On Location Portraiture


As part of the 147 acre, mixed use Frisco Square, this five story building was designed to meet the city’s architectural style guidelines for the development. Using responsible design measures, O’Brien was able to keep costs within constraints for the client. Clad in brick with a tower feature for architectural prominence, the building features ground level restaurant space with upper floors dedicated to offices – Gearbox Software occupies the top three stories. The building offers a prominent location with great exposure in a walkable area. The amenity rich design includes a full service fitness center, spacious and efficient floor plans, large windows with generous ambient light, high ceilings, plentiful elevators, and a detached seven-story parking garage, giving the building a competitive edge for leasing.
