About the building
378 Eighth Street is an 1899 townhouse redeveloped by Minerva as a four-residence condominium. The condominium filing was accepted in October 2025 and became effective in January 2026. The conversion retained a small building with one principal residence at each level, on the Park Slope block between Sixth and Seventh Avenues. The development belongs to a group of Brooklyn townhouse projects completed by the same company, with the four homes sold individually during spring 2026.
The layouts include a garden maisonette with two bedrooms and two-and-a-half bathrooms across roughly 1,800 square feet. Upper homes have two-bedroom configurations of approximately 890 to 960 square feet. The lower home opens to its own outdoor area, while the uppermost accommodation occupies the top of the townhouse. Private storage is assigned to each residence. Access to the upper floors is by a common stair.

What to know if you’re buying
The first owners are establishing a four-home association. Common repairs, insurance and operating decisions depend on a small voting group, and some mortgage lenders subject very small condominium projects to additional review. The recent completion of the initial sales also makes the transition from sponsor administration relevant to ownership.

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.
