About This Home
This is one of those opportunities that rarely comes to market, and when it does, it’s recognized for what it is: a true legacy property. Set on approximately 2.19 acres along the main body of Lake LBJ, this property offers an extraordinary 311 feet of waterfront—an increasingly rare combination of scale, privacy, & presence on one of the most sought-after stretches of the lake. The setting is both peaceful & expansive, w/wide open water views framed by a canopy of mature trees that provide natural beauty, shade, & a sense of seclusion that is difficult to replicate. The existing home on the property is livable & could be enjoyed as-is or updated over time. However, the true value here lies in the land itself—its size, frontage, & the flexibility it offers for the future. Whether that vision is to create a private waterfront estate, design a multi-generational family compound, or explore the potential to subdivide into multiple homesites (buyer to verify), the possibilities here are compelling. The property was originally platted as three lots, adding an additional layer of flexibility for those considering long-term use or investment. One of the property’s most unique features is its own small island just off the shoreline-an uncommon detail that gives the setting a true sense of character & place, creating an experience that feels distinctly your own. Life on this stretch of LBJ centers around the water, from quiet mornings under the trees & glassy conditions for skiing or paddling, to afternoons spent boating & gathering with family/friends. Evenings bring sweeping Hill Country sunsets across the main body of the lake. With constant water levels & unobstructed views, the property offers both beauty & usability, all within easy reach of every day conveniences. Properties with this combination of acreage, main body location & 300+ feet of frontage are exceptionally limited! This is an opportunity to secure a piece of Lake LBJ that can be enjoyed for generations.
The moment you turn onto Castlehigh Drive in Granite Shoals, the world shifts. Three hundred eleven feet of Lake LBJ waterfront stretches across 2.19 acres in the Granite Shoals subdivision, a property that has spent decades waiting for someone to recognize what it truly is: a private sanctuary on one of the Hill Country's most coveted lake stretches. Listed at $2.95 million ($1,397 per square foot), this is land first, house second. The 1969 wood-siding residence sits comfortably on the main floor with three bedrooms and two full baths across 2,112 square feet. It's livable today, functional for immediate enjoyment, but the real story is what surrounds it.
The lot slopes gently toward water, framed by mature trees exceeding forty feet in height. These aren't decorative: they form a natural canopy that creates genuine seclusion while framing unobstructed views across the main body of Lake LBJ. Glassy morning water reflects Hill Country sunsets in the evening. A small private island sits just offshore, a distinctive geographic feature that transforms the experience from "waterfront property" to "your own retreat." The property was originally platted as three separate lots, a detail that opens doors for future development, subdivision, or multi-generational family use. Buyers should verify subdivision potential independently.
Burnet County's Marble Falls ISD serves this location, with Marble Falls Elementary, Middle, and High schools anchoring the district. The Granite Shoals community sits at the intersection of Highway 71 and Ranch Road 2323, positioning you minutes from Marble Falls' downtown and Lake LBJ Marina while maintaining that genuine Hill Country distance from Austin's sprawl. The constant water level and protected main body location make this stretch functional year-round for boating, skiing, and paddling.
What separates this from typical waterfront listings is the sheer acreage paired with frontage depth. Most Lake LBJ properties this size are already subdivided. This one remains intact, offering the rare choice to keep it whole or develop it forward. The existing home provides immediate usability while you envision what comes next. Whether that's a refined waterfront estate, a family compound spanning generations, or something as yet unimagined, the canvas here is genuinely blank. Properties combining 2+ acres, main body location, and 300-plus feet of frontage surface perhaps once per decade on this lake. This one just listed. After 55 years on the market's periphery, 310 Castlehigh Drive is finally available to someone ready to claim it.
