It's really that easy! Our standard customizations are detailed on the Extras page. However, we're custom shed builders and have experience with specialty requests such as metal siding, large format glass windows and doors, iron work for decks or whatever you dream up!

ABOUT US

Hello! I’m Ethan Beyenhoff, and together with my longtime friend Javier, we run Beyenhoff Builds, LLC. We’ve built homes, remodeled spaces, and crafted backyard studios to help homeowners maximize their properties.

A backyard studio is a fast, affordable, and hassle-free way to add space without moving. That’s why we created Shed Lab Northwest—focusing on high-quality, functional builds that help you stay in the home you love.

We take pride in our craftsmanship, using only premium materials to ensure lasting durability. From custom backyard studios to custom shed kits, we’ve got you covered.

Check out our work and reach out with any questions. Let’s build something great together!

Based in Bellevue, WA, we proudly serve the Eastside and Seattle.
