812 Sir Galahad Lane
Lewisville, Texas 75056-5717

County: Denton Castle Hills Ph I Sec C

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.
