Dwell magazine, one last thing Nov/Dec 2018

“For 20 years, Los Angeles designer and professor Jennifer Siegal has been pushing the limits of modular housing through her firm OMD, most recently with a series of prefab accessory dwelling units just released this fall.”

Our prefabADU® can be established on properties where there is an existing or proposed primary single-family residence. We provide homeowners with rental income and additional space for family members or caregivers. Each of our three turn-key models includes kitchen, bathroom, bedroom, living room and laundry. Built in California, our smart homes meet the highest national energy efficiency standards.

Our designs are inspired by the Shakers who believed in quality, integrity and reliability.
