Greystar, a national apartment developer, proposes to tear down an office building at 720 Vandenburg Road in King of Prussia. In its place it would build a six-story apartment building with 205 homes on about 6.85 acres. The plans also include parking, sidewalks, utilities, landscaping and stormwater controls.
The site now holds an office building. A September 2025 news report said a government contractor leases it and that the lease is nearly up. The developer's application calls the building outdated for today's office market. The report also described a pool, a clubhouse and a surface parking lot of roughly 300 spaces. No organized opposition was found in the sources reviewed.
Township agendas show the project going through a conditional use application and a land development plan review in 2026.
What it could mean nearby
- Adds 205 rental homes in a part of King of Prussia that is already a mix of offices and apartments.
- Replaces an office use with residential use, which usually changes the timing of traffic, with fewer jobs on site.
- The site sits near the Schuylkill River Trail, which a news report noted. The plans include landscaping and stormwater systems.
- The county planning commission's review letter was reported as generally supportive of the proposal.
Where it stands
Township agendas from spring and summer 2026 list a conditional use application and a land development plan for the site, but no final approval was confirmed in the sources found. Typical next steps are a decision by the township supervisors, then final plan approval, permits and demolition before construction.
