From the moment you step into the foyer at 23521 Flat Creek Drive in Marble Falls, Lake Travis spreads before you in unobstructed panoramic views that define life on this 1.95-acre waterfront peninsula in Marble Falls. This four-bedroom, three-and-a-half bath residence sits 3,644 square feet of thoughtfully oriented living space designed entirely around capturing the water and Hill Country landscape. The home's architecture places you above the shoreline, not beside it, so every major living area opens toward the vista rather than the street.
The window strategy is where this property reveals its purpose. Cathedral ceilings rise throughout the main living level, drawing your eye upward and outward through walls of glass that frame the glittering water. The great room anchors this view with a limestone fireplace featuring fossilized details, positioned so you can sit by the fire while watching the lake. The pastel green granite kitchen sits open to this sightline, with an island and eat-in area that keeps the water in view during every meal. High-speed internet runs throughout, making the study and home office equally useful for work with a view.
The deck system extends your living into the landscape. A wall of glass opens from the great room to both covered and open decks that jut toward the water. Two additional decks overlook the tennis court on the upper portion of the property, creating outdoor living options throughout the day. The primary suite occupies the main level with its own windows framing the lake. An in-law suite sits five steps up, offering independence while maintaining connection to the main home. The upper level guest quarters includes a den or game room with a second fireplace, bedroom, full bath, and another deck capturing the vista.
This is living above the water, not on it. The private boat dock and ramp give you launch access without the permanence of traditional dock living. You're one mile from Flat Creek Estates winery and vineyard with its bistro and disc golf. The Marble Falls neighborhood sits on a private maintained road, adding seclusion. Marble Falls Independent School District serves the property, with Colt Elementary, Marble Falls Middle, and Marble Falls High as your district schools. At $372 per square foot, this waterfront home with Lake Travis panoramas positions you in a market where view properties command premium rates.
