Modular Builders Inc. (MBi Building Systems) is a family-owned Iowa Corporation at the forefront of Offsite & Prefab construction. In addition, we are leading the charge in construction services for TinyMod™ and revolutionizing the construction and distribution of Affordable Housing and Accessory Dwelling Units (ADUs). Our team has boasted a robust legacy spanning over 40 years in the home building and systems-built industry and has successfully led and collaborated with some of the top companies in America, contributing to nearly $1 billion in projects spanning hospitality, commercial, mixed-use, single-family, and multi-family units across North America.

MBi Building Systems is dedicated to helping families and assisting developers, with Prefab and off-site construction opportunities. In 2017, our micro-designs where developed to meet the urgent needs of lower-income families, and the first IRC TinyMod was built in the State of Iowa—an innovative 598-square-foot micro-home. This project gained notable recognition and financial support from the USDA Rural Development as part of a broader initiative addressing affordable housing in the Midwest.
