A rare opportunity to own an extraordinary Pacific Northwest retreat! Set on nearly 20 acres in this peaceful yet convenient Rainier-area setting, this custom-built home combines quality craftsmanship, thoughtful design, and a ready-to-go equestrian setup. Soaring vaulted ceilings anchor the inviting great room, while the chef's kitchen, luxurious primary bath, and dedicated home office reflect the attention to detail throughout. Split floor plan, with no detail left out. Wood-clad ceilings on the covered front and back porches add warmth and character, creating inviting spaces to enjoy the surrounding landscape year-round. Watch elk and deer wander past your living room, or saddle up and ride right at home with an outdoor arena, established fencing, trail system throughout the property, and plenty of room to roam. The exceptional value extends beyond the home itself: a separate 7-acre parcel, already addressed with a preliminary site plan filed with the county, offers exciting potential for a second homesite or the opportunity to sell the additional acreage. Enjoy the freedom, privacy, and possibilities of a truly special property, with room for your horses, hobbies, and future plans.
