Can your home support a second story?
Not every house is a candidate as-is. We evaluate the existing foundation and framing to confirm they can carry the added load, and where they can't, we engineer the reinforcement. This structural assessment is the first thing we do, because it determines what's possible and what it costs.
What the project involves
A second story means removing the existing roof, building new floor and wall structure, and re-roofing, significant work that requires structural engineering, permits, and careful weather protection while the house is open. On the hillside and view lots common in West Linn and Happy Valley, going up can also capture views a single story can't.
Living through it
Because the roof comes off, many clients move out for the intensive stretch of a second-story addition. We sequence the work and protect the home from weather to keep that window as short as safely possible, and we plan it with you before we start.
Frequently asked questions
- Can any house have a second story added?
- Most can, but the existing foundation and framing have to carry the extra load, or be reinforced to. We assess the structure first and engineer whatever support is needed before design goes far.
- Do I have to move out?
- For the stretch when the roof is off and structure is going in, usually yes. We protect the home from weather and compress that window, but a fully occupied second-story build is rarely practical.
- Is building up more expensive than building out?
- Often, yes: structural work, re-roofing, and weather protection add cost. But when your lot is tight or you want to keep your yard, building up is the way to get the space.
