Where timeless architecture meets the tranquility of Lake Austin—welcome to The Venetian, a waterfront estate that evokes the grace and romance of the Italian Renaissance. Designed by Impact Design and masterfully built by Keith Schoenfelt of Corias Homes, this 7,755-square-foot residence sits on over half an acre with more than 180 feet of Lake Austin frontage, offering two boat slips—one private and one for guests. The home’s craftsmanship and scale are rare to find today, blending elegant proportion with enduring structure. From the moment you enter, you’re surrounded by exquisite detailing: soaring ceilings, intricate millwork, and walls of windows that fill the home with natural light. Formal and casual living spaces flow seamlessly, each designed with a sense of poetic rhythm and refined character. Whether you’re hosting on a grand scale or enjoying quiet moments on the lakefront terrace, every space invites connection and contemplation. Outdoors, the grounds feel like a living painting—lush, terraced gardens inspired by Italian tradition, perfect for al fresco dining, slow strolls, or simply watching the sun dance on the water. With five generously appointed bedrooms, a stately office, and multiple living and dining areas, the home accommodates both everyday life and exceptional entertaining with ease. Its thoughtful layout and authentic preservation of character make it a true work of art—a lakefront legacy in the making.
