I have chosen to focus on Geometry as my research field, as this is a field that offers a look into the constructability of the designed form, and how this - despite it being considered to have quite a minimal surface and rigid form - can influence both the materiality and sustainability factor of the overall design. I believe that this is a fundamental way of not only utilising computational software for the purposes of this project, but also of seeing what can be achieved using digital fabrication processes.

In this case while the form is not quite rigid, the framing and skeletal structure of the obejct gives the main say on the types of materials able to be used, as well as limiting this to materials that will achieve minimal surface area and maximal volume. As such, the Green Void is a structure made out of specially treated hight-tech Nylon (with lighting elements), giving it a surface area of 300 sqm, and a total volume of ten times its surface area, in other words, 3000 cubic m 2. This achievemnt can be seen to have been achieved primarily through the use of parametric modelling and design in the field of Geometry, and the playing around or manipulation of it.

case study 1.0
This project consists of a 3D lightweight structure focused on exhibiting minimal surface tension capabilities within an indoor void of 20m in height1. This is particularly interesting as it highlights the object’s ability to be sustainable and use a minimal amount of materials and time for fabrication in order to produce maximum visual and aesthetic effect within a large space.

By using lightweight materials in its design, the canopy was able to achieve a hierarchy of volumes underneath it as well as a variation of space amongs the seating sections. Besides providing shelter for spectators, the canopy’s use of predominantly transparent materials allows for a connection with the outside as well as with the rest of the Olympic park surrounding the structure. The canopy was constructed as stated above using lightweight acrylic glass and steel cables, which were mounted on large steel poles in order to hold the canopy up. Working predominantly with tensile forces, the canopy is an excellent example of a type of almost rigid mesh relaxation technique on a large scale, while the use of the engineer Otto’s algorythmic designs allowed for a more controlled outcome of the fabrication processes, something that was innovative for its time. Such a structure achieves complex and dynamic form in its design, while also creating a new sense of ornamentalism through geometric design.

Olympiastadion Gunther Behnisch & Frei Otto Munich, Germany 1972
case study 2.0
The Munich Olympic Stadium, known as the Olympiastadion in German was a revolutionary structure in its day, utilising algorythmic geometry along with the use of materials such as acrylic glass and steel cables for its canopy. The canopy in particular was designed to simulate the form of the Swiss Alps, and to mimic their peaks and undulations in its geometry.

KEY REASONS FOR SITE CHOICE:
• Accessible to a wide range of people due to proximity to main road, housing estates and train stations. • Already a widely used skate park on the other side of creek – wide exposure – and may bring more from different target audiences. • Adversely, the specific areas on site to be used have been underutilised unlike the skate park. • Opportunity to hang and anchor design from many points of both the bridge and the staircases/supporting structure. • Opportunity to incorporate the built and natural environments present on site.

Using wire mesh and inset panels of translucent, coloured plexiglas, this design demonstrates the potential of something as rigid as wire mesh in forming quite flowing geometric shapes, which then allow for the play of light to occur in combination with the plexiglas as mentioned.
Constructed out of a series of panel elements in order to create a relaxed mesh form, this project aims to explore the relationships between geometry, performance, organization and fabrication of the work as a whole.

prototype: Prototype created in a shell geometry, designed to mimic an open cocoon shape. Design should be anchored on three points to above bridge trusses.
elements/materiality: Created out of 0.5mm acrylic elements in three different shapes: an X, a Y and an I shape. Held together using splitter pins, to give rotational ability while still retaining an element of rigidity give predominantly from the individual acrylic pieces.

conceptual inspiration • Interest: Concept of creating a pliable relaxed mesh surface out of individual and quite rigid elements in order to form the resulting geometry of the project. • Reasons for choice: - Durability - Further play with geometry of individual elements - Materiality
