Portland Tiny Home Plans (Custom Projects)

20 Twenty SMI devotes 10% production time to specialty projects. Our simplified R&D process takes a new concept from design to completion. Whether intended to be mobile or installed on-site, when the structure leaves the factory it’s days from being fully functional. Specialty projects involve more intensive collaboration with the customer so additional fees apply, but it all begins with our customer’s great idea.
