New EXPAN Technical Design Guides

Home » New EXPAN Technical Design Guides


These Guides are based on the EXPAN system, which is the result of years of research and a unique collaboration between commercial and academic partners to create innovative structural timber solutions.

Combining all the strength and endurance of steel into the lightweight elegance and flexibility of timber, the EXPAN prefabricated construction system brings timber into the commercial and industrial design age.

EXPAN’s totally prefabricated technology cleverly embeds post-tensioned tendons into timber to lock the system together. The range includes revolutionary timber frame, wall and floor systems and quick-connect portal frames.

The Guide titles include:
