Me Hello. My name is Janice Lobo and I am a third year architecture student at the University of Melbourne. I am of Indian orgin, but was born and raised in Dubai., UAE Both these places have a big impact on the architectural style that I am interested in. The discourse in both those cities is vastly different yet interesting because where one is an old country with a history of precedents to look to, the other is young and uninhibited by it. The difference was obvious to me as a young age and I would try to understand the cultural and technological influences behind them. Being raised in Dubai during the boom of its architectural exploration and development really inspired me to study Architecture.

The Completed I first began my digital design journey by playing around in Illustrator and Photoshop. After I took an interest in architecture, I found AutoCad and 3D Max. These were the primary platforms that I chose to work in.

Even though I enjoyed using it on a digital platform, when it came to fabrication, I was unsure about the materials that would work most effectively with my design, and I regret not going through a trial and error process to fully utilize the properties of different materials into my design instead of trying to morph them to fit my work. This semester I would be interested in looking at how materials can influence design, but particularly how parametric tools could be used to most efficently use the materials available. 2

CASE FOR INNOVATION

In Semester 2, 2011, I took Virtual Environments at the University of Melbourne. This is where I was first exposed to parametric modelling . We used Rhino to create a structure that was to interact with our body and draw influence from nature. Through this project I got to experience using parametric modelling and studied the influence it is having in the current face of architecture.

EOI: 1 CASE FOR INNOVATION

Architecture as a Discourse “Free experimentation requires less detailed constraints and computation so architects may turn to simulations with accuracy levels that reflect the stage of design.” 1

Architecture also has a big impact on the environment, built and natural. Computational tools helps us to maximize efficency of materials by exploring their contraints and working within them to create new and sustainable design. Parametric tools allows us to design in a responsible way by creating individual panels that can be taken apart and transported easily. It also allows us to generate a multitude of designs based on the constraints of site, materiality and functionality. We can use it to create responsive architecture that uses materials efficently and in new ways that are environmentally sustainable.

An ongoing discourse that is generated by recent projects such as the Burj Khalifa, Dubai, is material efficency and structural properties. As we push boundaries and create structures that are more ambitous and more innovative that the next , we generate more discourse that leads to innovation. Discovering new material properties and structural techonologies have always led to a change in architecture. When Frank Lloyd Wright designed the Edgar Kauffman House, he used concrete and steel to create massive cantelievered slabs that were not believed to be possible, but it was a success that led to other projects experiementing with these ideas. Similarly, material properties that are constantly being discovered allows us to push our designs to areas that we wouldn’t consider before. This semester we have been asked to look at the Western Gateway Project and use parametric tools create an optimum solution that reflects our area of interest.I would like to explore the materiality through strips and folding to help me achieve this goal.

CASE FOR INNOVATION

Architecture is so embedded into our lives that we sometimes fail to see the effect it has on us. The creation and manipulation of space can inform our emotions, productivity and well-being. For example, an open plan space can prove to be more effective in some office environments in comparison to individual cubicle layout and hence increase productivity. Therefore it is important that architects take responsibility for the responses their designs evoke in people.

Trada Pavillion, 2013

Exploring Timber Timber is a material that is usually used for frames and straight line structures. Due to its inefficency under tension, and its tendancy to warp and twist with changing weather conditions, it is not always the most ideal material to use for curved and organic shapes. But timber is a light weight, organic and renewable material. It creates an emotional response of warmth and can be designed to be fluid structures in nature. Parametric modelling can be used to to explore the possibilities of timber further. Curved structures can be panellized into flat volumes that can be easily laser cut and attached together using a large number of joining systems. These systems are lightweight and have to be joined at the ground. The Trada Pavilion designed by Ramboll Computational Design that is scheduled to be built for at the Ecobuild Exposition 2013. The structure used an algorithm to divide the structure into planar three-valence mesh that can be constructed using flat panels. The advantage of using a hexagonal mesh is that it has greater structural efficencies and requires fewer connections. The panels are 15 mm thick and were fabricated using a three-axis CNC route 2. The fabrication process included the drilling of holes for hinges, bolts and cutting the contours for the panels. Grasshopper was used to place the hinges in optimum locations 3.

