What's included in your garage addition

A typical garage addition in Woodinville can involve finishes, windows, framing, roofline tie-in — and we put the full scope in writing so you know exactly what's covered before work starts.

A home addition lives or dies on the connection to the existing house — foundation, framing, and rooflines have to marry seamlessly so the new space feels original.

Most garage addition projects in Woodinville fall between $49,500 – $149,000, depending on the size of the space, the finishes you choose, and the condition of what's already there.
