Welcome to this beautifully updated Gaithersburg home, ideally located near Seneca Creek State Park and Clopper Lake, Rio, and Downtown Crown, with convenient access to shopping, dining, recreation, and major commuter routes. Extensive improvements completed in 2019 include replacement of the plumbing, electrical updates, a new HVAC system, driveway, roof with new plywood and shingles, and exterior walls upgraded with new plywood, siding, and trim. All bathrooms were fully renovated in 2019. Gas line was installed in 2019 that connects water heater, stove and back yard grill. The outdoor spaces are designed for everyday enjoyment, featuring backyard stonework and a porch completed in 2019. A storage structure was added in 2022, along with artificial turf and fencing. The basement offers additional possibilities, with rough ins behind the wall for a future wet bar and laundry area. The water heater will be replaced. A move-in-ready home with significant updates in a prime Gaithersburg location!
