Rising above the tree line, the Blue Lake Retreat is a modern treehouse in Marble Falls, Texas. The three-story metal structure ascends vertically to accomodate its steep plot. Designed to create unspoiled views of the surrounding landscapes, the main living space sits beyond the trees in the home’s top floor and is framed by a glass north facing wall. A cantilevered deck extends toward the water, taking full advantage of the lakeside setting. Backed by the privacy of the adjacent hillside, all four bedrooms are split between the lower two levels and feature their own balconies with unique views of the neighboring shore.
