Change in the building’s median $/sf over each window, on a floor-adjusted basis — standardized to the building’s average floor, so it reflects price rather than which floors happened to sell. This is a different method from The Roebling Index, which publishes plain medians and applies no floor adjustment; the two are not interchangeable. Floor adjustment standardizes for floor only. It does not control for condition, size, exposure, renovation or the mix of what happened to trade. (2022 marks the rate-shock inflection.) Like-for-like repeat-sale figures to follow.
The building has eighteen apartments, with closings beginning in May 2022. Establish actual resale volume from dated transfers; unit count alone does not predict annual turnover or permanent scarcity of comparable sales. Compare post-2020 Gowanus and Boerum Hill condominium sales by total price, reliable measured area, layout and current carrying costs. Verify each apartment’s actual tax bill and benefit schedule rather than assigning Affordable New York benefits to competing inventory by location or age.
Four variables carry the spread inside the stack. Floor band matters, and the fifth floor is a distinct tier: three units instead of five, on the setback level, with the terraces the setback creates. Courtyard versus street exposure matters, because the building's whole design proposition is the courtyard side. Outdoor space matters and is unevenly distributed. And parking matters as a separate asset — nine fee parking units against eighteen apartments, on their own tax lots, priced and carried separately from the residence.
Two building-level facts belong in every conversation about value here. The permanent certificate of occupancy issued in April 2026, after four years of temporary certificates. And the condominium carries flood insurance as a standing budget line. Neither is disqualifying; both are the kind of fact a buyer would rather hear from the listing side in week one than discover from their lender in week four.
Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

The retrade record
Lines that have changed hands more than once in the public record — the building’s appreciation arc, apartment by apartment.
Every recorded sale
Sort any column; filter by unit or keyword. Prices are the recorded transfer amount at the NYC Department of Finance. Every sale sits in one of three states: counted in the building’s medians and trend; shown but excluded as a non-arms-length or nominal transfer; or shown and ⚑ flagged for review — a possible duplicate filing or an extreme $/sf outlier, held out of the statistics pending manual verification rather than allowed to move them.

Sources, exclusions and how these figures are computed
Sales sourced from NYC Department of Finance recorded transfers (BBL 3-00399-7502; each condominium apartment is its own tax lot). 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 from recorded condo declarations and offering plans. Storage, parking, and commercial units are excluded from all figures. Floor- and line-level $/sf are time-controlled (each sale measured against the building’s going rate at the time of sale) and expressed at today’s pricing, so they isolate the floor or line premium rather than blend two decades of market movement.
