Let’s Talk

Three Box is located in the Eastside development on the southeast corner of Highway 75 and Campbell Road in Richardson.

If traveling east on Campbell Road from Highway 75, turn right on Lakeside Boulevard into the Eastside development. Our building, Eastside Centre, will be on your right, and visitor parking is available in front of the main entrance. Additional visitor parking is available on the north end of the building.

Three Box strives to be a safe, welcoming place for everyone – which includes making our office easily accessible. Our building, Eastside Centre, has accommodations for individuals who may need assistance.

Ramps are located at both the primary entrance on the east side of the building, as well as the secondary entrance on the west side. Elevators are located at the center of the main floor. Signage is equipped with Braille, including at the entrance to the Three Box suite.

If other accommodations would make it easier for you to reach us, please contact our team before your visit. We’ll be happy to help.
