Home design for the rest of us.

Studio DEC is a full-service design firm based in Seattle, Washington. We specialize in residential remodels, additions, new home construction, and Backyard Cottages, aka DADUs. Our project portfolio ranges from budget-friendly kitchen renovations and front porch additions to the design of backyard cottages and entire homes. We are a small firm with a strong emphasis on direct client communication and listening. Our team is committed to sustainability: we believe that the greenest solution is often the most economical solution as well, whether that means taking advantage of rebates on energy-efficient appliances or practicing passive solar design to keep heating bills low.  We use state of the art 3d design software that lets us and our clients visualize the design of their project inside and out.  Our strong background in residential construction and sustainability insures project success both in terms of cost and design goals.
