The new building mimicked the original federal twin-spire structure, in an Art Deco-Gothic Revival architectural motif.

On June 14, 1946, under the administration of then-U.S. President Harry S. Truman, the Federal Government acquired the building at a reported price of $3.3 million.

A Radome for a weather radar was constructed between the towers on a steel skeleton rising above them, creating a landmark until 1995 when it was removed and the service relocated to Norman, Oklahoma, where it became the Storm Prediction Center.

The clock face has since been removed and replaced by large windows for the highest residential living unit within five states.
