Perched atop a hillside in The Summit, a private gated community in Westlake, this stunning modern contemporary home is set into the natural topography and surrounded by lush landscaping, with some of the most breathtaking Hill Country views you’ll find. Custom designed by renowned Miró Rivera Architects, the residence makes a statement from the moment you arrive, with striking edges and a sweeping curved roofline that set it apart from anything else. Step inside and you’re immediately surrounded by natural light. At the heart of the home, the main living room features a dramatic floor-to-ceiling stone fireplace, while sliding glass doors frame sweeping views above the pool. Uniquely shaped and thoughtfully placed windows carry the light through to the kitchen, an entertainer’s dream with a large island, a hidden pantry, and a dedicated appliance room. The formal dining room flows out to the patio, and together with the outdoor pool and patio spaces, it creates a seamless indoor-outdoor connection from the living room to the kitchen to the dining room. The main level is home to the primary suite, which offers gorgeous views and a study at its entry. The spacious primary bath features a double vanity, a separate makeup and getting-ready area, and a large shower that encompasses the spacious soaking tub. A generous walk-in closet with ample natural light and architectural ceilings completes the retreat. Also on the main level are a secondary bedroom with its own bathroom and spectacular views, a powder bath, and a two and half car garage. Upstairs, two additional bedrooms each have their own en-suite bath. The lower level is built for entertaining. It includes a bedroom and full bath, a powder bath, and a stunning wine cellar for your private collection. The large media room features a pool table and an expansive bar area, and opens to another outdoor terrace leading to an expansive yard.  Off the media room is a newly added, sound proofed, flex room used currently as a home theatre and golf simulator, complete with generous storage space. Set on over an acre, the grounds are just as impressive, with both flat usable space and additional land further down the lot, an outdoor putting green, and an outdoor fireplace for cool evenings under the stars. With luxurious living spaces, incredible views, and amenities for every lifestyle, this home truly has something for everyone.
