5 out of 5 stars

We wanted a primary suite but our house is a 1920s Craftsman and we were worried an addition would just look stuck on. Luke brought in all the right details — matching siding profile, the trim style, the roofline tie-in — and the crew executed it perfectly. You genuinely can't tell the addition was added later, which is exactly what we wanted.

What we do

Home addition services

Room additions
Single-room expansions including family rooms, primary suites, sunrooms, and mudrooms added to your existing footprint. We tie the addition into the existing structure so it reads as part of the original house, not an afterthought bolted on the back.
Second-story additions
Full or partial second-story expansions on single-story homes, engineered to carry the new load properly. We assess the existing foundation and first-floor framing before committing to scope — if reinforcement is needed, we include it upfront rather than calling it a change order later.
Bump-outs
Smaller square-footage expansions that give a kitchen, bathroom, or bedroom the space it needs without a full addition. Bump-outs typically use cantilevered or extended framing rather than new foundation, which keeps costs down and timelines shorter.
Structural engineering
Engineered beam and foundation work required to tie the new addition properly into the existing structure. We work with licensed structural engineers and include their work in our contract, so you have one point of accountability for the whole project.

Frequently asked questions

Can't find the answer you're looking for? Give us a call .

How long does a home addition take?
Most room additions take 3-5 months. Second-story additions typically run 5-8 months depending on scope and permitting.
Do home additions require permits in Seattle?
Yes — all structural additions require permits. We manage the permitting process as part of our scope.
Can you match the existing siding and roofing?
We work hard to source matching or complementary materials. We'll show you options during the planning phase.
What structural work is involved in a home addition?
Most additions require new foundation work, engineered beams to tie into the existing structure, and roofline integration. We include structural engineering in our scope and work with the engineer throughout the build.
Can you add a second story to a single-story home?
Yes — vertical additions are more complex than ground-level room additions because they require reinforcing the existing structure to carry the new load. We assess the existing foundation and framing first and give you an honest picture of what's involved.
