The full picture AI research · Nov 1, 2026
A developer proposed replacing an existing office and warehouse building at 3200 Horizon Drive, in the Renaissance Park area of King of Prussia, with a two-story data center. The county record describes about 370,900 square feet of new buildings, including a central utility plant, on 10.3 acres. The old building would be demolished and parking reduced.
The site was one of five data center sites proposed by the same developer in Upper Merion, covering more than 4.5 million square feet in total. News coverage describes strong public opposition, including a petition with over 20,000 signatures. The township planning commission recommended rejecting several of the plans. On August 13, 2026, the Board of Supervisors voted to deny the plans for all five sites. Reasons reported include concerns about pollution, energy use and electricity rates.
The developer has said it plans to appeal. No end user or tenant was identified in the sources found.
