More Room to Live — 4 Bedrooms in a Neighborhood Where Most Have 3. Whether you’re discovering this pocket of Thornton for the first time or you already love the area and need more space, this updated 4-bedroom home offers something rare around here: real square footage. At 1,704 square feet on a 7,680 sqft lot, the floor plan gives you room to spread out — most homes on the surrounding streets top out around 1,100–1,200 square feet with only three bedrooms. The remodeled kitchen anchors the main level with new cabinetry, solid-surface countertops, stainless steel appliances, and a center island with built-in cooktop and overhead vent hood — built for everyday cooking and weekend hosting. Tile flooring and a contemporary backsplash finish the space. Beyond the kitchen, the main living area opens up with updated flooring, recessed lighting, and large windows that pull in natural daylight. Three bedrooms sit on the main level for easy single-floor living, with a fourth bedroom upstairs — perfect as a guest room, home office, or flex space for a growing household. Brick-and-frame construction, forced-air heating, full and three-quarter baths, attached one-car garage, and a fully fenced yard. Adams 12 Five Star Schools, minutes to I-25, Thornton Town Center, and nearby parks. Downtown Denver is a quick commute; shopping, dining, and recreation are right around the corner — the kind of established neighborhood that newcomers gravitate toward and longtime residents rarely leave. If you’ve outgrown a smaller home a few blocks away, or you’ve been searching this zip code from the outside looking in, here’s your chance to step up in size — and bedroom count — without compromising on location.
