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)

Zeara-Polo’s expression of the use of diagram and symbol within an architectural context describes that the key use and function of a symbol opposed to diagram is its ability to express the the qualities of its dynamic object whilst maintaining zero relevance between ist materiality and performance. The relationship between symbol and object remain capricious in nature whilst the role of the diagram unlike symbols, signs or icons is not required to play a “representational roll for their dynamic object and mediate between physical constructs and concepts, their performance depends on their deployment” (Zeara-Polo, Between Ideas and Maters, pg. 239).

Precedent Analysis

First Image - Wire frame perspective of ellipsoids being created in order to produce interior spaces. Second Image - Rendered Perspective of ellipsoids merged with base structure. Third Image - Upside down isometric “Ghosted� View of finished structure.

Fig. 1. Nico Saieh. Radix Aires Mateus. 2012. Through looking at images found online and provided via the UoM LMS Measurements of the Pavilion could be taken. After setting out a base structure measured 8m x 8m x 4m, the central points of each ellipsoid were determined and set out. Once establishing the location of the centre and orientation of each ellipsoid, they were created to merge with the existing structure. Once all the ellipsoids had been completed the volumes of each were subtracted from the base structure resulting in the creation of the Radix Aires Pavilion.


week Two

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 design and construction of the Radix Aires pavilion allows for the adaption of the “in-between� environment of private and public space. Whilst being completely accessible to the public the Radix Aires pavilion provides an interesting yet functional shelter that directs circulation through its form, allowing suggestion to users without dictating or demanding specific action. The varying volumes created by the inverted ellipsoid interior allows for habitual spaces within the pavilion that encourage the view and speciation of the surrounding environment.


week Two


Radix Aires Pavilion Two isometric views were chosen to exhibit the Radix Aires Pavilion. The first view, taken from the underside of the model heavily focuses on the materiality and technical paneling of the pavilion. It also clearly distinguishes where the natural light hits the pavilion and reflects to create threshold within the space. The second isometric view as taken from traditional isometric angle has greater detail in the construction of the Radix Aires Pavilion and clearly shows where surfaces meet to create intriguing geometry. This angle also more clearly distinguishes the arch heights through each section of the model. This will have a great influence on how the pavilion encourages circulation.


week Two Diagrams

This Threshold diagram attempts to focus of the spaces and volumes created by the natural use of light and the reflective surfaces of the pavilion. The first section of the diagram illustrated the paneling of the interior reflective material, and identifies the factors influencing the redirection of the surrounding natural light. The second section of the diagram singles out these reflective surfaces and looks at there physical orientation and geometry, Whist the third section of the diagram details the volumes and thresholds created by the natural light hitting the reflective surfaces of the pavilion.

The goal of this circulation diagram is to provide information around the influence of arch heights with in the structure and the effects that individual heights have on the circulation of the surrounding environment and two the space is used by visitors. The physical structure of the pavilion is demonstrated in the first section of the diagram whist the Strongest paths of circulation are demonstrated in the second section. The third section goes further and details each interior arch with their real life maximum dimensions to help explain the use of the space.

Threshold - Reflection and Volume

Circulation - Arch Heights




The initial modeling of the Radix Aires Pavilion, began with the setting out and measurement of the base structure and ellipsoid centers.

Once each part of the model had been prepared and model in rhino, i began to use “Boolean Difference” Command to subtract the volume of each ellipsoid from the base structure.

Continuing on in Rhino, I then began to draw the axis and dimensions of each ellipsoid, which i would later use to boolean difference the interior spaces within the pavilion.

As each ellipsoid was used to create a void inside the base structure, the representation of the Radix Aires Pavilion began to become apparent.

Once creating all the necessary measurements to construct the 3d model, i began to form and shape the 3D components of the rhino model. In this image you will see the 3D model in “Ghosted View”.

From the underside of the model it is clear to see the interior spaces produced through the negative space created by the cross over of the base structure and each ellipsoid.


Appendix Process

Once all the ellipsoids had been removed and only interior inverted volumes remained, the structure that is the Radix Aires Pavilion, was almost complete.

To create the second view of the Radix Aires Pavilion the model was flipped 180 degrees and recaptured from an isometric view point.

Isometric “Make 2D” lines were exported to Illustrator and used as a base of to the gently rendered final presentation.

Once flipped and view in isometric proportions, The “Make 2D” Function was used to flatten and export to illustrator.

After applying varying gradients to different aspects of the model was complete the final presentation view 1 was ready.

Once in Illustrator, the image was again flipped 180 degrees and rendered through the use of gradients to dictate when the lite and shadow hit the model in real life.
