Office Buildings Are Losing Ground — What Kennett Square’s Conversion Means

The proposed conversion of a downtown Kennett Square office building into apartments is not just a redevelopment. It shows how the market for downtown office space is changing in smaller boroughs.

A Wilmington-based developer is set to buy two downtown Kennett Square office buildings for $6.6 million and invest about $34 million more into redevelopment. Under the plan, the 100,000-square-foot building at 128 E. State Street would be converted into 60 apartments with ground-floor commercial space, while the 80,000-square-foot building at 101 E. State Street would remain in office and medical use. The buildings were developed by Genesis Healthcare in 1998 and 2008 and are being sold as the company downsizes after its Chapter 11 filing. The residential building already has ground-floor retail commitments from Mayday Coffee Shop and Tinker.

The first question is why office buildings are losing viability in places like Kennett Square. The answer is demand. Hybrid work reduced the need for traditional office footprints, and employers are using space more selectively. In that environment, older downtown office space has to compete with a different use that is often more valuable: housing.

That does not mean all office space is failing. This proposal itself makes that clear. One building stays in office and medical use. The other converts to apartments. The shift is not from “office” to “no office.” It is from generic office space to more targeted uses. Medical and specialized commercial space can still work downtown. Standard office space is the part under pressure.

The next question is what this conversion does to downtown Kennett Square. It adds 60 apartments, which means more housing in a borough where walkability already supports local retail and dining. More residents usually mean more daily foot traffic and more support for businesses beyond office hours. That is the upside.

It also fits the smaller village-style pattern showing up in other parts of Chester County, where housing, retail, and daily services are being pulled closer together into compact areas. Instead of isolated office space or single-use suburban sites, these areas function more like mini-villages built around convenience, foot traffic, and mixed-use economics.

That is what the developer is betting on. Kennett Square is not an isolated office campus. It is a borough center with existing retail, restaurants, and a built-in pedestrian environment. The investment only makes sense if the developer believes more people want to live in that kind of setting and that the ground-floor commercial space will benefit from the added residential base.

So the real story is not just that one building is becoming apartments. It is that boroughs downtown are becoming the solution to housing people want to participate in. Office space is no longer protected just because it is office space. It has to compete with housing demand, mixed-use economics, and the value of a walkable location.
