If you asked me 2 years ago what I aspired to become when I would grow up, I would’ve answered “Engineer” without a doubt. As a kid I’ve always enjoyed making stuff and learning new skills. Joining architecture was a spur of the moment decision but Digital Design has made me realise that architecture is so much beyond design. In my perspective, it’s the best of both worlds; designing and creating.
Illustrator This subject made me sure that this is the field for me and I wish to specialise in Digital Fabrication in the future. During the final assignment for DD, I learned alot about data management in Grasshopper through trial and error.
Indesign Fabrication
In the future, I hope I can improve the thoughtfullness behind my designs as well as improve my graphical skills.

Diagramming Design Precedent My precedent study is the Serpentine Gallery Pavilion 2001 by Daniel Libeskind. In this pavilion, Libeskind uses origami techniques: valley folds and mountain folds to create various different thresholds within the pavilion. Repeated uses of the same fold type would create a long enclosed space like a coiled hallway whereas a sudden change in fold direction would result in arches and different thresholds. A good example of this would be at the start and end of the pavilion where there are different threshold conditions due to there being no solid ground plane and having low roofs.

Surface and Waffle
Panels used as interior cladding to brighten up the interior space via ambient lighting. Quarter isogrid waffle used as decorative facade as well as main structural component to hold the panels. Openings on the bottom face of each panel creates the opportunity for diffused light within the interior space.
Opening size of the panels are larger at the bottom and decrease in size towards the top of the volume.

During the creation of this design, I was experimenting wth various different ways of creating an interesting design through iterations of the waffle structure. My primary goal was to create a stable waffle structure. After I managed to achieve a good waffle structure, I tried to observe the potential architectural properties of the design and proceeded to iterate my design from there.

Task 01 Laser Cutting Linework
Because the design of my waffle structure is not a square grid waffle where the fins are perpendicular to each other, I had to make sure to give the notches abit more tolerance than the 1mm thickness of the material to compensate for the 60° connections between the fins.

3D printing top layers
Before 3D printing, I had to make sure that I had a “watertight� mesh before attempting to slice the 3D model in the slicing software. This particular 3D print was quite easy as there were no overhangs (design intention) and alot of bridging. All I had to make sure was that there was sufficient infill percentage so that the top layers do not span long bridges.

PEEL PAVILION
The concept of this design is to create a pavilion that flows seamlessly with the ground and creates a blurred threshold between the internal and exterior space of the pavilion. This is achieved through the twisting surface which forms both the roof and floor of the pavilion. Both the skin and the structure are weaved together such that neither is inside nor outside of the pavilion. The material used is sheet aluminium and rolled steel columns. Sheet aluminium is excellent at demonstrating the capabilities of developable surfaces to generate complicated designs out of

Isometric
The surface is twisted such that there is no clear distinction between exterior and interior surface.
The structural spine acts as a structural frame for the panels.
Concrete retaining wall follows the same language as the peeling surface to create a performance area.
Steel mesh limits the amount of light entering the internal space. The surface is created using panelling techniques. The fins are used to attach the panels to the structural spine.
Steel mesh reduces the amount of contact between the user and the cold material.
Reflective aluminium cladding
Timber seating provides a smooth gradual transition of materials between the metallic pavilion and the concrete stairs.

Design Iteration Number of consecutive lines tell me that there is sufficient headspace for people to walk under. (creates different thresholds)
When I was iterating the design for my pavilion, I was experimenting with the generation of various seating heights that was ergonomic for human usage.
Iteration 01
Based on a grasshopper script, I was able to generate solid lines at locations where the vertical distance between the end of each panel exceeded a specified height.
Parallel lines inform me of potential seating locations.
Using this script, I was able to freely change the profile curve of my surface and get immediate feedback as soon as the “frayed� sections of the surface were suitable for seating heights.
Iteration 02
In the diagrams to the left, you can see how I was able to filter through my iterations to determine which curve profile would be more suitable for seating. In Iteration 01(chosen), the number of lines at the lower end of the panels inform me that it would be possible to create a seating area. Furthermore, consecutive lines inform me that there is sufficient floor to celing height for people to walk under. (refer to annotations)

Design Iteration Surface normal direction informs how light reacts within the space.
Iteration 01
As I further developed the definition for my script, I experimented with the different properties of my pavilion. I initially attempted to use arrows to clarify the normal direction of the twisting surface. I realised that something as simple as an arrow can define alot within my pavilion and thus I chose to use it. Left: The normal direction at the edges of the panels determine where stairs would be suitable for the pavilion.
Relatively flat compared to ground, suitable walkway
At edges where the pitch is too excessive, stairs would be more suitable compared to a ramp. Right:
Iteration 02
The average normal direction informs me of the thresholds of the space. Depending on the angle of the normal directions, it would either become a walkway, a wall, a roof, or a seating space. The normal of the surface can also give me a good indication of light reflection when it bounces off the surface to illuminate the performance space in the pavilion.

Slope is too gentle. Unsuitable for seating as there is insufficient leg space for standing up or sitting down.

Fabrication process
Singly-curved ruled surfaces are considered “developable� and thus be able to be constructed out of paper.
Tabs at the back maintain the curve of the form as it is being constructed. Multiple snips are required on the tabs to relieve the stress.
25
Tabs are sandwiched between a pair of fins that hide the tabs as well as connect the panels to the 3D printed structural spine.
