Willowbrook renovated this four-story historical building on the Oklahoma State University campus in Stillwater, Oklahoma. The project consisted of the interior and exterior renovation of Social Sciences and Humanities (Murray Hall) from the existing five-story residence hall into offices, classrooms, laboratories, a 146-seat sub-grade tiered lecture hall with a rooftop terrace and support spaces for the College of Arts and Sciences. The renovation included work in four stories and a subgrade basement.
