The same plan can read coastal, contemporary or Spanish from the street. Here is how each plan in this series looks in one of its styles.
Spacious, comfortable layouts, privacy-minded floor plans, and storage that works hard–intentionally crafted for multigenerational living, entertainment, or long-term value.
Standardized plans, curated finishes, and repeatable processes mean fewer surprises, clearer schedules, and tighter budgets from day one.
Classically constructed, code-compliant, and locally inspected–delivering decades of performance and real growth to your property values.

"For an ADU, the way to go is with ActonADU as they design-build the project and work through all the permit hurdles. There are just too many details to work through that need the expertise of an org such as ActonADU to get things done well."
