Meet Mabel: MAG Partners unveils renderings of new residential project in Chelsea + NYC rentals under $2,500/month

Thursday, Apr 10, 2025 By CityRealty Staff, CityRealty contributor

In early April 2025, MAG Partners, the real estate developer founded by MaryAnne Gilmartin, unveiled new renderings of Mabel, its latest residential project. The seven-story building, rises from a prominent site at 335 Eighth Avenue at the corner of West 26th Street. The red-brick building brings a context-sensitive design by COOKFOX to its Chelsea neighborhood, but its all-electric infrastructure will be instrumental in its quest for LEED Gold and Passive House certification.

MAG Partners developed Mabel in conjunction with Safanad and Met Life Investment Management under the Affordable NY program. Thirty percent of the 188 units have been designated affordable for low- and middle-income New Yorkers.

Details are not yet available about the apartments' interiors, but first renderings show large operable picture windows that fill the spaces with natural light. Residential amenities are set to include a fitness center, a library, a media lounge, a coworking lounge with private workspaces, and a dining area with catering kitchen. Additionally, in accordance with COOKFOX's commitment to biophilic design principles, Mabel will be topped with outdoor roof gardens with grilling and dining areas.

Mabel is named in honor of Mabel Osgood Wright, a New York City writer and early conservationist, in the spirit of MAG Partners naming its residential buildings in honor of historic women. It is located around the corner from Ruby, MAG Partners' first residential project named in honor of fashion designer/Harlem Renaissance figure Ruby Bailey. (No word yet on who the namesake for 300 East 50th Street will be, but this MAG Partners-helmed project is estimated to open this summer.)

Mabel is also located in excellent proximity to Hudson Yards, Madison Square Garden, the High Line, Fashion Institute of Technology, and many acclaimed Chelsea restaurants. Nearby public transportation options include the 1, C, and E trains at 23rd Street, and it is also situated down the street from Moynihan Train Hall.

Mabel rose as the replacement of an aging building at the limited-equity Penn South cooperative located between Eighth and Ninth Avenues and spanning West 23rd to 29th Streets. Under the terms of Mabel’s ground lease, MAG Partners will pay rent directly to Penn South in a move that keeps the complex affordable for current and future residents.

Moreover, as the old building housed a Gristedes supermarket in its retail space, the developer agreed to include a replacement supermarket in the new building. As such, Mabel's ground-floor commercial space will include a grocery store operated by Lidl, a high-quality European-based grocery store.
