A once-in-a-generation opportunity to own one of the Texas Hill Country's most extraordinary private compounds. Offered together, 475 and 503 Happy Trl span approximately 16 breathtaking acres, combining two architecturally distinct residences into a legacy estate designed for entertaining, recreation, multigenerational living, and complete privacy. At 475, everyday life feels like a private resort. The approximately 8,000-sqft estate features a contemporary main residence, a Party Barn, a private guest apartment above the five-stall horse barn, and extensive garage space for car collectors, RVs, boats, or hobbies. Beyond the homes, the property unfolds into a resort-style landscape with a pool and spa, pickleball court, stocked fishing pond, walking and UTV trails, seasonal creeks, raised garden beds, open pasture, and beautifully maintained grounds. Equestrian enthusiasts will appreciate the five-stall luxury barn with individual turnouts, fenced riding arena ready for completion, and dedicated pasture space. Just beyond, 503 offers a serene escape from the fun next door. Recently completed, the approximately 3,800-sqft MCM inspired residence sits atop 7 private acres, where walls of glass frame panoramic Hill Country views. Warm contemporary finishes, an entertainer's kitchen, and seamless indoor-outdoor living create a peaceful retreat that perfectly complements the recreational lifestyle found next door. Together, the properties offer more than 11,800 sqft of living space and an unmatched combination of luxury, flexibility, and natural beauty that is nearly impossible find in the Hill Country. Whether envisioned as a private family compound, luxury retreat, equestrian estate, or legacy property for generations to come, it stands in a class of its own. Sellers prefer to convey both properties together but will consider selling separately. Additional photos, videos, floor plans, and property details are available on the dedicated property website.
