The finest in floating home living, welcome to this stunning contemporary cabin at McCuddy’s Big Oak Marina. Built just 15 years ago by renowned river builder Rick Christiansen, this home features exceptional craftsmanship and a 4-rated float with steel stringers, making it fully financeable and built for long-term value. Positioned on one of the most beautiful stretches of the Multnomah Channel, the home is designed to capture the river with expansive walls of windows on both levels. The upper-level great room showcases a vaulted tongue-and-groove ceiling with a full-height window wall to the peak, creating a bright, open living space with incredible views of river, mountain and PNW wildlife. The layout offers two bedrooms and two bathrooms, with one of each on both levels. Hardwood flooring runs through the main level and upper great room, complemented by tile in the primary bath and carpet in the primary bedroom. Outdoor living is equally impressive, with a wraparound upper deck on the river side, another private upper deck off the primary bedroom on the bank side (perfect for relaxing and catching wildlife right outside your bedroom door) and rooftop deck offering some of the best views in the moorage, ideal for entertaining or relaxing while taking in the peaceful river lifestyle. The home is finished with beautiful natural cedar siding and hardwood decking, all of which have been meticulously maintained. Lightly lived in as a second home, the property has been exceptionally well cared for and has never had shoes worn inside. Located in the well-regarded McCuddy’s Marina family who own over 7 other marinas in the greater Portland area and benefiting from some of the lowest slip rent in the area by far, this is a rare opportunity to own a custom-built floating home, offered for the first time by the original owners. Experience floating home living at its best today!
