Rarely does Sammamish offer a fully renovated main residence & a custom-built 2024 Guest House (DADU) with attached fitness studio on a private 1.21-acre estate surrounded by mature trees and natural beauty. Together, the two residences provide nearly 4,300 sq ft of flexible living space, creating exceptional opportunities for multi-generational living, long-term guests, a private office, rental income, or a personal retreat. Nestled among lush Northwest greenery, the property offers a rare sense of tranquility & privacy while remaining convenient to amenities. The fully renovated 3,310 sq ft main residence features light-filled living spaces, seamless indoor-outdoor flow, premium finishes, a dedicated home office, spacious recr room with wet bar, and a luxurious Primary Suite with an oversized walk-in closet & spa-inspired five-piece bath. The detached Guest House is a standout feature, offering two bedrooms, soaring vaulted ceilings, private porch access, & a dramatic wall of glass that opens to the surrounding landscape. Thoughtfully designed for flexibility & independence, it provides space for guests, extended living, work-from-home needs, or income-producing potential. Outside, over $150,000 in landscaping improvements transform the grounds into a private retreat complete with an athletic court, outdoor sauna, wraparound deck, & multiple outdoor gathering spaces. A new roof and whole-house generator add lasting value and peace of mind. A distinctive estate property!
