Built in 1924, this one-story, flat-roofed building measures 25'-0" x 30'-0". It is constructed of brick masonry set on a concrete foundation. Despite its modest size, this small building has classical
overtones. Stylistic features include variation in brick color and regularly spaced brick pilasters. The main (south) façade is faced with variegated, light-colored brick laid in a stretcher bond pattern.
Stringcourses of darker, solid-colored soldier bricks add interest and contrast to the façade. The cornice is concrete and extrudes downward slightly beyond the wall's top edge. A second identical treatment
relieves the space between the cornice and the window and door openings, creating a double-awning effect. The building is accessed by a wood-frame, twelve-light door with matching sidelights capped
with transom windows, all of which appear original. A brick pilaster separates the doorway from the adjacent window, which features an identical transom. A fixed-light, aluminum window has replaced
the original glazing (which probably matched the present doorway treatment in appearance) beneath the transom.
The historic Interstate Telephone Company building has experienced minimal modifications and is very well preserved. It exhibits excellent exterior integrity, and is reflective of growth of the commercial core in response to changing technologies during the 1920s. Today it is known as the Office Services Building.