CASE FOR INNOVATION

The pavilion uses ordinary flat timber panels and hinges, combined with an algorithm that provides the information required to design a free standing timber structure. This idea is can be easily applied in design temporary shelters quickly and efficently in disaster zones. The showcase of this structure in an event such as Ecobuild generates discourse and allows this building technology to be studied and publicized.

ICD/ITKE Research Pavilion 2011

Like the Trada Pavilion, this structure is light weight, made of a sustinable material and easy to construct. It creates a shelter space the evokes emotion through its repeated pattern and overall aesthetic. The cocoon like shape gives a feeling of protection, gowever it also shades from the views of the environment. This is compensated for by the large openings at the end which create a dramatic outlook. These ideas would be useful to the Wyndham project because they would help convey an emotion to the travellers. Because the moment is so brief and fleeting, we would need to encapsulate the drama that this structure has with an ease of construction.

CASE FOR INNOVATION

Similarly, the ICD/ITKE Research Pavilion at the University of Stuttgart uses computer based design and computer manufacturing methods to create an ideal structure using complex geometry derived from bionic principles of a sea urchinâ&#x20AC;&#x2122;s plate skeleton. The structure is built out of thin sheets of plywood measuring 6.5 mm, fastened to the ground to prevent it flying away due to this extremely light weight. The joinery used in this structure was also derived from nature. Computational design tools were required in this project to derive the complex repeatiting geometry, where the hexagons change is size depending on what is most struturally viable and the local curvature. This structure also has the advantage for being able to take it apart and transport 4.

Computerization in Design

“design computation is still only seen by many as ‘just a tool’ and remote from the real business of creative design” 5 Computerization plays an important role in responsive architecture. In the Al Bahar Tower designed by Aedas Architects, the skin of the building is a shading system that responds to the sun. The shades open and close to let in sunlight and provide privacy. It is designed for the hot UAE sun, so the entire skin moves along with the sun to shade different parts of the building during different times of the day. Even though this may seem inefficent and expensive, the shading system is expected to reduce the buildings requirement for air conditioning by 50%. This positive environmental effect is something we can hope to achieve through the use of computational tools that would be must more difficult, or even impossible to create without.

The form of the shading system is called a mashrabiya which is an Islamic shading system. Using this as an inspiration, the design was computed into a digital modelling software instead of computerized which is the creation of design in a modelling software. In this scenario, the benefits of the computed system, allowed the designers to panelize the facade in a way that can be morphed - moved, opened, closed - to respond to the environmental conditions. However the layout of entire skin and the forms it creates as it moves across the building was determined by computerization 6. This project is a combination of both computerization and computation, and is an embodiment of the idea that computer aided design leads to structures that combine aesthetics and functionality. This structure is almost fits into Louis Sullivans idea of form following function.

CASE FOR INNOVATION

Al Bahar Towers, 2012

The ContemPlay Pavillion is based on the principle of a three dimensional Mรถbius strip supported by a triangular truss. Digital modelling was used in this pavillian to ensure that the individual tubes do not intersect with each other 7. They use digital modelling to vary the thickness of the tubes. Grasshopper was able to predict every connection and joint accurately depending on the thickness of the structural members 8. In this way, computerization has enabled the designer to explore possibilities that would have been near impossible to do otherwise. It has opened up the possiblities for creation instead of taking away the creativity. Using Grasshopper, the team was able to change the variables in the structure, giving them control of the outcome. Digital software also helped bridge the cap between engineering and architecture. Engineering computational software was used to realize the stress of compression and tension that the structure would undergo and the information derived from this was inputed into Grasshopper that checked that there were no interferences with structural changes made. Computation has allowed for a platform and language that can be read across various professionals.

