A 229,000ft2 wing was added to the building's northwest corner in 1935–36, changing what had been an L-shaped building to a roughly U-shaped one. The building has nine floors plus a basement. The 4th through 9th floors were used almost exclusively as warehouse space, while most portions of the 2nd and 3rd floors functioned as office and mail-order workspace. The first floor was used primarily for loading and unloading of freight arriving and leaving by truck or rail and temporary storage of such goods. Three rail spurs served the facility, extending into the ground floor. Among other things, the building is known for its large steel-framed roof sign, the largest sign in Portland, which was constructed in 1925.
