Two-Story Great-Room Expansion in Seattle, WA
When Seattle homeowners search for two-story great-room expansion or a dependable home additions contractor near them, they want craftsmanship that lasts and a crew that communicates. That's exactly what we do. Vaulted, two-story living additions with structural steel where needed.
From Laurelhurst to Queen Anne, Seattle's older homes often need structural care alongside the kitchen, bath, and addition work that modernizes them.
From room additions and bump-outs to second stories and full primary suites, we handle structural engineering and permits up front so there are no surprises.
What's included in your two-story great-room expansion
A typical two-story great-room expansion in Seattle can involve insulation, roofline tie-in, finishes, framing — 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 two-story great-room expansion cost in Seattle?
