NW Structures is a licensed and insured builder with 25 years of experience in Snohomish and King County. From a backyard shed to a detached garage or an ADU, you work with one builder from the first site visit to the final inspection, and we pull the permits.

What we build

Custom sheds

Storage sheds, workshops and backyard offices designed around how you’ll use the space, with the siding, roof and doors to match your home.

Shed installation & site prep

Already bought a shed? We clear and level the site, build the foundation and put it together right.

Detached garages & carports

One- and two-story detached garages, wood carports and RV covers, built to look like they belong with your house.

ADUs

Detached accessory dwelling units for family, guests or rental income, from design to final inspection.

Extra living space

Bonus rooms and home additions when you need more room without moving.

New home construction

Custom homes built by the same crew, with the same communication from start to finish.
