01 Overview

The best additions are invisible — they extend a home without ever interrupting it.

Need more room for your family, a home office, or guests? A well-designed addition lets you stay in the neighborhood you love while gaining the space you need.

A great addition looks like it was always part of the house. We match rooflines, materials, and finishes, and we coordinate engineering and permits so your project is done right.

Do I need a permit for a home addition?

Yes. Home additions require permits, and we coordinate the plans and permit process with the City of Pasadena.

Can the addition match my home’s style?

Yes. We match materials, rooflines, and architectural details so the addition blends in naturally.

Can you build a second story on my house?

In many cases, yes. It requires a structural evaluation, which we coordinate before design begins.
