This is your chance to own a true mid-century modern architectural gem. Built in the 1960s by notable Portland developer Robert Rummer, this 3-bed, 2-bath post-and-beam home retains its original open-air atrium - a rare and sought-after Rummer feature. Watch the rain fall through the middle of your home in winter, or sunlight pour in come summer. A home that seamlessly blends indoor and outdoor living, with exposed post-and-beam construction, tongue-and-groove ceilings, skylights, and an atrium at its center. A formal dining room sits just off the atrium on one side, with a large living room on the other - the atrium anchoring the home's central flow. The home offers 2,263 sq ft of living space, surrounded by established, low-maintenance landscaping and year-round greenery. Meticulously maintained polished concrete floors have working radiant heat, plus two ductless heat pumps for summer cooling. Skylights throughout, and a cozy gas fireplace set beneath original brick chimney. Kitchen updated with walnut cabinetry, quartz countertops, and new Thermador appliances. The enlarged primary bedroom features a freestanding soaking tub and a walk-in closet. The second bathroom retains a sunken Roman bathtub, a distinctive original Rummer feature. Backyard art studio shed and additional storage room adjacent to the main house. Parking includes both a carport and a 1-car garage. New 2025 roof by Raindrop Roofing with a 10-year transferable warranty. An installed Tesla EV charger adds modern convenience, and the home's location in unincorporated Washington County means lower property taxes than comparable Portland homes. Located in Garden Home, one of the most sought-after Rummer neighborhoods, near the Fanno Creek Trailhead, Trader Joe's, and Multnomah Village, with a short drive to Nike World Headquarters and downtown Portland. A well-preserved piece of Portland's mid-century architectural history.Home inspection & sewer scope completed & avail upon request!
