Noted Palm Beach architect Marion Sims Wyeth was unanimously chosen by both the Cabinet and the Governor's Mansion Advisory Committee to design the new home. Wyeth was told to use Andrew Jackson's home in Tennessee, The Hermitage, as a model for the exterior. However, due to a shortfall in the state's budget, the completed home had fewer rooms than originally planned. Including furnishings, the new mansion cost $350,000 and was completed a year later, in 1956. The first governor to live in the new mansion was LeRoy Collins, in the spring of 1957. Collins and his wife were actively involved in the new house's construction, and in 1957, they suggested to the state a Governor's Mansion Commission. In 1979, First Lady Adele Graham, the wife of Bob Graham, began organizing tours for the mansion. The next year, she founded the Florida Governor's Mansion Foundation. The contributions of this foundation helped to make possible the first addition to the Governor's Mansion since 1957, the Florida Sun Room. The foundation was created to solicit private funding for the restoration of the mansion, its furnishings, and its grounds.
