A unique, sustainably designed residential property in Tenino, Washington, has been listed for $11 million, positioning it as one of the most expensive homes in the South Puget Sound region. The 85-acre estate, which includes a main residence described as "Guggenheim Museum meets spaceship" and a separate 3,000-square-foot guesthouse, offers a near off-grid lifestyle approximately 90 minutes from downtown Seattle. Listing agent Michael Morrison emphasizes the property's sense of peacefulness and its appeal to buyers seeking a minimalist, sustainable retreat with proximity to a major city.
The main house's design is a study in modern, minimalist architecture. It features flowing, serene walls without traditional baseboards, floor trim, or door trim. The design prioritizes soft, rounded shapes, with multilevel landscaping inspired by Scotland's Garden of Cosmic Speculation. Each room has a dedicated color scheme, and custom furniture is designed to complement the curving walls. This approach creates a cohesive and visually striking living environment that stands apart from conventional home designs in the Pacific Northwest.
Sustainability was a core principle in the property's development. The walls are constructed from American ionized clay, and the energy system utilizes gel batteries for electricity storage. Heating is provided by geothermal water heaters and a solar-powered boiler. According to the listing agent, the current owner received an electric bill for only $21, demonstrating the home's remarkable energy efficiency. Additional features include a propane-powered fireplace and fiber-optic lighting in the bedrooms, further reducing reliance on public utilities.
The estate functions as a self-contained private retreat. Outdoor amenities include an 80-foot rectangular saltwater pool with retractable glass walls, an oval water feature, a triangular reflecting pool, and an archery range. The grounds feature tiered gardens, a greenhouse, and fruit trees producing plums, kiwis, pears, and apples. A chicken coop and corral are also present. For future expansion, the property has space for adding equestrian facilities or a helipad. The included three-bedroom guesthouse provides ample space for visitors.
Based on our experience assessment, the ideal buyer is likely a high-net-worth individual seeking a primary residence or vacation home that offers seclusion without complete isolation. The property's location provides a 90-minute drive to Seattle's urban core, making it suitable for someone who desires access to city amenities but prefers a daily life defined by tranquility and natural surroundings. The architectural significance and advanced sustainable systems will appeal to buyers with a passion for design and eco-conscious living.
The $11 million asking price reflects the property's unique architecture, extensive acreage, and high-end sustainable features. For a buyer valuing privacy, modern design, and a near off-grid capability, this Washington estate represents a rare opportunity. The potential to add equestrian or aviation facilities adds significant value for those with specific lifestyle needs.
