Description
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 has newer concrete that spans the whole rear and side of the home. Also included in the 2022 remodel is fresh hardscape with seating and tiered planters with steps to the sloping hillside, ready for your gardening touch. The primary bedroom, bathroom, and one bedroom were reimagined in 2020 to create a dream retreat. The primary bathroom has custom tile throughout with a large walk-in shower with glass doors. There is a lovely skylight for ambient lighting and a massive walk-in and walk-through closet with a custom storage system. There are three other spacious bedrooms and a bright hall bathroom as well. Enjoy the newer dual-pane vinyl windows (2020) and relax in the climate-controlled environment thanks to the 2022 HVAC system. Tesla solar system installed in 2014 on the 2022 roof! More than just a property, this home has been lovingly cared for and updated - ready for you to enjoy!
