Expandable Homes

Our expandable home units come in three different lengths; 20ft, 30ft, and 40ft — each built to last 20-30 years and can withstand up to category 8 earthquakes. Each shell is equipped with a full bathroom and the ability to add a full kitchen.

Expandable homes are assembled in San Diego, CA, shipped directly to the customer, and installed on-site. They can serve as standalone houses, ADUs, or even rental / AirBnB units (where local governments and permits allow).
