Constructed as a build-to-suit for a private corporation, phase one of this development provides over 320,000 gross square feet of office connected via an enclosed pedestrian bridge to structured parking for approximately 1,100 cars. The project capitalizes on its urban location with a twelve-story tower culminating in a back-lit architectural feature that serves as a backdrop to the dramatic water fountain on Legacy Circle. An interior exit stair serves as a monumental communicating element throughout the building with glass guardrails and class ‘A’ finishes.


Design must yield a return. It might be a return on investment, delighted tenants, improved wellness, or a more enjoyable workspace. That return — the return on our deep experience — is what the Corgan team makes possible.

The experience of creating great places should be as thoughtful, energizing, and engaging as the space itself. By putting our client’s objectives at the center of every decision, Corgan designs inviting environments that achieve goals and build meaningful value.

We approach each opportunity as engaged, open-minded collaborators. We work fast and hard, but keep the process easygoing. Corgan’s deep commercial experience and forward-looking approach mean we respond to client dynamics with speed and agility. We know when and where to spend, and, more importantly, when not to spend. We maximize opportunity and minimize risk and inefficiencies.

At Corgan, the only standard for successful design is a satisfied client.
