Designed by SOM’s Houston office, this fifteen-story office building with a triangular footprint and round corners is faced in alternating bands of mirrored glass windows and buff brick spandrels. Vertical reveals between the curved ends and the flat sides create a visual effect of monumental pilasters at the corners. The siting of the building and its rectangular concrete parking garage create a small, triangular, paved courtyard.
North of the Briercroft Building are the horizontally elongated, two-story Honolulu Oil Corporation Building (1949, John Ekin Dinwiddie and Richard Maxwell; 204 W. Illinois Avenue) and the five-story, curtain wall-clad Midland Municipal Administration Building (1960, Martin and Lemmon; 119 W. Illinois).
