Questions we get

What people actually ask.

Can we add a second story to any house?

Most. Foundation, FAR, and hillside rules decide. We tell you in week one.

How long is the new room unusable?

Six to twelve weeks for a single room addition. Three to six months for a second story.

Will the new part match the old?

Yes. We document the existing finishes and source matches.

Can we live there during?

Usually yes for additions. Not always for second stories. We will be honest.
