One-Bedroom ADU

This 993-square-foot accessory dwelling unit in Johnstown, Colorado was designed for a single owner-occupant or rental tenant seeking a compact, efficient home with room to grow. The main floor delivers a complete one-bedroom layout with a full bath, laundry, kitchen, and a living area that opens to the outdoors. Above, an open loft adds flexible bonus space suited for a home office, studio, or overflow sleeping area. The stepped roofline and dormer give the structure a distinctive presence while keeping the massing in scale with surrounding neighborhood homes. Horizontal lap siding in a neutral tone, black window trim, and a dark shingle roof give it a clean, contemporary character without calling undue attention to itself. For infill sites and backyard lots throughout Weld County, this plan demonstrates how thoughtful design can make a small footprint feel complete.
