Architectural Drawings of the White House
The White House architectural drawings document the evolution of the executive residence from James Hoban's original 1792 design through multiple renovations. The National Park Service maintains historical plans showing the neoclassical structure's evolution, including the 1814 rebuilding after the British burned the building during the War of 1812. The current West Wing and East Wing additions required separate engineering drawings integrated with the original structure. The Architectural drawings are stored at the Library of Congress and the National Archives, with digitized versions accessible for research purposes. The main residence contains approximately 55,000 square feet across 132 rooms across 6 levels, a layout documented in detailed floor plans maintained by the National Park Service official White House history.
James Hoban, an Irish-born architect, won the design competition in 1792 with a plan inspired by Leinster House in Dublin. His original drawings specified a sandstone façade with three floors, a central dome later removed, and symmetrical wings. The 1902 McKim, Mead & White renovation removed the Victorian additions and restored the Georgian appearance based on Hoban's original drawings. The 1948 Truman renovation involved structural drawings that added a steel frame inside the existing walls while preserving the exterior stone. The current West Wing, designed by Nathan C. Wyeth in 1909, added office space separate from the residence with its own set of architectural drawings on file with the General Services Administration.
Construction Costs and Budget Figures
The original construction cost of the White House from 1792 to 1800 totaled approximately $232,372, equivalent to roughly $4.8 million in modern dollars according to inflation-adjusted calculations.

The 2025 federal budget allocation for White House maintenance and operations falls under the General Services Administration appropriation, with specific line items for structural upkeep and historic preservation. The East Wing renovation completed in 2015 cost approximately $3.8 million for structural and security upgrades. The National Park Service publishes annual maintenance expenditure reports detailing costs for preserving the historic building's integrity GSA historic preservation.
The 1902 renovation under Theodore Roosevelt cost approximately $500,000, or roughly $17 million in today's dollars. The 1961 Kennedy restoration, funded through private donations coordinated by the White House Historical Association, spent approximately $1.5 million on furnishings and decorative arts. The 2023 White House budget request included $12.6 million for the Executive Residence maintenance and preservation programs. The total cost of all major renovations combined exceeds $100 million in nominal dollars. The General Services Administration manages the White House property portfolio, which includes the Executive Residence, West Wing, East Wing, and ancillary buildings across the 18-acre grounds.
