After a century of use, neglect and countless modifications which eroded the historical character of the building, the Idaho State Capitol Restoration brought the 200,000 SF building back to its former grandeur by restoring the historical elements of the building, preserving the integrity of the existing materials and rehabilitating the spaces for contemporary uses. As the largest non-highway public works endeavor in state history, exterior, interior and site work stabilized the condition of the building and all systems and infrastructure was upgraded addressing life safety and accessibility. Two new five-story stair and elevator towers were incorporated within the existing building footprint at the northwest and northeast corners to provide emergency egress and allow for better building access. The former dark and dreary basement was transformed into a light-filled space now serving as the primary public entrance into the Capitol. The project connects to two new 25,000 SF underground wings which complement the original building while providing additional office and meeting space for legislators, staff, and citizens without changing the overall appearance of the Capitol from the street.
