Home Additions That Feel Like They've Always Belonged
Growing into your home shouldn't feel like an afterthought bolted on the side. We design home additions across the Greater Seattle Area — primary suites, family rooms, second-story expansions — that match the rooflines, the trim profiles, and the rhythm of the original house, so the new space feels like it's always belonged.
- Room, suite & second-story additions
- Permits & structural engineering handled
- Seamless tie-in to existing home
- Written 2-year workmanship warranty

A home addition built around how your family is growing
A home addition is one of the smartest investments a homeowner can make. Done well, it gives you the room you need today and adds lasting value for years to come.
Cost, disruption, and whether the addition will look like an addition — our process removes that worry with fixed estimates, careful tie-in detailing, and daily updates from start to finish.
More than extra square footage — additions reshape how your family lives long-term

Room Additions
Single-story bump-outs that add the specific room you're missing — without redesigning the whole house.
- Bedroom additions — for kids, guests, or downsizing parents.
- Home office additions — quiet, properly wired, with real storage.
- Mudroom & laundry expansions — solve daily clutter at the door.
Single-room addition vs. full home expansion
Add the one room you're missing without disrupting the rest of the home. Best when the existing layout still works.
- Single bedroom or office

- Tied into existing finishes
- Easier to stay in the home
- 8–14 week timeline
