Moving toward a cleaner, sustainable future

Our vision is to accelerate the use of mass timber in construction to deliver sustainable, net-zero-emission building solutions to improve the environment on a global scale.

Green City

Our Vision

Creating healthier, more equitable cities

Affordable housing is a much-needed resource in our cities, and we are committed to making our products accessible for all. Because mass timber acts as both structure and finish, good design won’t get cut with the budget.

Our Values

The work we do is rooted in our values of equality, innovation, and integrity

We believe that everyone has the right to live in safe, healthy, and thriving communities and are committed to making mass timber accessible and affordable.

By harnessing the latest technology, we are spurring policy reform and creating a healthier planet and more resilient communities.

To build a better world, we must hold ourselves and others accountable. We do what we say we will do, and uphold the highest standards of integrity within our team.


We are innovators, researchers, and changemakers
