Norfolk, Virginia native Alan McCullough Jr. (c.1909 – July 13, 1993) was a 20th-century modernist architect who found popularity after World War II for his Virginia residences. His work in Richmond, Norfolk and the Northern Neck married modern design and planning with local elements like colonial brick and buff-colored mortar. Like other regional architects such as Virginia Beach's Lewis Rightmier, Richmond's E. Tucker Carlton and Alexandria's Charles M. Goodman, McCullough took the open plans, striking geometry and low profiles of houses by Frank Lloyd Wright and built houses with regional elements appropriate to Virginia's climate and history. McCullough's trademark features includes terrazzo floors and raised fireplaces with levitating hearths.
