Port San Antonio wants a landmark, and it hired a landmark architect to get one. The public campus on the city’s southwest side, built on the former Kelly Air Force Base, is planning a $275 million, 12-story office tower designed by Pelli Clarke & Partners, with a possible groundbreaking in 2026. It would be the tallest and most visible piece of a tech campus that has grown quietly for years.
Project Scope
The tower is meant to house the aerospace, cybersecurity, defense, and advanced-manufacturing tenants clustering at the Port, giving them Class A space on a campus that already runs its own rail, utilities, and airfield access. At 12 stories it’s tall for the neighborhood by design, a deliberate signal that the Port is a destination rather than an industrial back lot. Pelli Clarke & Partners brings the profile; the Port brings a rare thing in commercial real estate, a single owner controlling a large contiguous site.
Why It Matters
San Antonio’s tech and defense economy has outgrown scattered office parks, and the Port has positioned itself as the place to consolidate it. A signature tower does two jobs: it adds the square footage tenants need, and it gives the campus an identity that recruits talent and companies. Whether the office bet lands in a soft national market is the open question, but a public owner building for a specific, growing tenant base is a safer version of that bet than most.
