Remarks

This private Diamond Bar Ranch-style residence is situated on a large private lot in a cul-de-sac neighborhood. Gracious double-door entry to a large foyer leading to the step-down living room with a charming fireplace. The kitchen is a gorgeous 2021 remodel. Quartz countertops, tile backsplash, and recessed lighting wth an under-mount sink. Totally custom cabinetry, including a handy "lazy susan" corner cabinet. The culinary island includes ample seating, storage, a six-burner Thermador range, and an exhaust hood. Built-in Kitchen Aid double ovens with a top-of-the-line refrigerator, Thermador dishwasher, PLUS drawer-style microwave complete the appliance package. The center island offers ample storage for those small appliances and decor that are not often used. Speaking of storage, do not overlook the walk-in pantry installed in 2010 with custom shelving! The kitchen sewer line was sleeved in 2019. Direct access to the kitchen is from the two-car garage. You'll find the laundry, the water softener (paid for in 2020), and the oversized water heater (2022). Off the glamorous kitchen is a large dining area which opens to the family room for ease of entertaining. The family room has beamed vaulted ceilings and sliding doors to the covered patio. Remodeled in 2022, this patio space
