Property Description
Discover a rare Land only opportunity in the heart of the fully developed, master-class designed, luxury subdivision, known as the one and only Castle Hills Estates. The best of the best available only in the rolling hills of Castle Hills In Lewisville. A beautiful homesite close but not too close to numerous employment centers, capable of supporting a 15,000+ sqft home. And perhaps more unique, a topography that allows for a basement. So think showplace, like a 6+ car garage. Add an elevator and observation deck and watch multiple firework shows. Dreaming of an indoor court? Not a problem. Although you can easily walk to such amenities within the community. The lot is ready to go. Utilities are ready. Just design your dream home; or start with plans already designed. No specific custom builders or specialized architect is required. Although a referral can be made if requested. A one-of-a-kind property, both now and going forward. Think generational. The vision for the surrounding area is phenomenal. The front of the home site faces a beautiful four+ acre lake, parks, and green space leading to a beautiful golf course. Literally steps to other parks and trails, and neighborhood shopping and dining. Part of a well-designed master-planned community brimming with artistic opportunities. An opportunity to be a resident of a community that is truly a gem. Visualize relaxation, at-home and at nearby one-of-a-kind entertainment centers. Access to DFW's best places. Great schools, shopping, dining, everything. Quick access to airports (big and small), and numerous recreational and entertainment amenities. Buy this lot and build at your pace. No country club membership is linked to property, but membership to a great private golf course and country club can be chosen for social, golf, or tennis memberships. It's truly an exceptional build opportunity in the heart of Castle Hills, the center of the DFW metroplex.
