The Colony sits along the south shore of Lake Lewisville in Denton County, bordered by Lewisville, Frisco, and Little Elm. It is one of the older planned communities in the DFW area, with much of its core development dating to the 1970s–1990s, alongside newer lakefront and mixed-use developments near the Nebraska Furniture Mart and Grandscape entertainment complex. That mix of older established neighborhoods and newer premium developments creates a diverse solar market with good economics across the city.
