Home Additions
Home Additions built by Greg
Moving to get more space means a new mortgage, a new commute and giving up a place you already like. An addition keeps the address and fixes the house instead. Maybe it is a primary suite so you are not sharing a hallway bath, a family room for kids who have outgrown the living room, a bigger kitchen, or space for a parent moving in. The hard part is making the new section look and work like it was always there, inside and out.
Additions are a specialty for Greg Myers, and over 33 years of experience he has framed and finished everything from ramblers and two-story homes to large custom builds. On an addition he handles the whole job: design help and drawings, permits, excavation, the concrete foundation, framing, tying the new roof into the old one, siding and windows matched to the house, and all the interior work through final trim. Because you work directly with Greg, the person who walks your lot at the estimate is the one building it.

What's included
Home Additions: what's included
- 01
Room and bedroom additions
A new bedroom, office or family room off the side or back of the house, sized and placed for how you live.
- 02
Primary suite additions
A bedroom with its own bathroom and closet, often the most wanted addition in a house with one shared bath.
- 03
Second-story additions
Building up instead of out when the lot is tight, with the existing walls and foundation checked for the added load.
- 04
Kitchen and great-room bump-outs
Pushing out an exterior wall to give a cramped kitchen or living room the room it needs.
- 05
Foundation and site work
Excavation, footings and a concrete foundation or crawlspace done in-house, with drainage planned for wet ground.
- 06
Matched roof, siding and windows
The new roof ties into the old one and the siding, trim and windows match, so the addition reads as part of the house.

Questions
Home Additions FAQs
How much does a home addition cost?
It depends mostly on size, whether it is a ground-level or second-story addition, and what goes inside it, since bathrooms and kitchens take more work per square foot than bedrooms. Site conditions, the foundation and how much of the existing house has to change also play in. Greg prices each addition after a free on-site visit.
Does Western Washington weather or soil affect an addition?
Both do. Clay and glacial till soils drain poorly and high water tables are common, so footing drains and grading away from the house matter. The rainy season also shapes the schedule, so we aim to get the frame roofed and wrapped quickly to keep the inside dry.
Is it better to build up or out?
Building out is usually simpler when you have the yard, and the rest of the house stays livable during the work. Building up makes sense on a tight lot or when you want to keep the yard, but the existing foundation and walls have to be checked for the extra weight. Greg will look at both options at the estimate.
Do I need a permit for an addition?
Yes. Every addition needs a building permit, and rural lots can also bring setback, critical-area and septic capacity questions when you add a bedroom. Greg handles the permit and inspections with your county or city.
Will the addition match my house?
That is the goal on every addition. We match the roof pitch, siding, trim and windows where those materials are still available, and choose something that complements the house where they are not.
