About our Restoration and Addition Project

Interior Restoration and Garden-Level Wings Addition

The 2006 Legislature passed House Concurrent Resolution 47 authorizing the Capitol Commission and the Department of Administration to enter into agreements with the Idaho State Building Authority to finance the restoration and construction of two 2-story wings on each end of the Statehouse.

Subsequently, a total of $130 million was secured in bonds; McAlvain/Hummel, design/build professionals, was hired to begin work on the wings; and, the design team of CSHQA Architects and Lemley/3DI continue to finalize space-use plans of the existing building.

In his FY08 budget, Governor C.L. "Butch" Otter proposed that only the restoration of the existing Capitol be completed and not the addition of the 2-story underground wings. However, he and legislative leadership eventually negotiated a compromise to proceed with the addition of two, 1-story underground wings and to reassign the use of the first floor of the Capitol to the Legislature rather than to the Executive Branch.
