As Featured In

We build for the way the Northwest lives.

For 30 years, LastingNest has built and remodeled Pacific Northwest homes made to last — beautiful, durable, and better for the climate we build in. We're the builder architects trust to protect the vision, and the one homeowners call when they want it done right.

What We Do

Thoughtful updates and additions that make older homes look like new. Kitchens, baths, and additions built with a 90% jobsite recycling rate, low-VOC finishes, and detailing that lasts for decades.

For architects & designers

A builder who protects the vision.

We read a drawing set the way you do: fluent in the details, quick to flag what won't work before it's built, and a real collaborator on constructibility, materials, and green-building strategy. The builder who sees your project through an architect's lens.
