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.

We asked Edward Thomas Construction to take down and build us a new fence. He was very timely and thorough. The price was very fair and the quality of work was excellent. Would recommend him and will most likely ask him to do work for us again.
