Planning an addition
Does a home addition need a permit?
Yes. Additions require a building permit, and some projects also need planning review. We confirm the requirements for your lot and handle the submittals.
Addition or ADU?
An addition expands your existing home. An ADU is a separate living unit with its own entrance. We help you compare both for your lot and goals.
Design and process
Will the addition match my house?
That is the goal. We plan rooflines, materials and finishes so the new space blends with the existing home.
Do you offer design services?
Yes. Our in-house designers create the plan, and we use 3D modeling so you can see the result before construction begins.
