Deattached Accessory Dwelling Unit Remodeling Company in Seattle, WA

Turn unused backyard space or a detached garage into a thoughtfully designed extension of your home. Lux Design Builds creates custom detached ADUs in Seattle, WA, helping homeowners develop comfortable, functional spaces that complement their property and support changing lifestyle needs.

Also known as DADUs or backyard cottages, detached accessory dwelling units offer a separate structure from the primary residence. Whether you are considering new construction or a detached garage conversion, our design-build team can help shape the project around your vision, property, and priorities.

What Is a Detached Accessory Dwelling Unit?

A detached accessory dwelling unit is an independent residential space located separately from the primary home. Depending on your goals and project scope, a DADU can incorporate living areas, a kitchen, bathroom, sleeping space, storage, and carefully selected finishes that make the interior feel complete.

For Seattle homeowners seeking additional usable space, a backyard cottage can provide flexibility while allowing the new structure to have its own character and sense of privacy.

Transform a Detached Garage Into Living Space

An existing detached garage may offer an opportunity to rethink space that is no longer serving your household. A detached garage conversion can create a comfortable living environment with updated flooring, insulation, lighting, electrical systems, plumbing, and interior finishes.

Lux Design Builds brings the same thoughtful planning to these projects as our broader Seattle interior remodeling services, with an emphasis on function, cohesive design, and quality craftsmanship.

Custom DADU Design for Seattle Properties

A successful detached ADU should feel intentional from the start. Our design-build process considers layout, storage, natural light, finishes, and everyday functionality while helping you visualize how the completed space will work with your property.

For homeowners coordinating a DADU with larger renovations, our full home remodeling services provide another way to create a more unified design throughout the property.

More Ways to Use Your Backyard Space

Your detached ADU can be planned around the way you expect to use it, whether that means accommodating guests, creating flexible living quarters, or adding a private retreat separate from the main house. Thoughtful exterior planning can also help the structure feel connected to surrounding outdoor areas. Explore our Seattle outdoor living services for additional ideas.
