Welcome home to this beautifully updated 4-bedroom, 3-bath residence in the sought-after King Ranch Estates neighborhood of Thornton. Thoughtful upgrades throughout blend comfort, style, and energy efficiency. Enjoy relaxing mornings on the covered front porch or evenings on the backyard deck overlooking the landscaped yard with mature plants and a storage shed.
Step inside to find new carpet throughout, luxury vinyl plank on the main level, and an open-concept layout filled with natural light. The kitchen features stainless-steel appliances, granite counters, a center island, pantry, and eat-in dining area—perfect for gatherings. Just off the kitchen is a convenient built-in desk/work nook connecting to the 3-car garage. The family room’s gas fireplace adds a cozy touch on cool Colorado nights.
Upstairs, the spacious primary suite offers a quartzite-finished 5-piece bath and an expanded closet with custom organizers. Three additional bedrooms and a full bath complete the upper level, while the garden-level basement provides room to expand, with great light for a future gym or media space. Recent updates include a new roof and screens (1 year), exterior paint (2021), high-efficiency furnace, and paid solar system for lower energy bills.
Located near scenic King Ranch Park, Platte Trail, and Riverdale Regional Park, and just 30 minutes to downtown Denver or the airport. Includes a Zillow 3D Tour for a closer look!
