ADU & DADU Construction
Add flexible living space, privacy, or rental potential with a custom ADU or DADU designed for your property.
Our Approach
An accessory dwelling unit can give your property room to adapt. NW Build designs and builds attached ADUs and detached DADUs for guests, extended family, multigenerational living, home offices, or rental use throughout Bellevue and Puget Sound.
We help move the project from early ideas through planning, permitting, construction, and final finishes. Each unit is designed to fit the site, meet its intended use, and feel like a natural part of the property.
Smart Space for the Way You Live
From a private guest suite to a fully independent backyard home, we plan efficient layouts with the right balance of comfort, privacy, storage, and daylight. The goal is more than extra square footage: it is useful space that works for your household.
A Grounded, End-to-End Build
Site preparation, foundations, utilities, structure, interiors, and finishes all need to work together. Our team coordinates the details so your ADU or DADU is thoughtfully built, visually connected to its surroundings, and ready for the next chapter of your property.
