Through experimentation and research, the goal is to explore different skin types, understand their properties and create a unique design that enhances the gridshell structure.

The Cloud

The Cloud is an iconic fabric membrane structure commissioned for the 2011 Rugby World Cup in New Zealand. It is a 178.5m long curvaceously-shaped structure. It is sculpted in a clear ethylene tetrafluoroethylene (ETFE), following its natural contour and creating a floating presence.

Centre Pompidou-Metz

Museum of modern and contemporary arts located in Metz, France. The building is remarkable for its roof structure. The entire wooden structure is covered with a white fibreglass membrane and a coating of teflon, which has the characteristics of being self-cleaning, protect from direct sunlight while providing a transparent at night.

Materials

Fabric

Light weight, flexible and versatile in shape and structure. It is typically cheaper than other materials and provides an easy construction. Moreover, fabric’s transparency allows maximum daylight to filter through it.

-Polyesters

Polyester is the most frequently used base material because of its strength, durability, cost and stretch.

-Spandex

Difficult to use in long-term exterior applications because it tears easily. And its chemical composition makes the material highly sensitive to heat; therefore easily damaging its structure.

Plastics

Polyethylene (HDPE)

Most common type of plastic. It is known for its large strength to density ratio; lightweight structure, cheap, and long-lasting.

-Styrene

Material that provides high-performance characteristics, quality and cost-effectiveness. Some of its benefits include strength, durability, and lightweight.

-Poly Keder

This durable 17-mil polyethylene plastic is designed with enclosed air bubbles. Its unique poly film does not yellow, streak, or get brittle, and maintains it’s light transmission properties for an unprecedented amount of time. It is a long last material cheaper than glass or acrylic.

-Calendered Vinyl

The vibrant colors, the high opacity, the lightness, and the exceptional high gloss are the key features of calendered film.

Metals

-Aluminium 

Great material that can be bent, cut, drilled, punched and easily shaped to achieve complex designs. It is long lasting with excellent weather resistance properties.

Skin 1

In the first model, we used a four-way stretch fabric to create the skin. The fabric membrane structure maintains its simple aesthetic appeal, functionality and minimal maintenance.

Skin 2

The second skin is a circular panelization that is attatched at each intersection point of the grid, allowing for flexibility in the structure design. The panels overlap to create a more dynamic pattern.
