This Hawthorne ADU conversion turned a 380 sq. ft. garage into a 550 sq. ft. ADU at the back of the property. RnD Builders Inc added high-end finishes and a bright, open layout. As a result, an unused garage now works as a comfortable, independent home.
A 10-foot French door with side light panels fills the space with daylight, and a 5-foot pass-through window connects the kitchen to the outdoors. The kitchen has white shaker cabinets, a subway tile backsplash, black hardware and stainless appliances, set on light wood vinyl plank flooring. In addition, the bathroom has a walk-in shower with large-format marble-look tile and a hexagon mosaic floor. Recessed lighting keeps the white interior bright from room to room.
Our design-build process
Like every RnD Builders project, this ADU conversion project followed our four-step design-build process. First, we learn your goals, style, budget and timeline. Next, our in-house design team creates custom plans and 3D renderings. Then one licensed team handles the plans, permits and construction, so the schedule stays on track. Finally, we walk through the finished space with you and review every detail.
RnD Builders Inc is a family-owned design-build contractor based in Woodland Hills and serving homeowners across Los Angeles and Ventura County. Our work has earned Best of Houzz awards from 2022 through 2026. Every home is different, so we start by listening. We then build a plan around your goals, your budget and the way your family lives, and we keep the schedule clear from day one.
