About the building
442 Third Street is a four-residence condominium conversion by Ascenterra Development. The original building dates to 1920, and the initial condominium closings took place in April 2024. Its renovation created a larger lower duplex and upper floor-through homes within the existing Park Slope building. The condominium was offered under sponsor 442 3rd LLC.
The upper homes include three-bedroom, two-bathroom layouts with living and dining spaces approximately thirty feet long. Private roof decks accompany selected residences. At the base, the garden duplex combines principal rooms above with a lower level having approximately eight-foot ceilings and access to a private yard. Central air conditioning, in-home laundry and smartphone-enabled intercom access are part of the conversion, with space near the entrance for stroller storage.

What to know if you’re buying
The garden duplex has a substantial lower level. Ceiling height and a yard connection don't make every lower room an approved bedroom. The approved layout should govern how that space is represented and used. With four residential owners, decisions about shared systems and the roof also depend on a small voting group, and financing may require additional project review.

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.
