A romantic rose-adorned country villa sited on nearly an acre fronting the original Edgecliff loop created when Dunthorpe was a newly established neighborhood. Designed in 1935 by Harry Borland for Mrs. William Zimmerman, the residence was dubbed the "Mahogany House" for its exquisite millwork. Offering complete privacy and solitude, this magical residence surrounded by extensive gardens enjoys views of both Mt. Hood and the Willamette River.Decades ago the current owners engaged renowned Landscape Architect Craig Kiest to design grounds with a circular driveway, lush gardens & patio for the heated in-ground pool. Enter the mahogany front door into a central foyer with dramatic curved wrought iron staircase. An archway leads to the formal living room that easily accommodates a grand piano and is appointed with red oak floors, a gas fireplace and lead glass casement windows. Step through French doors to sun and dining rooms where Mt Hood is front and center. Classic black & white carrara marble kitchen and breakfast room view east through rose bedecked windows. The family room off the kitchen features a fireplace & plaster brocade ceiling.The upper floor consists of 3 bedroom suites with carrara baths and includes a primary wing.Lower level family room with a third fireplace & an entire wall of bookcases; ideal for a billiard or ping pong table.Additionally there are 2 exercise rooms & a half bath. Across the breezeway from the main house & above the 3 car garage are guest quarters.This airy space has a kitchen, full bath, cork floors & mini split for heating & cooling.Formerly an art studio, it is flooded with natural light. A country feel, yet minutes to downtown Portland & Lake Oswego.A few minutes walk to Riverdale Elementary School which serves as the center of the community with its park & playground.Near OHSU, Lewis & Clark College & Tryon Creek Park, the location feels worlds away with its sleepy solitude, birdsong & leafy lanes.Enjoy Clackamas County taxes.
