A Main Lake Masterpiece – Fully Reimagined Mid-Century Modern. Set on one of Oswego Lake’s most coveted waterfronts with panoramic main lake views, this elevated Diamond Head Peninsula home has been completely transformed by one of Lake Oswego’s most sought-after designers — honoring its mid-century roots while reimagining it into a fresh, timeless, move-in-ready showcase that feels like new construction. Just behind historic Jantzen Island, your private dock offers direct access to one of the lake’s most beloved gathering and swim spots, pairing vibrant summer energy with peaceful year-round views. Walls of glass, vaulted ceilings, and clean lines frame sunsets over the water, while natural textures, warm wood tones, and soft neutrals create an inviting, light-filled interior. The gourmet kitchen centers around a large quartz island and all-new Wolf, Sub-Zero, and Cove appliances. The spa-inspired primary suite features heated floors, a steam shower, and custom walk-in closet. Multiple guest suites, flexible living areas, and expansive decks encourage seamless indoor/outdoor living. Wellness amenities include an infrared sauna, while the dock’s two levels of lounging decks and boat lift make every day a vacation. All this, just minutes from downtown Lake Oswego’s shops, dining, and farmers market. Iconic location. Timeless design. Ready now.
