Primary Building Materials of the White House
The White House is primarily constructed from sandstone blocks. The exterior walls use Aquia Creek sandstone, which was quarried in Virginia. This stone provides a durable, light-colored facade that has defined the building’s appearance for centuries.
Interior Materials and Structural Components
Inside the White House, builders used brick for interior walls and structural supports. The original construction also relied heavily on wood for flooring, roof framing, and interior paneling. Over time, renovations introduced modern materials while preserving the historic look.
Coatings, Paint, and Protective Treatments
The White House is famously painted white, a practice that began after early repairs and later became standard. Protective coatings help shield the sandstone and wood from weather damage.
