Plaza 21

The original program included one-bedroom apartments beginning around 520 square feet and two-bedroom homes extending beyond 1,100 square feet. Private balconies were offered in a range of sizes, including larger outdoor areas attached to selected homes. Open living and kitchen arrangements form the basic interior organization.

The design uses brick and masonry outside, with a tall entrance space leading into the lobby. Durukan Design worked on the interiors. Nine-foot ceilings were part of the original apartment specification, giving the low-rise building a different interior proportion from older walk-up housing nearby.

The inventory includes layouts with distinctly different total areas. A smaller one-bedroom and a larger two-bedroom do not carry the same balance of living space, sleeping rooms and outdoor access. Balcony dimensions also vary enough that the outdoor component should be considered independently of the apartment's bedroom count.

The common facilities include fitness and bicycle space, refrigerated storage and video entry. Parking and storage were offered separately in the original development. Parking and storage being in the building doesn't mean either one transfers with any particular apartment.

DOF places the residences in Tax Class 2 and the nonresidential lots in Class 4. The residential class has no statutory cap on annual assessment growth. Common charges and the individual apartment's real estate taxes are separate carrying-cost components.

The commercial ICIP/ICAP benefit began in 2011 with a 25-year term and is active on the 2027 roll. The residential 421-a program began in 2012 with a 15-year term but is not active on that roll. The different programs and start dates are material because a mixed condominium can retain one benefit after another has ended.

The building's recorded FAR exceeds the current R5 residential allowance. This is a description of the existing floor area relative to the zoning figure, not a basis for assuming that additional residential space can be created within the condominium.

Market read. Most recent trades (2025) cleared a median $801/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 2.8% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

Sales sourced from NYC Department of Finance recorded transfers (BBL 4-00881-7501; each condominium apartment is its own tax lot). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage from recorded condo declarations and offering plans.
