About This Home
Nestled on over half an acre, boasting open water views, minutes from the Horseshoe Bay Resort’s core amenities: not only an idyllic retreat, it’s also an investment opportunity, suited for short-term rentals. Completely remodeled and taken down to the studs, the home provides the epitome of luxury living. Ascend a few steps to the main floor, where you'll be greeted by an open concept living, dining, and kitchen area. Anchored by a majestic stone fireplace, offering panoramic water vistas, the atmosphere is perfect for relaxation or entertainment. The kitchen is a chef's dream, featuring high-end appliances, custom cabinetry with intelligent storage, and a sprawling island ideal for culinary creations. A generous pantry, cleverly tucked into a corner, provides additional storage and convenient access to the garage via its back stairs. The main level also houses the primary suite with captivating water views, a lavish bath, and a library complete with floor-to-ceiling bookcases. Entertainment awaits downstairs on the lake level, with a game room and four additional bedrooms, each with a dedicated bath and direct access to the patio. Three of these bedrooms offer enchanting water views and all can access the boathouse with a boat and jet skis, a new pool, barbecue area, and ample space for alfresco dining. An attached garage featurs three bays and a large driveway capable of accommodating multiple vehicles. The property is selling mostly furnished with some exceptions (artwork does not convey).
At $929 per square foot, 108 Third Sid stands out for something hard to replicate in Horseshoe Bay: more than half an acre of waterfront land with open water views, a boathouse, and a fully reworked 5 bedroom layout. In Horseshoe Bay, this residential single family residence sits in Horseshoe Bay, TX 78657 in Llano County and pairs a 0.5538 acre lot with 4,252 square feet, 5 full baths, 1 half bath, and a 1985 build that has been remodeled down to the studs.
What is it like to live at 108 Third Sid? The setting is built around the water. The main level opens to broad lake views from the living, dining, and kitchen spaces, with a large stone fireplace creating a clear focal point instead of competing with the view. The kitchen is designed for daily use and large gatherings, with high end appliances, custom cabinetry, a large island, and a walk-in pantry that connects efficiently back toward the garage. The primary suite is on the main floor, which matters for owners who want the main living spaces and bedroom on one level. A library with floor to ceiling bookcases adds a quieter room that can function as an office or reading space.
The lower level shifts the house toward entertaining and guest use. A game room anchors four additional bedrooms, each with its own bath and direct patio access. Three of those bedrooms face the water. Outside, the lake level is set up for actual use, not just views, with a pool, barbecue area, outdoor dining space, and direct access to the boathouse. For buyers considering second home use or short term rental potential, that mix of bedroom count, private baths, outdoor amenities, and waterfront access is the key value driver.
Location matters here. 108 Third Sid is close to the core amenities of Horseshoe Bay Resort, and the property’s position in Horseshoe Bay keeps it tied to the part of the community buyers ask about most. The large driveway and three bay attached garage also solve a common issue for lake properties by giving owners room for guests, water gear, and multiple vehicles. School information is not provided in the listing, so buyers should verify district and campus details directly. With its lot size, remodeled condition, and water-oriented layout, this is the kind of Horseshoe Bay property that holds long-term lifestyle appeal and stays relevant when buyers get more selective.
