Friday Harbor is in San Juan County, Washington, and Refine Design Architecture serves it as part of serving homeowners across Washington State. We don't start with assumptions about your street. We start with your site and your goals. Adu Design for us means licensed residential architects who ask why you want the unit, whether that is passive income, downsizing, or space for extended family. The answer shapes the size, the layout, and how the ADU relates to your main house.
Our Adu Design services cover accessory dwelling units, mother-in-law suites, and other additions such as home offices. We design suites and ADUs as self-contained units with a kitchenette, bathroom, and living space. Early on we offer feasibility studies and site analysis that look at topography, drainage, access, and zoning restrictions. As part of the site application process we often prepare a draft site plan showing the anticipated locations of major utilities and improvements. We also provide 3D modeling and construction drawings for builders. If you are considering Adu Design in Friday Harbor, contact us to schedule a consultation.