C o n t e m P L AY , 2012

The ContemPlay pavilion was designed and constructed by Masters of Architecture students at the University of Mcgill. Their study into parametric modelling allowed them to build a structure of this scale and effect.

CASE FOR INNOVATION

It must be noted however, that if one is unaware of digital modelling software, it would be much harder to read and understand the programming code than hand-drawn plans. But the advantages of using these softwares in a professional environment by trained designers is leading to a new wave of architecture that is only possible because of it.

Parametric Structures Computerization can be used to predict environmental patterns.It can also be used to predict the ways in which a space will respond to the environment depending on its wall thickness, height, etc. By treating the optimum environmental condition as a constraint in your design, you can use parametric tools to create a solution.

Housing Competition, 2007

This housing proposal in Oman utilizes a rhomboid framework within two strips to produce the model. The surfaces’ length, width and thickness is responsive to weather conditions, thickening up in high temperatures and moving the panels to allow for increased ventilation indoors 9.

This project requires a sophistacted amount of control and it attempts to manipulate a very harst environment into become habitable and comfortable. It attemots to preserve the lical ideantity and image, while still being innovative. The use of parametric tools allows us to set boundaries and constraints for the structure. It allows us to create a multitude of parts that can easily be sent to a local laser cutter to create stones of the extra shape and heigh. Because of the smooth nature of the form, the precision is very imporanr here Using Parametric tools, has allowed them to also control the light and shadow patterns and let the design be changed and influenced by this. In Wyndham, this is what our structure would do as well. It would constantly change, so that the way ts users interact with it can also be a changing experience.

CASE FOR INNOVATION

Parametric modelling allowing for the constant change in form through out the design process.

Bengbu Opera Music Hall

Parametric modelling can be used to create efficent structures have increased material efficency. The basic structual system usied in the Bengbu City Opera/Music Hall is a gridshell. The quadrilateral grid is comprised of steel tubes and stiffened by steel rods to maintain the systems stability. Using parametric tools, they were able to optimize the curvature of the gridshell to minimize the curvature of glass panels that are expensive to fabricate 10. This project utilizes the strength of steel as an informant for the design itself. The material performance of both steel and glass act as parameters allowing for various possibilities within their constraints. The exterior concrete shell is proposed to be constructed using a steel frame with lightweight concrete precast concrete panels on the outside and acoustical panels hung from the interior of the frame. This would reduce construction time and avoid extremely large loads that would be created from a monolithical approach.

Indigo Deli, 2011

sp+arch are focused on challenging the existing discourse, particularly through changing the socioeconomic typologies. They used parametric modelling for their design Indigo Deli in Mumbai13. One of the parameters that had to be worked within was the brand image of this chain restaurant. The client wanted to maintain the aesthetic feel of the restaurant and insisted on using copper and timber elements14.

Parametric modeling was used here to create the three dimensional space for a restaurant. This discourse around this structure is that it symbolizes the retail culture and the trappings of the mall context. It was constructed using steel rods, fixed to plywood panels that allowed the leveling of the framework. The panels do not act purely as a roof covering and decorative element, it also merges into the ground creating a shelving system that can be easily used by the behind-the-counter staff.

CASE FOR INNOVATION

It is a hybrid structure that uses the combination of structural elements such as quasi-dome and quasi-structure to maximize the structural efficency within the constraints of the layout. The architects use intersecting strips of timber that have been solved in using parametric modelling softwares13.

