The firm was a leader in the modernist tower block design at the time of construction which believed in three principals: heavy metal anchoring, profuse windows for air and light, and simple muted dark colored facade paneling that gave their landmark buildings a "natural" organic look. It is located at 1100 Superior Avenue along East 12th Street. In 1994, during a water main break, a four-story section of the Diamond Building lost some of its glass from pressure of the water. In 2012, the tower's naming rights were purchased by insurance brokerage the Oswald Cos. (which is written in bright red multistory letters on the north and south sides of the tower), one of its largest tenants.
