House Description

Sisterdale Farms is one of those rare Hill Country places where history and modern comfort come together across 310 acres of real Texas beauty. At its center is a stunning stone home inspired by early German settlers-11,800 square feet filled with character, from hand-carved limestone mantels to seven Rumford fireplaces, and a kitchen that features a wood-fired pizza oven with a quote stenciled on its mantel from Olmsted's Journey Through Texas. Every window in every room frames a different, breathtaking Hill Country view-rolling hills, ponds, gentle fountains, and a beautifully tended organic garden that brings color and life to the grounds. Charming courtyards and gorgeous landscaping create inviting outdoor spaces, while comfortable guest quarters with sweeping views and a deep pool with shaded terraces overlook the Guadalupe River Valley. With productive hay fields, river frontage, and a rich legacy that dates back to Texas' first librarian, this property offers a unique blend of heritage, luxury, and working farm and ranch life. This one-of-a-kind farm carries a legacy woven through generations. It's a place where history, craftsmanship, and land come together-inviting you not just to own a property, but to become part of an ongoing story. Whether you're captivated by its past, the artistry of its buildings, or the beauty of the land, Sisterdale Farms offers something rare: a chance to step into a living heritage and make it your own. At the heart of Sisterdale Farms stands the main residence-a masterfully crafted, 11,800-square-foot stone sanctuary designed and built by acclaimed architect Don McDonald, who intentionally positioned the home to capture views of the Guadalupe Valley, along with spectacular sunrises and sunsets. Inside, the home unfolds with elegant yet understated grace and generous scale. Five bedrooms with ensuite baths offer privacy and comfort, while three additional half baths serve guests and poolside visitors alike. The interior is enriched by two octagonal libraries filled with light and quiet, a formal sitting room for intimate gatherings, a spacious living room, and a dedicated gym for wellness and fitness. Upstairs, two wings expand the living space with a private media room, study areas, and a distinctive tower that provides 360-degree panoramic views of the surrounding Hill Country. The kitchen serves as the home's true heart-spacious and designed for both everyday living and large-scale entertaining. Custom cabinetry, expansive countertops, and state-of-the-art appliances are complemented by a wood-fired pizza oven built into a custom Rumford fireplace. Beyond the main house, the estate's footprint expands to include separate guest quarters-a freestanding residence featuring its own office with sweeping panoramic views, a kitchenette, two full bathrooms, and Murphy beds thoughtfully incorporated throughout, offering flexibility for family or visitors. Looking down toward the river, the historic German homestead stands as a living tribute to the past. This approximately 2,000-square-foot, two-bedroom, two-bath home, originally built in the 1870s, has been thoughtfully restored by Don McDonald. With newly built kitchens and baths, preserved original paint and wood finishes, and authentic Jahn-period furnishings, it offers a seamless blend of history and modern convenience. Adjacent to the homestead is the charming "Cowboy House," a relaxed, rustic guest residence ideal for overflow visitors or staff accommodations. Outside, the artistry of stone continues throughout the landscape, with detailed native Sisterdale limestone forming patios, courtyards, and fire pits that create intimate outdoor living spaces. A stunning 38-foot pool with a deep 12-foot end and adjoining hot tub invites year-round enjoyment, all while overlooking the sweeping valley below. Multiple shaded porches and seating areas throughout the grounds provide places to gather, reflect, and savor the beauty of Sisterdale Farms.
