Exploring construction using whole trees

Exploring construction using whole trees

Researchers at the Forest Products Laboratory (FPL) are testing trusses, which provide structural support for buildings, made from whole trees. One such truss had a clear span of 16.7 metres and was made from low-value red pine logs. 

This work, which is a cooperative effort between FPL and Whole Trees, is being conducted to demonstrate the technical feasibility of using tree stems, in their original form, as structural members in commercial structures.

“We’re engineering the tree into structural assemblies which make use of the tree’s superior strength in bending when compared with milled wood. This will lead to stronger buildings while adding value to forests,” said Roald Gundersen, co-founder and project lead at Whole Trees.