ZA11 Pavillion, 2011 ZA11 Pavillion designed by students for the ZA11 Speaking Architecture event in Cluj, Romania. The purpose of the design was to attract people to the architecture festival as well as providing an interactive space that could also function as a shelter. The major constraints of the design was the budget and fabrication techniques. Parametric modelling tools were helpful in this aspect because it allowed for the logical labelling of individual strips that could be put together on site 11. The students used Grasshopper to create the individual panel strips that were divided into 746 unique hexagonal pieces. The panels were of varying thickness to reduce and increase loads in required areas. In this case, timber proved to be a viable lightweight material that allowed the construction process to take place without the use of heavy vehicles 11. This project is interesting because it uses simple manufacturing and construction techniques and an amature knowledge of parametric modelling tools, but is still a successful temporary structure that functioned as a pavillion space during the festival. This contrasts Woodbury’s theory that parametric tools in that hands of amatuer uses leads to amateur design because the software controls the user 12, but in this case, proved to be the other way around. 11.

For this course we are to use Grasshopper in Rhino for our Gateway design project. Following the weekly tutorials, I have chosen these 3 experiments because they are most relavent to my field of interest, even if they are not the most successful. Fig. 1 uses point attractors on delaunay mesh surface to create a series of cylinder of varying heights and diameters. This approach would be useful in creating my major assignment because it would enable my group to vary strips of thicknessâ&#x20AC;&#x2122; and widths at points for either aesthetic value or structural and material value.

Fig. 3 also works on the framework of a series of curves. It uses a conditional statement that offsets theres curves based on the length of the curves and forms a triangulated delauney mesh that is derived from the geometry of the initial loft and the offsetted loft. This experiment was based on the ContemPlay design, one tha I would like to further explore using additional plugins such as Kangaroo.

CASE FOR INNOVATION

Fig. 2 extracts the edges of a delaunay mesh and converts them into individual planar quadrilateral meshes that follow the form of the initial curve. This method would be valuable in creating individual panels that can be divided into easily fabricated panels.

Conclusion

My design approach will utilize material properties as constraints for my design, and by this, expanding the possibilities in which the material can be used, as can be observed in the Trada Pavillion and ContemPlay, where the designers used the material strengths and weakness as constraints to create new and innovative designs. My approach will also be framed by exploring strips and folding methods such as the Mobius strip. It is significant to design in this way because it uses the knowledge of exisisting material properties and geometries to create a new and innovative structure that push the boundaries of the basic elements of the structure itself.

Learning Outcomes

I have always had an appreciation for computers as a design tool. This course taught us that are merely tools in the designers hands, the same way a pencil works as a tool and therefore does not control the design, merely guides it and helps to provide new outcomes. However learning about parametric modelling has changed my outlook towards designing. It has allowed my to realize that the computer can also be used to solve problems and force us to design within constraints which would cause us to push our creativity within possibilities instead of designing creative wonders that our impossible to construct and leading us to compromise further on in the design process and ending up with designs that are much less successful. By setting up the limits initially we can design structures that can be easily constructed and maximize time and material efficency.

CASE FOR INNOVATION

This design approach would have been useful in past projects because it would allow me to make changes further on in my design process without affecting the overall constructibility of my model and drawings.

EOI: 2 DESIGN APPROACH

For the Western Gateway Project, we were put into teams with a particular research focus. My team will tackle this project from the perspective on Strips and Folding. However within the parameters of that topic, we have broken it down further to allow us to each focus on our own individual ideas and then bring them together to form a cohesive whole. This idea was derived from our understanding of how architectural practices work, and delegating the work, as well as inspired by the design process of a previously mentioned project, the ContemPlay Pavilion. In the ContemPlay Pavilion project they split the work into general aesthetic/design, structure, details and materials constraints. We thought a similar approach would function well for us, and the area I was assigned was material constraints. I went about this by conducting research on precedents, and through a process of fabrication with different materials. Using Computational software I attempted to generate a natural environment in Grasshopper to test the performance of materials under specific conditions such as the changing sunlight and wind.

DESIGN APPROACH

I believe this holistic view is ideal for Wyndham to take to best respresent its city and create to generate a discourse about the place and ideals associated with it.

