Trillium Architects

Trillium Architects is a full-service architecture and interior design firm that specializes in sustainable homes designed to reach Net Zero energy standards. The firm also takes on additions and deep energy retrofits that update existing houses while keeping their original character, along with commercial projects such as offices, retail shops and yoga studios, and multifamily housing.

The firm works through projects from schematic design through construction administration. Its homes are built with natural, non-toxic materials and use energy recovery ventilators to keep indoor air fresh. Trillium is an employee-owned co-operative, and it is based at 16 Bailey Avenue in Ridgefield, Connecticut.
