  • This office building sits on a one-acre city block adjacent to Klyde Warren Park in Downtown Dallas. Because of site restrictions, the office building lives on top of the parking garage--creating a taller building with greater presence along Woodall Rodgers Freeway, and maximizing views for the office space (the lowest office level is nine floors up). OMNIPLAN proudly officed on the 15th floor for 19 years and then moved to the 16th floor in 2020.

Life in the Community

The cities we work in are more than just work for us. Architecture and design can bring balance and happiness to people's lives. We take pride in the work we do because, as community members, we have a responsibility to continue to help shape the industry and livelihood of each city we work in. This philosophy is evident in everything we do. It's what drives our culture and ultimately our craft and how we approach each project.
