The home of Susan Simons and John Hagerty presents an untraditional profile in its Mount Pleasant, S.C., setting, and it reveals even greater surprises upon a closer look. The facade of the house is cedar presented in a playful variety of forms, painted and unpainted, with windows of varying sizes finished in a bold green trim. One side tilts outward from the ground. Most notable are the multiple oak trees poking through the four decks of the 4,036-square-foot, three-story home, earning it the name the Tree House.
