How it's designed
A modern detached backyard ADU, 600 sq ft inside, compact in shape: 1 bedroom and 1 bath, an open layout with a full kitchen, a stacked closet and 9 ft ceilings.
Outside: a shed roof in standing-seam metal, two-material siding in charcoal with natural wood trim, large picture windows in black frames, a sliding glass entry and a front deck.
Inside: standard finishes in a warm modern style, wood-look vinyl floors, wood flat-panel cabinets, white quartz counters and a walk-in shower. Heating and cooling by a ductless mini-split.
Pictured with golden hour light, pavers in gravel landscaping, three-quarter view and minimal styling. The setting is styling only, not part of the design or the estimate.
