Overview

Property Description

Welcome to The Epic Peninsula House. Perched high above the shimmering expanse of Lake Travis, The Epic Peninsula House is a modern architectural tour de force, envisioned by renowned Telluride architect Tommy Hein. Located on a premier 2.6-acre estate within the prestigious Peninsula at Rough Hollow, the home unites cutting-edge design with a reverence for the natural landscape. Currently under construction, Epic Peninsula is a retreat shaped by the land and water that surround it. Perched above the tranquil shores of Lake Travis, this home embraces the natural contours, with living spaces that floats above the bluff, offering uninterrupted views. An L-shaped pool wraps around a sunken lounge, blending indoor and outdoor living in a seamless embrace. Carefully created by the developer for its rare combination of panoramic main-body lake views and protected cove access, this lot is among the most coveted in the community. It offers the best of both worlds: sweeping vistas and the serenity of a sheltered two-slip private dock, perfect for swimming, boating, and lakeside leisure. “From the start, we knew we wanted to honor the views and create a modern home using materials authentic to the environment,” shares the homeowner. “Tommy immediately aligned with that vision.” Hein, celebrated for crafting homes that seem to emerge from the land itself, embraced the site’s unique topography to inspire the structure’s form. The result is Epic Peninsula, Crafted from natural stone, Texas brick, warm wood, and metal accents, Epic Peninsula is anchored by a central stone form that rises from the earth, a tribute to the landscape that inspired it. This is architecture that lives and breathes with its surroundings. Inside, floor-to-ceiling glass walls frame unobstructed lake and Hill Country views while saturating the interiors with natural light. Expansive terraces dissolve the boundaries between indoor and outdoor living, inviting the landscape into every room.
