What's included in your home office addition
A typical home office addition in Bellevue can involve finishes, roofline tie-in, insulation, foundation work — 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.
How much does a home office addition cost in Bellevue?
Most home office addition projects in Bellevue fall between $45,000 – $135,000, depending on the size of the space, the finishes you choose, and the condition of what's already there.
