Five Key Insights from the Report

1. King of Prussia remains the region’s largest and most resilient suburban office market.
   With approximately 7.8M SF of office inventory, UMT/KOP surpasses peer markets including Malvern (7.3M SF), Wayne (5.7M SF), Conshohocken (5.2M SF) and Exton (4.6M SF). It also posts the lowest vacancy rate among these markets at 11.3% in Q1 2026.
2. Demand for Class A office continues to outperform.
   Despite broader softening tied to hybrid and remote work, asking rents continue to rise, reaching $29.09/SF overall and $34.14/SF for Class A office space. The divergence between rising vacancy and increasing rents suggests that tenant demand is consolidating around well-located, amenity-rich buildings that offer high-quality workplace experiences.
3. Redevelopment is actively reshaping underutilized office space.
   As workplace needs evolve, underperforming office sites across UMT/KOP are being repositioned through full-site redevelopment and adaptive reuse. Projects converting former office properties to residential, logistics and digital infrastructure uses are helping modernize the market while supporting broader economic growth.
4. King of Prussia serves as a regional center for aerospace and defense operations.
   Industry leaders including Lockheed Martin, Arcfield, Peraton, KBR collectively occupy about 600K SF of office space and support more than 3,000 workers. The concentration of aerospace and defense companies strengthens the market’s employment base and reinforces its strategic importance within the region.
5. Amenities and accessibility remain major competitive advantages.
   Commercial real estate leaders from CBRE, Newmark and Brandywine Realty Trust point to King of Prussia’s unmatched combination of regional accessibility, dining, retail and lifestyle amenities as a key differentiator. The market’s location at the intersection of major transportation corridors, combined with its walkable destinations and growing mixed-use environment, continues to attract employers seeking to recruit and retain talent.
