Immaculately restored historic treasure - this majestic estate exemplifies Portland's wondrous history at its finest! A National Register of Historic Places residence, the Pierre Rossiter and Charlotte Hines house offers a new roof, gorgeous gourmet kitchen renovation, soaring ceilings and grand rooms including a vast formal living room and elegant dining hall with nearby 4-stop elevator. The picturesque terraces are lined with classic balustrades overlooking the Lord & Schryver designed 1.86 acre grounds. Once a horse property and still offering all the beauty of Dunthorpe's celebrated 'Riviera' estates that lined the Willamette River, this prime example of luxuriously classic modern living offers 4 floors of versatile living space. Enjoy a richly milled library with wet bar, plush family room, stunning foyer, and regal main staircase. Upstairs you'll find a palatial primary suite with enormous custom dressing room and remodeled marble spa bathroom with clawfoot tub. 4 additional bedrooms and 3 bathrooms nearby - so many options for family and guest accommodations! The third floor is finished as a media room with nearby full bathroom and elevator access. The lower level offers a temperature controlled wine cellar, incredible recreation/flex space, and extensive laundry facilities. Revel in the basketball court, amazing vaulted 254 sf heated playhouse, veggie gardens, blueberry bushes, and a detached 3rd garage. Surrounded by privacy hedges, the estate is its own "Secret Garden" in the heart of it all. The convenience of two access gates, proximity to both vibrant Lake Oswego and Portland amenities plus Oregon's top-rated Riverdale Schools complete this incredible offering.
