Great Room Addition in Kirkland, WA
Xion Build provides expert great room addition in Kirkland. As a trusted Kirkland home additions contractor, we manage design, materials, permits, and every trade in-house so your project stays on schedule and on budget. A large open living and entertaining space.
Kirkland's waterfront cottages and hillside homes mix tight lots with big design ambitions — we plan access, staging, and finishes accordingly.
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.
