Requires Federal agencies and the General Services Administration (GSA) to adopt a formal design policy that favors classical and traditional architecture for large Federal public buildings and to follow a set of Guiding Principles when siting, designing, and procuring those buildings. It directs GSA to create a senior architectural advisor role, run or structure competitions and procurements consistent with the policy, notify White House Domestic Policy staff when proposing non-preferred designs (with cost comparisons and justification), and deliver an annual report to Congress on implementation.
