Prosper Property Group makes construction progress at 10W17

Manhattan, NY Prosper Property Group has construction underway at 10W17, a boutique condominium development located at 10 West 17^th St. in the historic Flatiron District. The developer has selected SERHANT. New Development to lead exclusive sales and marketing for the project.

Located within the Ladies Mile Historic District of Flatiron between 5^th and 6^th Ave., 10W17 is a new condominium building that celebrates the city’s history of ingenuity and invention. Rising 17 stories, 10W17 will feature 34 luxury condominium residences, from one-to-three-bedroom homes, including penthouse residences, complemented by more than 2,000 s/f of curated amenity spaces designed to enhance modern urban living.

“10W17 reflects our commitment to delivering architecturally distinctive residential projects that are deeply connected to their surroundings,” said Eddie Bender, CFO at Prosper Property Group. “The area is one of Manhattan’s most historically rich neighborhoods, and this building has been thoughtfully designed to celebrate its legacy while introducing a contemporary residential offering in the heart of Flatiron.”

Designed by DXA Studio, 10W17 draws inspiration from the historic relationship between fashion and architecture that defined the Ladies’ Mile district during the late nineteenth century. Construction activity by First Standard Construction is currently underway at the site, with excavation and foundation work progressing. Structural construction is expected to advance later this year as the reinforced concrete superstructure begins to rise.

The development sits in the Flatiron District, within proximity of Union Square, Madison Square Park, and multiple subway lines. 10W17 is expected to be completed in spring 2027. 

10W17’s street façade will be composed of ultra-high-performance concrete panels sculpted to evoke the appearance of flowing fabric, referencing the neighborhood’s origins as the center of New York City’s garment industry. Approximately 200 UHPC panels will form a layered façade system mounted on a rainscreen assembly designed to improve the building’s thermal performance and energy efficiency. The building will exceed current energy code requirements and will utilize all-electric building systems.

In the late 1800s, the Ladies’ Mile district was home to some of the country’s earliest department stores and garment manufacturers, employing tens of thousands of workers in nearby loft buildings producing some of the first mass-produced clothing in the United States. At 10W17, these historical influences are translated into a contemporary architectural expression, bridging the district’s design legacy with a modern residential experience.
