According to Zeara-Polo, the diagram does not play a representational role in the design process but provides an organisational and can have a performative quality depending on how it is deployed. Explain how Diagram is different from Signs and Symbols? (100 words Maximum)
Diagram usually relates to either specific space, specific location, scale or temporal frame. It is a tool that can describe relationships and prescribes performances in space. Diagram always has a spatial correlation whereas signs and symbols often play a representational role for their dynamic object. Diagramâ€™s reductive nature refers to precise defining. A simple diagram may generate very complex organisations or can be interpreted in various ways.

Top Left: Elevations and plan images placed on 4 sides. Top Right: Work in process of planes extracted from the outlines of the elevations. Bottom Left: Extrusions on completed planes I started modelling the precedent by laying out the elevations and plan on rhino according to the faces they are depicting. When I was laying the images, I realised that the images do not match perfectly. Therefore, I chose to model the precedent following the south and west elevations while others as a reference for the overall shape and form of the pavilion. I traced the elevations and started to model each plane one by one. After all the planes are completed, I tried “Loft” and “Sweep1” command but they did not work. Therefore, I decided to use “ExtrudeSrf” and polysurfaces to add thickness to the planes. Lastly, I added a platform for the internal spaces of the pavilion referring to the image above.
Reading: Hertzberger H. 2005. The in-between and The Habitable Space Between Things, from Lessons for Students in Architecture. Herzberger discuss how design should not be extreme in its functionality. Use your precedent study to explain how the pavilion allows for an appropriation of use. (100 words Maximum)
The pavilion can function as a lecturing space or a cafe. The overlapping folds can create shelter for the visitors of the gallery or passerby to stay inside. Visitors might include students or children. The pavilion is suitable for a temporary learning space for them. They can position themselves towards the centre (fully covered) or the openings (for sunlight) to suit themselves for a comfortable learning environment. Also, it is possible to set up a cafe within the Pavilion. The cafe would be next to the gallery while it can be set up in both sheltered and outdoor areas.
Isometric (SW) of Libeskind Serpentine Pavilion The modelling of the Libeskind Serpentine Pavilion is complicated. Since it is structured as multiple angular overlapping folding planes, modelling and connecting the extrusions and internal structures was challenging. In the middle part of the pavilion, the folds are very clustered together. Therefore, while I was modelling the ribs of the internal structure, it became really difficult to distinguish the direction, angle, placements and connection of them. The modelling process was much easier done with lowered transparency. Through the process, I have become more familiar with Rhino commands such as “Extrude”, “SolidPtOn”, “Trim” etc. from the repetitive usage of them. When I was modelling the ribs of the internal structure, I referred to photographs of the actual pavilion to try and achieve an accurate replica of the actual pavilion. Although the internal structures are modelled in detail, most of them are not shown in the isometric view since they are very crowded. However, they are shown in one of the diagrams displaying the overall pavilion with the internal structure. During the modelling process, there are very clear routes for people to circulate through the pavilion. While there are multiple thresholds, there are a few in particular that is predicted to have more people to enter and exit from. The folding of planes define the spaces. As two planes reach the ground, it creates a short tunnel. The narrower the tunnel is, the less people are predicted to circulate through. The whole Pavilion is defined with passages varying in the width, length and height. While people are circulating through the space, they can explore the different passages and the unique angular structure of this Pavilion.

Sun path, Internal structure, Privacy and threshold diagrams
From the ground plane, it shows that passages are formed in between the angular folds. These passages allow people to select different routes to either enter or walk through the pavilion. Since there are walking paths around the pavilion, people are most likely to circulate the pavilion from or towards those pathways.
The internal structures are displayed on the top diagram. Privacy within this pavilion is achieved by the organisation of the folds and thresholds. The centre part of the pavilion is the most private. From the sun path, it can be seen that the centre part recieves the least sunlight because of the overlapping folds. Also, all of the thresholds are directed towards the centre part of the pavilion which further signifies that it is the most private at the centre.
The thickness of each aluminium plane is done by extruding the surfaces. After extruding them, their points had to be moved so they donâ€™t intercept or collide with each other. Each one of them has to be done by â€œSolidPtOnâ€? then move and adjust to the right position. This goes for the internal ribs as well. Each ribs are square extrusions witth their points turned on and moved to the right positions. The placements and angle of the ribs are formed according to photographs of the interior of the pavilion. The ribs on the same aluminium plane are never parallel beacuse of the nature of the irregular angles of the folding planes. Each one of the ribs are adjusted and sits closely to the aluminium planes.
Halfway through the modelling process, it was extremely troublesome to model the internal ribs of the overlapping folds. I had to keep turning around the perspective to model one side or the other. Also, since the foldings are overlapping, turning the perspective can easily confuse which ones I was modelling at that time. On Rhino, we can adjust the transparency in the â€œDisplayâ€? tab so I lowered the transparency to 50 which made it so much easier to model complex internal structures like the ribs.
A couple of the ribs on the top plane contrains multiple ribs to intercept at one point. Although I tried to use square extrusions to then adjust them into an intercepting point, the extrusions started to deform and any adjustment on the extrusions afterwards would take a long time to process through. Therefore, for rib interceptions like this, I plotted the surfaces of the ribs with polysurface. Four surfaces for each crossing ribs which intercepts at a normal extrusion rib.
