Listing information updated 7/17/2026 at 3:41pm
This truly unique property has been extensively remodeled and is one of a kind! It features 6BR/4BA (including an attached 1BR/1BA inlaw/au pair suite with full kitchen and separate entrance), a 4-5 car garage with high-bay, solar power, and iconic lighthouse replica outbuilding. The house has hardwood floors throughout, crown molding and wainscoting in the living room; granite countertops, maple cabinetry, stainless steel appliances, ceramic tile flooring, and travertine tile backsplashes with motifs and accents in the Tuscan-inspired, remodeled eat-in gourmet kitchen. A spacious fully-finished family/rec room in the walk-out basement leads to an adjoining Trex deck. An en suite bedroom, oversize finished laundry/sewing/crafting room, mudroom, and generous storage space complete the lower level. A 23' x 11' Bonus Room with hardwood floors, crown molding, brick accent wall, and separate entrance on the main level can serve as a formal dining room or a home office. An oversize 24' x 32' attached 2-car garage plus 16' x 40' high-bay built for an automotive lift. Additional 11' x 29' workshop is actually another 1-1/2 car garage that is partially closed off, but can be restored to allow a 5th vehicle to be garaged. The High-Bay and Workshop are heated with propane, enabling year-round usage. Two driveways provide additional paved off-street parking. The detached Greenfield Lighthouse was built in 2015. Its design was inspired by Oregon's Yaquina Bay lighthouse and provides a peaceful retreat, studio, office, homeschooling classroom, playhouse, or more storage space on 2 main levels. A drop-down staircase provides access to a 3rd level, and the 4th level light room provides a view of the neighborhood and beyond. The entire lighthouse and the inlaw/au pair suite are entirely powered by solar, which also supplies electricity to the remainder of the property. With its separate entrance and full kitchen, the inlaw/au pair suite could be licensed as a Class 3 Auxiliary Dwelling Unit (ADU) (buyer to confirm necessary rules/codes). The solar panels convey and generate an average of 12,000 kWh annually--more than 95% of the property's electrical usage (records available for inspection). Located in the Meadowbrook Estates subdivision, a quiet neighborhood with no thru streets, but convenient access to public transportation, shopping, and I-270.
