About the building
Diamond Haus is a low-rise condominium whose frontage is divided into three sections with separate elevated entrances. Paul Lombardi's design groups the windows vertically between masonry and metal framing. The reinforced-concrete structure had topped out by February 2023; the first apartment closings followed in January 2024.
The building contains two- and three-bedroom homes, with private gardens at the base and roof terraces above. Setbacks over the third story accommodate the upper outdoor spaces beneath projecting canopies. Two-bedroom homes occupy the lower levels, with three-bedroom homes at the top.

Market read. Most recent trades (2026 to date) cleared a median $1,618/sf (floor-adjusted) across 1 sale. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 1.7% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.
The retrade record

Sales sourced from NYC Department of Finance recorded transfers (BBL 3-02684-7503; each condominium apartment is its own tax lot).

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.
