Property Description

A rare and architecturally significant offering, this transitional modern estate was designed by acclaimed Oregon architect Richard Marlitt, and rests gracefully on over two dynamic level acres of private, meticulously curated grounds. Celebrated for his mastery of proportion, light, and spatial harmony, Marlitt’s intelligent proportions and Mid Century design create a seamless dialogue between indoors and out, where walls of glass, soaring ceilings, generous room sizes and thoughtfully placed French doors invite nature into everyday living.Extensive renovations have transformed the home into a beautifully modern residence while remaining true to its original architectural vision. Defined by its effortless main-level living, elegance and fluid floor plan, the home offers both grand entertaining spaces and intimate retreats. Outdoors, the estate transforms into a resort-like setting with exquisite grounds, a sunlit pool terrace, and a seemingly endless and expansive lawn. Enjoy a fully equipped pool house—featuring its own living quarters, kitchenette, and fireplace—ideal for guests or extended entertaining. Mature trees, curated gardens, and seasonal blooms create a landscape of year-round beauty, enhanced by extensive lighting that brings the grounds to life after dusk.With a legacy of thoughtful stewardship and extensive modern updates, this is a timeless residence where architectural pedigree meets contemporary comfort—offering a rare opportunity to own a truly distinguished and elegant Oregon estate.Characterized by grand residences set on generous acreage, mature landscapes, and quiet, tree-lined lanes, the welcoming Dunthorpe neighborhood offers a rare blend of privacy, prestige, and community—an enduring legacy that has made it one of the Pacific Northwest's most coveted residential enclaves.
