Room Additions That Tie In Without Leaks
The weak point of any addition is where new meets old: the roof valley, the wall joint and the floor line. We detail those joints before we design the rooms.
Up or out
Small coastal lots often leave no room to build out, so a second story is the way to add space. That means checking whether the existing foundation and walls can carry the load, and planning stairs that do not swallow a bedroom. Where the lot allows a ground-floor addition, it is usually simpler and less disruptive.
We look at both options with an engineer before you pick one.
Joining new to old
The new roof has to meet the old one with valleys and crickets that shed water. New stucco or siding has to lap over the old drainage plane, not sit against it. And the new floor has to line up with the existing one. Each of those joints gets its own detail on the plans, because those are where additions leak.
Matching the house
An addition should look like it was always there. We match rooflines, window styles, trim and exterior texture, and we tell you early if an exact match is not possible so you can choose a deliberate contrast instead.
Room Additions: questions
It depends on the foundation, the existing framing and your city's height and setback rules. An engineer's review answers the structural part, and we check zoning before design starts.
For a ground-floor addition, usually not. A second story often means opening the roof over occupied rooms, and you may want to move out for that phase. We plan the sequence with you.
An addition grows the main house. An ADU is a separate unit that can be rented or used by family. Permits, cost and what the space can be used for differ, and we can price both.
