Refine Design Architecture is a licensed residential architecture firm serving homeowners throughout Washington State—including Snohomish and Snohomish County. As your dedicated DADU architect, we bring a proven process, deep design expertise, and a genuine commitment to getting it right. Snohomish is a community rich with character—from its historic downtown and agricultural roots to its forested hillsides and river valley setting. That context matters to us. When we design a DADU in Snohomish, we're not applying a generic template. We're studying your specific lot, your neighborhood's scale, your views and solar access, and the way you want to live—then crafting a detached accessory dwelling unit that feels like it belongs exactly where it is. Our team guides you through every phase: pre-design feasibility, schematic design, construction documents, permit submittal, and construction coordination. We understand Snohomish County's zoning codes and the nuances of building in this region—whether your property sits within the city limits or in the unincorporated county. DADUs are one of the most impactful investments a Snohomish homeowner can make, and the design decisions made early in the process shape the outcome for decades. Partnering with a licensed DADU architect ensures those decisions are made thoughtfully, efficiently, and with your long-term goals in mind. Let's design something worth building.
