Property Description
Offered for the first time since its custom construction by Parkison Construction, this extraordinary Columbia River estate is a true legacy property. Boasting over 175' of river frontage and breathtaking 180° views, the home overlooks passing ships, bald eagles, deer, and an ever-changing waterfront landscape. On clear days, enjoy views toward Astoria, fresh ocean air, and Long Beach just 20 minutes away. Located within a unique Pacific Northwest rain shadow, the property enjoys less rainfall and more sunshine than neighboring coastal communities. Expansive wind-rated windows frame the river from all south-facing rooms while providing exceptional insulation. The interior features hand-textured ceilings, an acid-washed Italian marble fireplace, Anne Sacks designer tile, custom Thomasville cabinetry in Milk Wash Marine, stainless steel appliances, and a downdraft island cooktop. Built for efficiency and longevity, the home includes a DC heat pump, hybrid water heater, whole-property generator servicing both the main residence and ADU, Ram Jack foundation system with a 75-year home warranty, reinforced retaining wall, fire-rated expansion joint, private well with dual pumps, approximately 5,000 gallons of water storage, and extensive irrigation. The primary suite captures spectacular river views, while an ADA-accessible ramp and extra-deep 2-car garage enhance accessibility. A 600 sq ft ADU with 1 bedroom, 1 bath, and direct access to the 2-car shop is ideal for guests, multigenerational living, caretakers, or rental income. Additional improvements include a 38' RV storage building, and full RV hookups with power, water, and sewer. Outside, over 200 mature Laurel hedges provide exceptional privacy, surrounding an award-winning English rose garden, walking paths, a pond with electrical service, wetlands, mature landscaping, a garden shed, dog run/catio, and panoramic views of Mount St. Helens and Mt. Adams.
