Heartwood in Seattle, Washington is redefining what’s possible for urban workforce housing.
As the first Type IV-C building completed as-of-right in North America, this eight-storey mass timber project delivers 114 homes – significantly more units than traditional light-frame construction allows – while maintaining a compact urban footprint.

Welcome
Greetings from your WoodWorks team. What are some of the challenges to wider mass timber adoption for new commercial and industrial buildings? We’ve all had experience with roadblocks we didn’t expect on the highway to growing the market. Some that spring to mind:
- helping clients to understand how mass timber buildings react to fire for the Maryborough fire station;
- speed of construction for Illawara Grammar School;
- achieving greater standardisation for greater QS cost control.
If you’ve got stories about overcoming these and other factors, or solutions your team is aware of, we look forward to hearing from you.
