filings say so.
The matched set includes 14 alteration filing. Its latest status categories are 14 approved. Each filing page preserves its own status, dates, scope and source identifier.
Highest recorded values may come from different filings and must not be combined into one proposed project. Open the individual filings below for their exact scope. Values outside the publication's conservative data-quality bounds are withheld pending source review.