ICD/ITKE Research Pavilion 2010

Design Focus

This pavilion was designed and constructed by the Institute for Computational Design (ICD) and the Institute of Building Structures and Structural Design (ITKE). The structure aimed to portray recent developments in computational design in regards to material performance and new processes in fabrication. The structure is a system of very thin, bent plywood strips.

Using computer software in combination with fabrication, they tested the bending properties of different types of timber. Even though we do not have the se sofisticated tools available to us, we can visually observe the materials and try to generate the closest effect possible. 13. Menges, Achim. â&#x20AC;&#x153;ICD/ITKE Research Pavilion 2010â&#x20AC;? 2010. University of Stuttgart. Accessed 06 May 2013. <http://icd.uni-stuttgart.de/?p=4458 >

DESIGN APPROACH

This project is innovative and relevant because is demonstrates a new approach to design. It emphasises the importance of considering materials properties as they are always a factor in built projects. In my Case for Innovation, I explored the new kinds of design and forward thinking approaches that result from considering material properties. This pavilion is an example of that aprroach. The design of the structure is driven by the performance of the materials - in this case, the elasticity of plywood strups. These strips are manufactured robitically and connected to allow for tension along their length. It was key to use computer software in this structure because depending on the stresses, the strips and joints were changed resulting in 500 geometrically unique parts. This approach however allowed for a very lightweight system that is constructed from 6.5 mm thin birch plywood strips.

Moire Effect The moire effect occurs when two sets of gridlines are overlaid on each other. It creates an illusion of depth and movement across the surface. By incorporating this into a method of strips that our overlaid, we can create a smooth and calming effect.

DESIGN APPROACH

The Moire effect created here is in the facade of the building. It adds a level of dynamism to the structure. An interesting point about this building is that it is windowless. There are verticle black stripes painted onto the facade, and then aluminium slats added over the top. This has allowed it to create different interference patterns as you move around the buiding. It also means that the moire is independant of light and shadow, but engrained into the structure.

Case Study 1.0 Biothing Pavilion This project was good to explore because it was comprised of individual strips that could be changed. I experimented by changing the length of the strip, the Fline number, manipulating the nth strips in size and warping the entire surface around another shape. These particular influences were chosen for a reason. The strip elongation was to play around with the form to achieve an interesting result that would suit the material properties of timbe - a material that I desire to construct my project out of because of flexible properties, performance in tension and sustainable source of material. I found 3 and 4 to be too short and therefore the stress no distributed properly, 1 and 6 to be too long, required much more material that would make the structure heavy. Iterations 2 and 5 were most pleasing, however I would choose iteration 2 purely because of its orientation. The second test was to change the Fline number. This changed the overall size of the instances. The higher the number, the greater the size. Number 5 would be more interesting as it would for long strips that could act as a shelter and still be self supporting. The third test was to change every second strip to be a horizontal straight plane. This would create a dynamic effect and allow for every odd member to be utlilized for another purpose, structural or aesthetic. It also allows you to play with the length of those strips independant of the others. I felt that all the iterations were successful in their own way, but number 3 offers potential to use the alternate strips for other purposes and generate a more complex lighting pattern. The fouth test is interesting because it allows us to change the form of the pavilion as a whole. Using the pull curve function, we could generate the natural environment and pull the curves to fit within it and even mirror thegeometries.

Case Study 2.0

To begin our design process we reverse engineered an exisiting project in Grasshopper. The project my group chose was the previously mentioned ContemPlay Pavilion. We chose this project because it related back to our Case for Innovation. The project is a Mobius strip - which is a strip with one continous edge that runs along the entire shape. We created the strip using LunchBox. This overall shape is divided into equal strips, various methods of generating surface divisions were attempted but we decided to go with the one that would best lead us into the next stage of the design. The third step was extrating individual panels from the strips. The final stage was creating the second layer to acheive the Moire effect. This project influenced a concept for a our design. We decided to explore the Moire effect further after the successful tests acheieved here. In terms of the materia

Step 1: Mobius Strip

Step 2: Dividing into strips

Step 3: Creating panels

DESIGN APPROACH

Step 4: Creating a second layer and rotating it to create moire effect

Intial Explorations - We first tried to play around with the mobius strip, but dividing it up in different ways. Each iteration also led us to think about material. The ones we considered we metal, stone and brick, based on the shape we were getting. However we d ecided that we wanted a more lightweight structure , and more importantly, one that creates the moire effect, and it would therefore have to be long vertical strips.

