About the building
478 Third Street is an eight-residence cooperative in a four-story building on a broad Park Slope side street. Its substantial frontage accommodates two apartments on each floor. The interiors include wide living rooms, separate dining rooms and long plans extending through the building. Surviving details include built-in cabinetry, wood floors and fireplace surrounds, with north- and south-facing rooms in the through-floor layouts.
The apartment inventory includes three-bedroom homes of roughly 1,300 to 1,400 square feet. Lower homes can connect with private rear gardens or decks, while selected top-floor residences have private roof decks reached by stairs. Basement storage is assigned to some apartments, and in-home washers and dryers are present in several layouts. The common stair serves all four residential floors.

The retrade record
Lines that have traded more than once in the public record — the building’s appreciation arc, apartment by apartment.
Full closing history with price-per-square-foot over time, the complete retrade record, and every line that has traded.
Sales sourced from NYC Department of Finance recorded transfers (BBL 3-00983-0027) 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; square footage on co-ops is not officially recorded, figures shown are approximate.

What to know if you’re buying
The top-floor outdoor space adds another flight. A roof-deck home involves both the common stair to the apartment and the additional route to the roof. Garden apartments have a different relationship to outdoor space, often opening from the main living level toward the rear. Access, together with the apartment's actual outdoor-use agreement, is a practical distinction within this small cooperative.

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.
