Description
Available only for the third time in its history is this breathtaking 24-acre Hill Country estate overlooking Canyon Lake at The Peninsula at Mystic Shores. Originally the headquarters of the 711 Ranch established in 1949, 300 Saga Street is a magnificent property comprised of a Roger Rasbach-designed six-bedroom, six full bath and two half bath main house, swimming pool and pool house, a two-bedroom, two bath guest house, studio, outdoor cabana and four car garage with apartment. Exceptionally maintained and sitting under a canopy of hundreds of majestic oak trees, the property is perched over the lake and boasts over 1500 feet of unobscured views of the water and surrounding Hill Country. The main house is a beautifully preserved Mid-Century masterpiece with clean lines, floor-to-ceiling windows, open floor plan, impressive wood paneling and accents and original Terrazzo flooring. Off the stunning entry is the grand, formal living room with massive fireplace that overlooks the grounds and lakefront. Adjacent on one side is the formal dining room with its rich bank of built-ins, and on the other side is a spacious den with full wet bar with a wall of windows that frame the lush hill country landscape. Across from these formal living and dining spaces, you'll find a large breakfast room, butler's pantry, and full kitchen with large walk-in pantry and private prep/staging area. The large primary suite is secluded off the living side of the estate with his- and her- baths. The remaining ample-sized bedrooms are located on the opposite wing of the house. Out back, there's a large, covered patio that overlooks the lake, grounds and sparkling pool. The pool house sits just to the side of the main house, and has a comfortable living area, wet bar and his and her changing rooms. There's a four-car garage opposite the house, with an apartment attached. Just down from it, you'll find the two-bedroom, two bath guest house with living, dining, kitchen and sitting areas, as well as a screened-in porch. This amazing property also features a studio, outdoor cabana and grilling area and additional carport and outdoor storage building. There literally is so much to behold, and the possibilities for its present and future - with its premier waterfront location, existing footprint and available land - are endless. This property is agent open. Please provide 12-24 hours advance notice.
