xTucked beneath a canopy of majestic oaks in the heart of Old Lakeway, this extraordinary custom residence feels more like a private boutique retreat than a traditional home—elegant but not dated, artistic yet approachable. Its owners value character, artistry, hospitality, and creating experiences. They host dinner parties that linger late into the evening, travel often, collect stories and treasures, and want a home that reflects who they are. Designed for effortless indoor-outdoor living, the home welcomes you with expansive covered verandas, multiple sets of French doors, and beautifully landscaped courtyards that invite gathering, entertaining, or quiet moments. The firepit courtyard creates a magical setting for evenings under the stars, while gardens surrounding the hot tub provide beauty and privacy. Inside, sophisticated design blends seamlessly with warmth and character. The chef's kitchen serves as the heart of the home, featuring custom cabinetry, dramatic stone countertops, a hammered copper farmhouse sink, oversized island, and premium GE Café appliances. Adjacent living spaces are filled with natural light and anchored by a striking fireplace. A spacious guest suite and bath complete the main level, while the full-length front porch, framed by three sets of French doors, embraces the home's distinctive New Orleans Low Country architecture. Upstairs, the primary suite offers a sanctuary with treetop balcony access, a spa-inspired bath, and an impressive library/office with extensive custom built-ins. A second guest suite features its own balcony and ensuite bath. Above the detached garage, separate guest quarters with a full bath and kitchenette offer flexibility—ideal for visitors, a private studio or workspace, multigenerational living, or income-producing potential. Located minutes from Lake Travis, golf, marinas, parks, acclaimed schools, and everything that makes Old Lakeway special, this isn't just another Lakeway listing. It's a lifestyle.
