Today, Delaware Technical Community College officially cut the ribbon on their new Seaford Innovation Center at Nylon Capital Center.

Bringing Delaware Tech on board as an anchor tenant brings our vision for this development to life.

Transforming this property into a hub for regional growth has been a key component to this entire project, ensuring we directly address Delaware’s evolving workforce needs. Spanning over 30k+ SF across two stories, this facility stands as the largest space on campus. The Seaford Innovation Center is focused on hands-on trade training (HVAC, welding), healthcare certifications, and workforce development to support local manufacturing and medical employers across western Sussex County.

Congratulations, and thank you to Dr. Mark Brainard, Justina Thomas, and the entire Delaware Tech team for working with us to complete this project.

Our team at 9th Street Development (9SDC) is proud to announce our first Pennsylvania investment, marking a significant milestone in our regional growth strategy.

The aerial photo below highlights 101 and 128 E. State Street—the former Genesis HealthCare corporate headquarters—which we are officially renaming The Walker. The growth and opportunity taking shape in Kennett Square is incredibly exciting for us. These two landmark buildings truly sit at the corner of Main and Main, right in the heart of a vibrant, walkable downtown corridor already rich with history, energy, and community.

Our vision for The Walker introduces a dynamic mix of uses to State Street. The tallest building at 128 E. State Street is becoming 60 luxury apartments complete with a rooftop deck, fitness center, and lounge. Meanwhile, 101 E. State Street, known for its signature clock tower, remains a hub for premium, fully modernized office and medical space, complete with an upgraded lobby.

At 9th Street Development Company, we can say with certainty that we invested in downtown Wilmington because we believed in the vision of Mayor Mike Purzycki.

Mike gave us confidence to take chances on Wilmington. He believed deeply in the future of this city, and more importantly, he made other people believe in it too. His leadership, encouragement, and relentless focus on revitalization inspired us to invest in the 9th Street corridor and continue building in downtown Wilmington.

Over the years, we had to call on Mayor Purzycki more than once for help, guidance, or support. Every single time, he responded. He encouraged us. He showed up for us. He attended our openings, celebrated our progress, and constantly pushed us to think bigger about what Wilmington could become.

One thing he consistently repeated to us was:
“If you are not growing, you are dying.”

That was Mike. Even after discussing one project, he would immediately ask:
“What else are you working on?” “What’s next?”

He was always challenging people to keep moving forward, keep investing, and keep revitalizing neighborhoods throughout the city.

As an experienced developer himself, Mike loved talking shop. He had a real eye for aesthetics, urban planning, and placemaking. He cared about the details — how streets felt, how buildings interacted with neighborhoods, how development could create energy and momentum for an entire community.

Some of our favorite conversations with him were hearing stories about what he remembered from the 9th Street Block decades ago. He had such a deep understanding of Wilmington’s history and an even deeper belief in its future.

We looked up to him. We valued our time with him immensely.

To us, Mayor Purzycki was more than a public official. He was a mentor, an advocate for small businesses and development, and someone who genuinely cared about the wellbeing and success of all Wilmingtonians and the people willing to invest in their future.

His vision and belief in this city gave many of us the confidence to keep building here.

Wilmington has lost a transformational leader, and we will miss him deeply.
