Expert Home Additions in Spokane County, WA

Edward Thomas Construction handles home additions across Spokane County, from single-room expansions to full second-story builds. As a sole proprietor LLC and licensed general contractor, we manage every phase of your project directly. No handoffs to unknown subs. No gaps in communication. Spokane County's housing stock includes a wide mix of Craftsman bungalows, mid-century ranches, and split-level homes. Each style carries its own structural considerations when adding square footage. We assess your existing footprint, your lot setbacks, and how the new space connects to what you already have. Many homeowners in Spokane County choose to add rather than move because local inventory stays tight and moving costs are high. A well-planned addition gives you the space you need while keeping you in the neighborhood you chose. We work with homeowners on bedroom additions, family room expansions, master suite builds, and garage conversions. Call Edward Thomas Construction to talk through your project.

This construction company is small and personal. They built a new porch on the front of our house, and we absolutely love it. We were given choices during the build and are very happy. The crew was friendly and worked very diligently.

Ruth Lenz Google review · July 2026

Edward and his crew were very efficient and cheerful. Edward gave a fair written bid and stuck to it. I have used his services twice and will probably continue to do so.
