About the building
445 First Street is a four-residence brownstone cooperative between Sixth and Seventh avenues. Its apartment inventory includes two-bedroom floor-through homes, with living areas facing the street and bedrooms toward the interior of the block. Architectural reporting identifies Albert E. White as the architect and owner who filed plans for the flats building in 1890. The small building has stair access to its upper homes.
High ceilings, hardwood floors and large south-facing windows are features of the residential plans. The uppermost home has skylights and an interior spiral stair to a small upper space. That upper level connects to exclusive roof rights, although the roof itself is undeveloped. The residential inventory also includes conventional single-floor layouts below, with interiors of roughly 960–1,150 square feet among homes that have traded.

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 3-00966-0050) 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
Roof rights aren't an approved terrace: The upper home's exclusive rights concern an undeveloped roof. Creating usable outdoor space would require board approval and any applicable construction approvals, along with a clear agreement about roof protection, access and future repair costs. The cooperative's four shareholders would be involved in decisions affecting the common building structure.

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.
