The Heritage trades as late-2000s Park Slope condominium stock, priced per square foot, with one feature that separates it from most of its peers: a full 421-a benefit that runs into the next decade. Resale turnover is thin — a 21-residence building with owners who have held for years — and recent recorded sales are few. Within the building, value turns on outdoor space (the yards on 1D and 1E, the terraced upper lines, the roof terraces), on whether a ground-floor duplex's cellar level is counted honestly, and on parking, which is sold as a separate unit.
Through 2025 the tax benefit was a large part of each apartment's value against fully taxed buildings nearby. That component shrinks year by year once the phase-out starts in 2030/31. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

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 3-00969-7503) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price. 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.
