Prefab Cabins, Cottages & ADUs in Washington | Builders & Models For Sale (2024)

What's the difference between different kinds of prefab buildings?

There are four primary types of prefab buildings. Standard prefab homes are much like stick-built homes, only built offsite. Prefab tiny homes are smaller wheeled living spaces, similar to RVs. Offices, studios, and bunkies are usually one room buildings used for work or extra sleeping, and usually don't have any plumbing. Guesthouses (or cabins, cottages, or ADUs) are similar to prefab homes but are usually made smaller to act as a second home, weekend getaway, in-law suite, or rental property.
