Due to its advanced age, the House of Representatives is in the early planning stages for a top-to-bottom renewal of the Cannon House Office Building. The AOC has assembled a team of in-house experts and consultants who are working with House leaders to define key aspects of the project. This initial effort will better define the estimated costs, scope of work, and potential timeline for the work. The AOC expects this initial planning to conclude in 2012.
