The Dilbeck original in Hillcrest Estates overlooks a private lake with ducks and turtles galore. The residence was extensively remodeled and expanded by Diane and Daryl Johnston in 2003. The 7,364-square-foot interior is loaded with every amenity: terraces, huge bar, and four living areas, including game, media, and wine-cellar rooms. It also has five bedrooms, five and a half bathrooms, and a pool with cabana retreat. Missy Woehr and Cathy Anderson for Allie Beth Allman & Associates.  972-381-6826.
