The Dudley Spencer House, also known as Laurel, is a Frank Lloyd Wright-designed Usonian residence in Wilmington, Delaware, created in 1956 as part of his effort to shape modern homes in close harmony with nature. Its hemicycle plan, irregularly coursed fieldstone walls, flat roof, curving extensions, and window bands beneath the roofline reflect Wright’s late residential style, while the fireplace and hearth anchor the interior. Built over five years from 1956 to 1961 for Dudley Spencer, the house was later recognized on the National Register of Historic Places in 1974. It remains a private residence not open to the public.
