## Description

### Agent Description
A one-of-a-kind opportunity to own one of Idaho's most iconic legacy estates. Privately positioned behind the gates of an exclusive waterfront enclave, this extraordinary 17.5-acre property offers over 1,200 feet of Boise River frontage, more than 2,400 feet of private lake frontage, and unmatched privacy bordered by protected state land. Encompassing nearly 12,000 sq ft with 6,000+ sq ft of covered outdoor living and 4,200+ sq ft of garage space, the residence was designed for year-round entertaining and resort-style living. Extensive renovations completed between 2024-2026 introduced designer finishes, custom stonework, and dramatic walls of glass with water views from every room. Amenities include a full indoor regulation basketball court with viewing lounge, professional-grade pickleball court, remodeled upstairs lounge and poker room with second kitchen and statement wine room, state-of-the-art theater with seating for 12, and a wellness retreat featuring a commercial-grade gym with $70k+ in Rogue equipment and sauna. Outdoor living is unparalleled with a heated pool and spa, waterfall-edge features, private lakes, sandy beachfront, new dock, outdoor kitchen with Wolf grill and Traeger smoker, fire features, pergola lounges, fountains, and curated entertaining spaces throughout. An extraordinary blend of luxury, recreation, privacy, and natural beauty.
