About Us

Biophilia, Biomimicry, and Place-Based Regenerative Design

McLennan Design is a regenerative architecture, planning, design and product design practice focused on deep green sustainability, community and education.

McLennan Design was formed in 2013 as a new firm dedicated to the creation of Living Buildings, Net-Zero and Regenerative Projects. Founded by global sustainability leader and green design pioneer Jason F. McLennan, the firm brings institutional knowledge and expertise of the Living Building Challenge, and the host of related programs, unmatched in the A/E industry. Joined by partner Dale Duncan, AIA, the firm is experienced in virtually every building type, domestically and abroad.


The world is complex – we recognize that by working together we can accomplish great things and make a positive impact on things more than we would achieve alone.

Everything that we do comes from a place of love.

Love of the planet, love for our families and children, love for future generations, love for all of life. It is love that motivates and drives what we do.
