ADUs

Accessory dwelling units have become one of the most effective ways to expand living space, increase property value, and create long-term flexibility. UMI Seattle designs and builds custom ADUs that serve a wide range of needs, from rental income and multigenerational living to private offices or guest spaces. We handle the entire process, including feasibility, design, permitting, and construction, delivering efficient layouts, green design, and high-quality finishes that make the most of every square foot. If you are looking for a smart, future-focused investment in your home, an ADU offers options that few other projects can match.

Home Additions

Home additions are a powerful way to maximize your property’s potential and create space that truly works for your lifestyle. UMI Seattle specializes in strategic expansions, including garage and basement conversions, thoughtfully planned bump-outs, and custom additions that add meaningful square footage without compromising flow or design integrity. We evaluate what is possible on your property and deliver smart, high-impact solutions that increase usability, comfort, and long-term value. If your home no longer fits the way you live, a well-executed addition can transform it into one that does.
