Experience luxury living at its finest in this gated, single-level custom home, offering over 5,000 square feet of thoughtfully designed space and a rare oversized five-car garage. Located in the prestigious Dunthorpe neighborhood and benefiting from Clackamas County taxes, this residence blends newer, high-quality construction with timeless design, exceptional privacy, and seamless indoor-outdoor living. Situated on two tax lots totaling approximately one acre, the property makes a striking first impression with a circular drive, professionally landscaped grounds, and a spacious motor court—setting the tone for the sophistication found within. Step inside to a soaring great room anchored by a sleek linear gas fireplace wrapped in quartz, setting a modern yet inviting ambiance. The gourmet kitchen is a showpiece, appointed with custom white oak inset cabinetry, a Viking range, dual ovens, dual Sub-Zero refrigerators, a spacious quartz island, and an open-concept pantry. Adjacent to the kitchen, a geothermal-cooled wine cellar provides the ideal space to store and showcase your collection. The primary suite is a serene retreat, complete with a luxurious en-suite bath and an expansive custom walk-in closet. Thoughtfully designed for privacy, the additional bedrooms are well-separated from the primary suite, each featuring en-suite baths and walk-in closets. Two LaCantina folding glass doors open to a covered outdoor living area, outfitted with a built-in BBQ, overhead heaters, and skylights for year-round comfort. A spacious patio offers multiple zones for entertaining, including a fire pit, raised planter beds, and terraced gardens framed by a lush natural backdrop. The oversized five-car garage delivers exceptional storage and flexibility, while whole-house generator ensures uninterrupted peace of mind. Zoned for both Riverdale and Lake Oswego schools, and located just minutes from high-end shopping, dining, and outdoor recreation, this is refined Northwest living.
