The Project

Project Overview

A new-construction detached accessory dwelling unit (ADU), built from the ground up in a Los Angeles backyard: new foundation, framing, utilities, and a fully finished interior. Inside, the unit has a modern custom kitchen with a stone island, wood cabinetry, and stainless steel appliances, along with its own bath and living space. It stands on its own as a complete second home, and the main house keeps its privacy.

Why homeowners build a detached ADU in Los Angeles

A detached ADU, sometimes called a granny flat or in-law suite, is one of the best ways for Los Angeles homeowners to add real living space without moving. Because it sits apart from the main house, it works well as a long-term rental, a home office, or room for family, and it adds lasting value to the property. The goal is a unit that feels like a real home from the day you move in.

How we build a detached ADU, from foundation to finish

We build every detached ADU from foundation to finish and permit it through LADBS, so it is fully legal and inspected. Most of the detached ADUs we build in Los Angeles are finished in about three to five months, depending on the size and the site.
