Residential Land for Sale in Lewisville, Texas
812 Sir Galahad Ln, Lewisville, TX 75056
A Rare Land Only Opportunity in Castle Hills. Discover one of Castle Hills' premier homesites - a beautiful, oversized lot in the rolling hills of eastern Lewisville. Situated 15-20 minutes from major employment centers, this property provides the ideal balance of privacy, convenience, and long term investment. The homesite is large enough to support a 15,000+ sq ft custom residence, and can accommodate a full basement. So, imagine the possibilities: a 10+ car garage, an entertainment level, a safe room, an indoor court, an elevator to an observation deck with great views. Build now or take your time - there's no requirement to start immediately, and no restrictions on builders or architects. Customized plans are available upon request. The site itself faces a serene 4+ acre park with a small lake and gazebo, and is only steps from additional parks, trails, and a beautiful golf course. Shopping and dining are just blocks away, with only minimal daily street traffic. Truly, it's an exceptionally master-planned community throughout. The community, not really just a neighborhood, with numerous world class amenities, top tier schools, extensive entertainment options (including a soon to be built nearby indoor snow ski slope), and unmatched surrounding infrastructure. Multiple world-class airports are less than 30 minutes away. Additionally, an optional membership to The Lakes at Castle Hills allows access to golf, tennis, pools, and a long list of social functions which are all recognized as being great, at a well-known, up and coming golf club and community center. The list of amenities is impressive. Again, this is a once in a lifetime chance to build a generational home in one of DFW's most desirable and dynamic communities - today the population center of the metroplex, and tomorrow a cultural hub. We are local experts and happy to share what's ahead in Castle Hills.
