Prefabricated ADU kits that fit Massachusetts’ new ADU regulations as a result of the Affordable Homes Act. The Flora 900 SF model maximizes the amount of space allowed through the new regulations, and is built with healthy, sustainable materials that result in net-negative carbon emissions.

The demand for high-performance homes is growing nationwide as homeowners and developers seek energy-efficient, durable, climate-resilient and comfortable buildings. But this surge in demand has revealed a critical bottleneck: a shortage of trade contractors skilled in high-performance construction. As this gap widens, innovative solutions like high-performance small home and accessory dwelling unit (ADU) kits are stepping in to bridge the divide.

A modular home or ADU kit is predesigned, pre-fabricated, and simplifies permitting, saving you time, money, and a lot of headaches.
