401 Matern Ct delivers 6,252 square feet of 2019-built waterfront living on Lake LBJ at $840 per square foot, which puts the scale, finish level, and lake access into clear focus from the start. In Horseshoe Bay, this residential single-family residence sits on a 0.2697-acre lot in Horseshoe Bay, TX 78657, in Llano County, with the privacy of a gated island setting and fast access back to the main body of Horseshoe Bay.

What it feels like to live here is simple: the house is designed for people who actually use the lake and entertain at a high level. The arrival sequence moves through a dramatic courtyard with water and fire elements, then into a glass-heavy main house oriented to cove and Lake LBJ views. The main living area opens wide to the patio with automatic screens, a fireplace, and an outdoor kitchen, so the house works whether the plan is a quiet weekday evening or a full lake weekend. The primary suite stays on the main level, while the upper floor adds guest space, a media room, wet bar, bunk room, covered balconies, and an office with full bath that can flex as another bedroom. A screened boat garage with lift, gym space, storage, detached casita, and a separate theater or arcade room push the utility well beyond a standard waterfront layout.

From a location standpoint, 401 Matern Ct benefits from direct connection to Lake LBJ and quick access out through Bay West Blvd and FM 2147. Horseshoe Bay Resort, the Yacht Club, and the marina sit just minutes away, which matters if daily life includes golf tee times, boat service, dining, or members-only amenities. The Whitewater 360 Sports Club and the Yacht Club Beach Bar and Pool are also nearby, giving this part of Horseshoe Bay stronger lifestyle infrastructure than many Hill Country waterfront addresses. Marble Falls is an easy drive for groceries, medical services, and additional dining.

The hard numbers support the story. At $5.25M, five bedrooms, six full baths, two half baths, 6,252 square feet, and a 2019 build year, this is a large-format modern lake house in one of Horseshoe Bay’s most tightly held waterfront pockets. The source data lists 646 days on market. School district, assigned campuses, and school ratings are not provided in the source data, so those details should be confirmed separately. For buyers focused on long-term use and scarcity, this address lines up with how value tends to hold on Lake LBJ: newer construction, protected water, and limited waterfront supply on Horseshoe Bay.
