A modern detached backyard ADU, 450 sq ft inside, compact in shape: a studio and 1 bath, an open layout with a full kitchen, a stacked closet and 10 ft ceilings.

Outside: a flat roof in flat membrane behind a parapet, lime plaster siding in warm white throughout, steel-grid glass windows in black frames, a french doors entry and a slab steps.

Inside: standard finishes in a warm modern style, polished concrete floors, wood flat-panel cabinets, concrete counters and a walk-in shower. Heating and cooling by a ductless mini-split.

Pictured with dusk light, pavers in gravel landscaping, front view and minimal styling, staged as a home office. The setting is styling only, not part of the design or the estimate.
