Questions families ask before adding on
In most additions, yes. We plan the work so the main rooms stay usable, seal the opening into the old house until the new room is closed in, and talk through the noisy days ahead of time.
It depends on the lot. Building out needs yard space inside the setbacks. Building up needs walls and a foundation that can carry a second floor. We check both at the first visit.
That is the goal. We match the roof pitch, the wall finish, the window style and the trim so the new room reads as part of the original house from the street.
Yes. We prepare the drawings and engineering, submit them to the city or county, answer the plan check comments and schedule the inspections.
Outgrowing the house? Add the room instead
Tell us who needs the space and where the house is. We will set up a visit and talk through what the lot allows.
