Week One

Reading: Zeara Polo, A. 2010. Between Ideas and Matters.

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)

Signs, symbols and icons are represent only one information. Icon has a physical resemblance between the signal and the meaning, it has directly information. Index has a correlation in space and time with its meaing. Symbol is a sign which refers to its dynamic object through a formal representation. In the sign, the relationship between form and content is arbitrary and immaterial. Diagram represent more than one type of informations, and mediate between physical constructs and concepts or percepts on organizational level, it’s an element that is not limited by logic or constraints but can bring forth new worlds.


Week One

Precedent Analysis

2 spheres and 1 ellipsoid

Insert the spheres and ellipsoid into the basic cube. -Left image: Aaires Mateus-Radix 2012 -Upper middle: Internal shape formed by three geometric objects. -Upper right: Combination of external shape and internal spatial structure. -Lower middle: The final structure shape.

Fig.1 Radix by Aries Mateus in 2012 Use ‘‘boolean difference’’ command to get the rough model. This Radix pavilion is designed by Aries Mateus in 2012, the image above suggest the basic shape and materials of this pavilion. The size of it is 8mx8mx4m, and have dome-shaped internal structure which are inspired by the shape of the docks nearby. The external surface is rough and dark, which has a sharp contrast to the smooth and bright interior. Also, the different hights of the interior space (arch) build different perception of space for people.


Week Two

Reading: Hertzberger H. 2005. The in-between and The Habitable Space Between Things, from Lessons for Students in Architecture. Herzberger discusses 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)

According to Hertzberger, “the point is to increase the ‘accommodating potential’ and make space more receptive to different situations”. He thinks design should expand the possibilities to make it more useful. If something is too functionalism, it will become inflexible. The Radix by Aries Mateus was made of cubes cut by spheres and ellipsoid, the structure was simple and allows people to explore it. The different heights of those rounded space and openings linked to the street creates threshold. Besides, the stairs under the Radix allow people to enter this structure and provide places for people to sit down.


Week Two


Isometric View of the Pavilion (SE View) I chose the South-East Isometric View to show the Radix pavilion. Radix is supported on three points and one corner is hanging over the water, and it has contrast between the dark surface and bright interior space. The shape of interior space was inspired by arch of the surrounding buildings with the culture background. Therefore, when I modelling it, I focused on the internal structure by drawing the line of the ribs. And the different heights of these arches create different experience of space for people and different degrees of intimacy, which also influenced the circulation. Besides, there is one corner of the structure hanging over the river, and consider the materials of the internal space, I think the surrounding environment is important since the smooth surface of the interior arches can reflect the water and light. Therefore, I drew the steps and water. Also, the steps near the pavilion affected the circulation, since people also gathered here and sit down on the steps. The thresholds of this pavilion provide public and private spaces with the openings, entrances.


Week Two Diagrams



There are three main entrances allowed people get into the pavilion (two roadside entrances and one waterside entrance), and people are usually gathered near the water and sit on the steps. Also the interior space with various heights affects people’s movement.

I separate it into four components: External surface, Internal surface, Internal space and the whole structure. And I divided the external surface into different parts to show the hiden surface at the back. There are three main spaces inside, from pravite to public.




Basic 8000x8000x4000 cube insert by 2 spheres and 1 ellipsoid.

In Rhino, use “boolean difference� command to get the original structure.

The bottom view of the structure. It can be seen clearly that there are three supporting points.

Appendix Process

In order to show the ribs, I drew lines at the top view and then used ‘‘project’’ command to transfer lines on these domes to show the structure underneath.

Fig.2. Use the Google Earth to find the location of this pavillion,

After identify the positon, started to build the sorrounding of this pavillion.




At the junction of two arches there is a sharp end pointing down but not touching the ground.

Perspective View in Rhino Use basic complexity of geometries to create the percaption of space.


Make2D all the images that needed and saved them in PDF. Inport images and draw lines and colour blocks for analysis. In Circulation, I inport the line of cut-through structure to make analysis clearer.

Inport images and draw lines and colour blocks for analysis. Also add dashed lines to align each image.

Adjused the thickness of the line and colour the area.
