Coveted location in the North Shore neighborhood of Lake Oswego! This stunning one-level, mid-century modern home is the work of design innovator Pietro Belluschi's understudy Marjorie Wintermute and has been brought up to contemporary standards while maintaining its original designer charm. Tucked away in a private setting, yet walkable to downtown Lake Oswego, the Lake Oswego Country Club, and more, this 3 bedroom (potential 4 or office), 4 bath home is an oasis in the city! With a heated enclosed patio including an outdoor living and dining area and kitchen, built-in Memphis grill, a gas-ignited Timberline-styled wood fireplace, all overlooking the heated pool and rock waterfall, this home lives large inviting the outdoors in year-round. Walls of double-paned Anderson windows and sliding doors throughout bring in tons of natural light and provide a beautiful view of the pool and garden. Multiple skylights looking up into the trees add to the tranquil setting. Vaulted ceilings in the kitchen, living, and dining rooms provide wonderful architectural accents. The kitchen itself features underfloor heating and beautiful walnut MCM cabinetry. Hardwood floors are found throughout. Above the garage, find a rare ADU with a separate entrance, bathroom, and kitchenette. A pool room adjacent to the patio can be used as a sleep out, studio for art, exercise room, or office. Additional features include an EV charger in the garage, a home security system, a hookup for a generator in the outdoor living area, as well as a 450-bottle temperature-controlled wine closet, a Rainbird irrigation system with 3 stations covering all the garden areas, an electric pool cleaner, outdoor lighting, a double garage with shelving, storage units, and workshop, and more! A woodland garden provides a low-maintenance retreat to the rear of the house. Deeded rights to three lake easements make this the perfect place to enjoy Lake Oswego living at its finest!
