Wilmington-based 9th Street Development Company is redeveloping the long-vacant Nylon Capital Shopping Center in Seaford, Delaware, with plans to open a new location of its coworking space The Mill as the anchor tenant. The $60 million project will also bring in other tenants like Delaware Technical Community College, TidalHealth, and Vanderwende's Ice Cream, revitalizing the former DuPont factory site.

Why it matters

The Nylon Capital redevelopment project represents a major investment in Seaford's economic future, transforming a long-neglected site into a mixed-use campus that will bring new jobs, services, and community amenities to the area. The addition of The Mill coworking space is particularly significant, as it will provide flexible, technology-enabled workspace to support local entrepreneurs, remote workers, and small businesses in a region that has historically struggled with connectivity challenges.

The details

The Mill location in Seaford will mirror the company's existing coworking spaces, offering flexible memberships, private offices, and shared amenities like conference rooms, a podcasting studio, and high-speed internet. The broader redevelopment of the 243,000-square-foot, 21-acre Nylon Capital site also includes plans for other tenants like Delaware Tech, TidalHealth, and Vanderwende's Ice Cream. The $60 million project was made possible through a combination of private investment and $3.1 million in funding from the City of Seaford, $20 million from the federal American Rescue Plan Act, and at least $2 million from the state.

  • The Mill is expected to open in the coming months.
  • The broader Nylon Capital redevelopment project has been in the works for several years.
