About Boxx

Design / Build

Boxx is a design-build firm in Wilton, Connecticut. Our team has worked with structural insulated panels since 2013 — including three years manufacturing them ourselves — and every Boxx ADU is built from the same high-performance panel construction.

Each model is fully engineered before we offer it, so the plans, the permitting and the build come from one team rather than three. That is why a Boxx ADU can move from signed contract to finished building without the gaps that usually open between architect, engineer and contractor.

Our team is committed to delivering innovative and sustainable ADU solutions tailored to meet your needs.