We then tried to add a wind element to the structure and hoped to derive a form from that. Even though this produced interesting effects, we couldnt mimic the stiff joints and overall structure that we wanted to. We decided that future wind experiments would be conducted once fabricated.

In our form finding process, we came across an idea of keeping the sides enclosed and opening the skies up. We experimented with an elongated strip form to generate this idea.

However we decided that this form was not idea for therefore needed to do more research and form

us, and finding.

DESIGN APPROACH

Strips - We then latched on to an idea of a bird taking flight, and using the form we derived from this idea, we attempted to use different methods of generating strips. We found the final version to be most effective in generating the effect we would like to create.

Transition Transition through Form The concept we developed is the idea of Transistion. Looking at the history of Wyndham and the values they are trying to create in the community. To passively delivery this message into the travellers mind we looked at forms that express this idea through the idea of transistion. Sagrada Familia by Gaudi contains a series of helicoid shaped stairs. He uses the sinosoidal curve to represent the transistion between spaces. We intended on using this analogy to create a continous transistion of space. The representation over a long area, combined with the moire effect that we intend on creating, will help deliver our message. That Wyndham has its own values of sustainable development and a strong sense of community focus . Transition through Material Timber Timber is a light weight sustainable material. It has an aesthetic of warmth and the natural. We feel like it is a material that could appropriately be used to describe Wyndham. Therefore we decided that the side of the structure facing Wyndham would be constructed out of timber. Metal We want to represent the city as a place of industry and technology. It is a place of innovation. We don’t just want to create an excitement about Wyndham, but an excitement about moving through - transitioning - through these spaces and seeing the benefits of both. Therefore we decided to use metal on the side facing the city.

14. Sagrada Familia. “HELICOIDS AND CONOIDS ”, Accessed 05 May 2013. < http://www.sagradafamilia.cat/sf-eng/docs_instit/geometria5.php >

Helicoid We created the helicoid shape using the Lunchbox tool in Grasshopper. We then applied the same paneling information that we had to the mobius. We experimented with different panel widths, number of panels, and changing the widths at particular areas in the structure to achieve particular effects. We attempted to copy the double layered mobius strip seen in ContemPlay with the helicoid, but found it to be loud and distracting from the similicity of our idea. However this meant we needed a new way to achieve the moire effect.

We experimented with turning the panels to the direction of the sun. This allowed us to experiment with different shadows created on the ground and change the direction of the moire effect was. Even though this experiment produced interesting individual results, it meant that the structure would only really be effective at a certain point in the day, and therefore we decided to go with the original helicoid structure. 34

DESIGN APPROACH

We experimented by applying wind through this structure as well. Similar to the other wind experiments, the entire structure was subject to it, like it was made out of paper. This struck a temporary idea to move in the direction of a folded structure that moves and bends with the wind. But our initial concept took over.

Technique Development

We found that the solution around creating the desired effect throughout the day was in rotating the position of the structure on the site so it sits at a diagonal. This would mean that at particular points along the drive, the user would see a moire effect. This creates a dynamic element to the design, as well as opens it up for discourse . We also decided to use a double helicoid, but instead of layering one behind the other, we decided to inverse them, creating a long contious flow. Through fabrication process we also realized that there is an interference pattern created on the ground that the users would drive through. This would create a passive relaxing effect. The individual panels would be constructed out to timber with each instance being an alternating material. The elements that are constructed out of timber would, by the nature of its material properties, be more flexible than the metal ones. We would create movement joints to allow the top portion of the timber to sway, but keep the metal steady and constant. This would represent a changing and dynamic Wyndham community.

