ABSTRACT This project revolves around the exploration of a combination of two materials: steel and fourway stretchable fabric. The steel stands as a stiff column and the fabric works like a wall By anticipating different modules and combining a series of angles to attain a self-standing structure that provides sufficient space for an exhibition with a capacity of a minimum of fifty people. To be able to access this place the goal is to let sunlight penetrate inside for min 5 hoursv

Materials: cycle spoke, Lycra four-way stretchable fabric spoke size: L-300mm DIA-2mm spokes are joined by a gas welding formatting triangle of 300mm long edges.

cycle spokes

gas welding

The spoke triangle is to be bent from the center of each edge and one-third points of each edge The fabric cut into the desired shape with the size of 200mm of each edge is then attached to the formed and joined points of the module.

1) Bent from the center point of each edge

2) Bent from one-third point of each edge

The fabric is attached to spokes by a thread.

Through this process, a self-standing single structure has been achieved, Taking numerous structures like this and combining them in such a way that creates a pavilion type space
