Ross Group

The original auto showroom is the most significant interior space of the building. Historic finishes including terrazzo floors, glazed tile walls, and plaster ceilings were restored. To preserve the openness of the original showroom, glass box conference rooms float within the space reminiscent of the vehicles that were once displayed there. Historic photos of International Harvester trucks clad each conference room marker wall.

An existing service bay was converted into the company fitness room, and a second for the president’s office.

The daylight-filled machine shop and parts warehouse behind the showroom was the perfect enclosure for the flexible, collaborative office environment.

The large bowstring trusses were cleaned and painted to accentuate the laciness of the historic bolted steel members.

In addition to preserving the history of the dealership, modern innovations were included. The building’s energy needs are met by geothermal wells under the parking lot and solar panels on the roof, making this Historic Preservation project one of Tulsa’s most sustainable buildings.
