The project involves the construction of a timber wood structure along the Eagle’s Nest Mountain Trail near Madawaska in Ontario. The project oversees the experimentation of steam-bending wood in both one and two axes. It explores the integration of columns and diagonal grids (dia-grids) systems to create a harmonious structure that considers both structural integrity and design aesthetics.

To connect the different systems, the project employs various joinery techniques such as the three-way lap joint, diagonal cut lap joint, scarf joint, and mortise and tenon joint. The structure overlooks the trail with three cantilevers stacked atop each other, featuring leaf-shaped floors designed to embrace the natural surroundings.

The diagram above illustrates the various types of wood bending in glulaminated beams derived from bent boards. It shows top, bottom, and longitudinal cuts of the beam. This type of wood bending was implemented in the assembly of the leaf structure.

The team tested prototypes using 3D printing for specific components and CNC machining of a part of the cantilever at a scale of 1:1. Further, the team tested steam-bending methodologies to achieve the vertical bending of the cantilever. Further, the team investigated lasercut prototypes of the entire model. The aim was to find the best technique to achieve the organic form of the structure.

The two lower cantilevers are suitable for walking, whereas the uppermost cantilever serves as a protective structure for the ones below. This method of layering explores the integration of columns and wooden structures to form a cohesive system rather than distinct entities.
