The Marx

Dark gray brick surrounds a grid of large window openings. Angled metal panels and canted windows interrupt that grid, giving the façade depth. The window treatment is a consistent part of the building's design, extending beyond its upper-floor terraces.

One-bedroom layouts originally measured approximately 675–714 square feet, and the principal two-bedroom layouts approximately 971–975 square feet. The three-bedroom penthouse was designed with roughly 1,363 interior square feet and a private terrace. Balconies and terraces account for additional variation within the one- and two-bedroom inventory.

The balcony construction incorporates thermal breaks at the concrete connections. Those connections limit the transfer of heat through projecting concrete, an element documented by the component manufacturer as part of the building's envelope design. That detail is about the balcony's structure, not any one apartment's utility bills.

Laundry is accommodated inside apartments. The fitness room looks toward 35th Street, while the main communal outdoor area is on the roof. Private apartment terraces and the condominium's shared roof are separate spaces.

The Marx uses virtual-doorman service and has a fitness room, bicycle storage and a roof terrace with a grill. Parking and private storage supplement the apartment interiors.

A purchase that includes parking or storage needs to identify the additional interest being transferred. A storage or parking interest offered with a resale is part of that transaction's configuration, not an assumption that follows from buying any apartment in the building.

The 421-a benefit began in 2018 and remains active on the 2027 assessment roll. Its 15-year capped structure belongs in the carrying-cost comparison alongside the residential Class 2 assessment, which has no statutory cap on assessment growth. The building occupies nearly the full residential floor area allowed by its C4-2A zoning.

Market read. Most recent trades (2026 to date) cleared a median $1,172/sf (floor-adjusted) across 2 sales. 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 -3.4% over ask.

Sales sourced from NYC Department of Finance recorded transfers (BBL 4-00642-7501; 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.
