Large media/game room, solarium, screened porch, gym, indoor spa room and a heated 3 car garage. The roman-style gunite pool is the focal point of the back yard. Separate guesthouse with studio/office, pool cabana, 2 full baths and heated 2 car garage. Classic Turf tennis court with lights for evening play.
