The Mill recently marked the completion of a recent expansion of its coworking space at Market West, 221 W Tenth St. in downtown Wilmington.

The 38,000-square-foot expansion makes The Mill one of the largest coworking spaces in the Greater Philadelphia market. The expansion was part of the mixed-use conversion of the former Nemours Building now known as Market West.

The Mill expansion to the third floor includes more than 30 furnished offices of various sizes ranging from a single workspace to a 5,500 square-foot suite. The third-floor space also features outdoor terraces, a video and audio podcasting suite in partnership with Studio Charter, and wellness spaces like the treadmill and maternity suites.

New community spaces offer recreational activities such as shuffleboard, foosball, and cornhole as well as a multi-purpose party room that can accommodate up to 30 people. A glass interior stairwell now connects the third and fourth floors so members can take advantage of existing amenities and conference rooms.

The Mill first opened at Market West in April 2016, occupying 13,000 square feet on the fourth floor. Since then, The Mill also took over management of the 221-seat auditorium at Theater N that shows arthouse films weekly and can be rented by Mill members for meetings and events.


The Mill manages a second suburban location at The Concord off Silverside Rd in Wilmington, which opened in January 2020. The Mill at The Concord features a 20,000 square-foot indoor/outdoor space with 32 offices and community space. The Mill plans to expand further south with a new location in Seaford at The Nylon Capital Center by 2025.

“It’s remarkable to reflect on our journey from The Mill’s humble beginnings, occupying just 13,000 square feet on the fourth floor in 2016, to our current standing with expansions in the suburbs like the Concord Plaza, and now the third floor. We’re excited for what we’re planning in Seaford and beyond. It has been a privilege having a front row seat over the years watching some of the state’s most exciting startups and small businesses grow.  It’s reminiscent of witnessing the evolution of a city, which is precisely what I envision for a thriving co-working space – filled with diverse businesses, essential amenities, and ample opportunities for businesses to grow and adapt over time,” said Robert Herrera, founder of The Mill.

“When we looked for a location for the Delaware Prosperity Partnership offices, The Mill offered us a flexible spot that allowed DPP to project a polished presence to our customers and partners as well as being proximate to the entrepreneurial vibe and activity that Mill members create,” said Kurt Foreman, CEO of the Delaware Prosperity Partnership  “When we had the chance to shift to the new third-floor portion of The Mill, doing so was a no-brainer. The space’s well-designed, sleek feel conveys a positive liveliness and image, contributing toward our team achieving its goal of growing the state’s economy.” — Kurt Foreman, President & CEO, Delaware Prosperity Partnership

The former Nemours Building is being converted to Market West by the owners the Buccini/Pollin Group in a $100 million mixed-use redevelopment that will allow future tenants to live, work, and play all within the heart of Downtown Wilmington, a release stated.

“The Mill is the embodiment of what we are trying to do here at Market West. By bringing together businesses of all sizes and industries in highly amenitized spaces that extend beyond the office walls, we can attract a skilled and innovative workforce to downtown Wilmington,” said Chris Buccini, founder of the Buccini Pollin Group. “I’m so proud of Rob Herrera and the entire Mill team, who have continued to prove that coworking is more than a trend, but rather an exciting workplace solution that appeals to both start-ups and more established firms.”