DESIGN APPROACH

We believe that this movement would also localize the structure more. It would use the winds on site to produce an effect that would be unique to the site. On an open freeway, the change in materials would also instinctively let its users know where they are headed to.

Prototypes

We chose to conceal the structure by cantelievering the columns from the ground. We required a stronger ground for this. In order to get the angle of the columns correct, we came up with a double ground system, where would would create two ground levels with slits for the columns. Therefore the columns would automatically adjust itself to the correct angle. This method proved to be very effective, however we are not sure of its success when we apply thicker materials.

Initial Prototypes

DESIGN APPROACH

Final Prototypes

Technique Proposal

In designing this Wyndham structure we have always kept in mind that we are designing for Wyndham. The timber obtained will be locally sourced, to enrich the representation of Wyndham. We achieve this representation by elongating the sculpture to fit the entire site, creating significant time period where the user will experience the juxtaposition between the Wyndham community and the city. The contrasting materials act as an agressive method of making the users aware of the place, but the more subtle moire effect that the would drive through would passively relax their sense. The tapering of the materials towards to respective side that they face act as arrows pointing the users in the direction of their transisiton.

DESIGN APPROACH

Further improvement we are looking at making is considering the experience of the sculpture at night; possibly by incorporating light, implementing a sustainable construction technique when considering the manufacturing of the panels in order to address Wyndhamâ&#x20AC;&#x2122;s sustainable and environmentally ideals and improvising on the rudimentary movement joints that we have design at the moment to acheive a motion that is gentle and effective.

Algorithmic Sketches

We were suprised at how much the computational tools used informed our design approach. Linking this back to my Case for Innovation where I discussed how the software is a tool that facilitates our design and creates new outcomes, Grasshopper and the plugins we used in it allowed us to make design choices that we would not have before. The tools provided to use through the tutorials allowed us to consider different panelling systems, even through we chose to go with a basic stripped and divided form. We were able to apply real life conditions like sun and wind to test different effects that could be created through the natural environment. We were easily able to generate a helicoid form through the use of lunchbox, and this made us more inclined to test this shape that could have otherwise be an obstacle we would not have attempted to cross.

DESIGN APPROACH

I would say that designing algorithmically is the reason our design process has ended up in this area.

Learning Objectives The feedback receieved during the presentation directed us in the direction of exploring the relationship of the structure to the site further. Unsure about how to approach this, we decided to look at the Wyndham area further. We decided that we need to change our method of construction. Currently our structure is comprised of unique members that would all need to be manufactured individually. This differs from the ideal sustainable solution that Wyndham is hoping to present. We considering standardising our members, however this would loose the exisisting effect. We also considered creating frames and using a claddings system, but that would involve unrequired materials and complications. We are still in the process of coming up with the ideal solution, and hopefully by putting our heads together we will have one.

Using the tutorials on Grasshopper and Kangaroo provided to us in the course has been paramount in my understanding. I used it mainly as an outline or a referal when I got stuck in my design process instead of designing as I went along the videos. I felt that if I were to do that, my outcome would be identical to that of my peers, therefore I did not view the videos in a linear fashion, instead bounced around based on the stage of my design. A change I would like to make is to revisit the tutorials on data structures. Even though my grasp on Kangaroo Physics is better now, I still feel lacking in my understanding of the way the algothrim views that data, and a better understanding of this, would lead to a better design outcome. The most important lesson I learn however was the importance of fabrication. The next stages of our design will include a much larger amount of fabricated models, tests for materials properties and structural issues to inform where our design goes next.

DESIGN APPROACH

The theortical approach of studying precendents and understanding the way in which they used computational tools has been very useful in our design process. We have also attempted to use these tools to create and try methods that we wouldnâ&#x20AC;&#x2122;t have manually. This has taken our design further and made it more holistic.
