Commercial Mass Timber

Are you interested in mass timber for your commercial project?

Cornerstone Timberframes is a family-run business dedicated to building custom timber frame structures of exceptional quality and beauty for clients across the USA and Canada.

The Cornerstone team is made up of dedicated, creative, detail-obsessed craftspeople. We enjoy discovery and learning new techniques and are always asking how we can improve what we do.

A revolution is underway that is renewing our craft, allowing timber to reach farther, while adding greater accuracy, innovative possibilities, and sustainability to what we build and where we build it.

Our clients are as varied as their projects, from homes and cottages to mid-rise residential buildings and large commercial spaces.  Whether they are homeowners, builders, or architects they share a love of big wood and a desire to see the structure in the places they build.  It’s our privilege to serve you!

At Cornerstone, we are thankful for the communities where we work and serve, our trusted network of designers, builders and suppliers, and this beautiful planet that calls us to be more responsible in the resources we use.
