"The scheme preserves the historical axis and existing street pattern. It mediates the European formality of the L'Enfant Plan, the naturalism of Andrew Jackson Downing's Lafayette Park, and the informality of the White House grounds. It is a scheme that values continuity with its surrounding context, using familiar materials to create a place that is timeless and a setting where virtues of democracy will continue to thrive."
