About the building
344 8th Street is a four-story brownstone cooperative near Sixth Avenue. Its four apartments occupy the low-rise house, which is self-managed and has shared laundry and storage in the basement. The building retains features associated with its row-house form, including tall windows, ornamental woodwork and fireplaces. Its existing floor area exceeds the residential floor area allowed by the present R6B zoning district. It is outside the Park Slope Historic District.
The homes include floor-through two-bedroom layouts with additional study space, a lower apartment with private garden access and an upper home with skylights. The distinction between an enclosed bedroom and an adjoining office is important in the floor-through plans, where rooms follow the depth of the house. Wood-burning fireplaces survive in some apartments. Laundry is available both through the shared basement facilities and within certain homes. The garden is associated with the lower residence; upper apartments have their own interior configurations and exposures.

The retrade record
Lines that have traded more than once in the public record — the building’s appreciation arc, apartment by apartment.
Sales sourced from NYC Department of Finance recorded transfers (BBL 3-01005-0041) 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
Self-management is part of ownership here. Four shareholders coordinate the building's operating decisions and capital work. The private garden also creates a distinction between common structural responsibilities and outdoor elements serving the lower home; DOB signed off rear-yard fence work in June 2024. The cooperative's allocation of those responsibilities matters when garden or boundary work recurs.

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.
