Airside Business Park
A pioneering partnership where union pension capital and Elmhurst’s disciplined stewardship transformed former airport infrastructure into a thriving business campus driving long-term regional value.
Airside Business Park is a dynamic office and flex campus built on the former Pittsburgh International Airport terminal grounds. Today, it spans six buildings totaling more than 460,000 square feet and offers tenants a combination of flexible workspace, ample parking, and meaningful on-site amenities—including a covered outdoor courtyard with gas grills and a fire pit, a fitness center, a lounge and conferencing suite, and walkable green space. With immediate access to the University Boulevard corridor, I-376, and the airport region’s growing commercial hub, Airside provides both regional convenience and everyday usability for its tenants. The property’s scale, versatility, and strong leasing fundamentals continue to make it a pillar of Elmhurst’s long-term investment strategy.

A Union-Rooted Partnership Driving Regional Growth
Airside Business Park represents the origin point of Elmhurst’s long-standing partnership with PenTrust, a Pittsburgh-based institutional investor formed by 21 local union pension funds. This collaboration remains one of the region’s most meaningful economic engines—union capital reinvesting directly into Western Pennsylvania, generating union jobs, and catalyzing long-term commercial growth. PenTrust’s support helped bring Airside to life and has since fueled many of Elmhurst’s most successful developments, creating a full-circle model where local labor, long-term capital, and disciplined development reinforce one another.
Elmhurst also works closely with the Allegheny County Airport Authority, which owns the land beneath Airside and supports the project’s long-term positioning in the rapidly evolving airport corridor. Over the years, Airside has attracted a high-quality roster of tenants—including Michael Baker International, Columbia, Adidas, Columbia, Puma, Titan Robotics, McKesson, Trane, and Trinity Solar—each contributing to job creation, tax base growth, and innovation in the Airport Area. These partnerships underscore Elmhurst’s role as a trusted steward of regional assets, generating value not only for investors but also for Pittsburgh’s business and employment ecosystem.
Long-Term Value Created Through Disciplined, Phased Investment
Airside was an off-market development, awarded through Elmhurst's partnership with the Allegheny County Airport Authority, that required vision, patience, and a long-term approach—traits that have defined Elmhurst’s development philosophy for more than five decades. The property’s location on the former airport terminal presented unique opportunities, but also significant complexities around infrastructure reuse, phasing, and tenant repositioning. Elmhurst’s disciplined underwriting, deep operational expertise, and close coordination with PenTrust allowed the team to develop the campus, introduce Class A office and flex industrial spaces, and stabilize the project through multiple leasing cycles. The result is an asset built to endure—and evolve—alongside the airport region’s accelerating growth.
The Airside project also illustrates the strength of Elmhurst’s partnership model. With PenTrust as the primary equity partner, union pension capital was deployed locally to create high-quality spaces for businesses, generate sustained employment, and drive long-term economic return. This “Pittsburgh reinvesting in Pittsburgh” dynamic remains a core differentiator of the Elmhurst portfolio. As the airport corridor continues to grow—with ongoing investment into logistics, technology, and advanced manufacturing—Airside stands as a proof-of-concept for the kind of durable, place-based value creation that Elmhurst and PenTrust have built together for more than 26 years.
