Rare 1 acre property featuring a fully updated, taken-to-the-studs, ~$523K remodel on a 1 story home plus an exceptional 900 sqft insulated workshop which includes a 200 sqft office space.

More improvements include new dimensional roof, blown-in attic insulation, LED lighting throughout, fireplace rebuild, full laundry/utility room addition, new 4th bedroom, privacy fencing, new driveway, sidewalks, + extensive landscape upgrades. The 30’x30’ workshop is a major highlight with insulated walls/roof (closed-cell spray foam), (2) 16’ electric lift insulated doors, 40” soaker sink with water heater, temperature-controlled exhaust system, separate 200-amp service, 30-amp generator plug, dedicated appliance circuits, interior/exterior 220V plugs, conditioned 20’x10’ office with storage, reclaimed-wood exterior accents, and LED interior/exterior lighting. A covered trailer/storage bay with gate access adds even more utility. All with a backyard paradise that backs into the creek.
