The Forest Oil Building is a three-story office building raised on columns to provide covered ground-level parking. Grooves and plugs from the formwork show on its cast-in-place concrete exterior. Three-story columns project slightly from the plane of the spandrels. The perimeter of the building extends to the sidewalk lines, but on the interior, sheer walls zigzag around an irregular sheltered court with a small garden.
John Dorn, a Pennsylvanian transplant and an officer of his family-owned Forest Oil Corporation, was one of Frank Welch’s first clients after Welch moved to Midland in 1959. Welch designed his most celebrated house, The Birthday (1965), for Dorn and his wife, BLee, on their Sterling County ranch (destroyed c. 1998 by new owners).
