FE E DBACK Initial project during the mid-semester review had little texture mimicry of a tree and in this final design we wanted to explore more on how our design can create a habitat integrated to the house of 12 possums as an extension of the final tree. A summary of key points needed for further refinement: 1. Mimicing the complex texture of a tree with algorithmic control 2. Controlling the density in connection to the tree branch 3. Distance parameters of the extension between the two branches. Exploring possbilities of structure with distance.

FI BRO U S H O U SE Rol a nd s no o ks This project expands from the techniques originally developed in the Fibrous Tower project in 2008, by increasing the population of strands and freeing them from the influence of a predefined surface. Unlike like latter, this project contains form emerging from its structure and articulated as a dense mas s of strands. This house has several flow of strands that wrap to enclose space and dissolve back into the landscape. Final form was created with an intentional mess, a wild assemblage that expresses its intricate internal order, without smoothing over or taming its process of formation. 1

Looking into how the strands form its own shape and creating an even more organic structure, we decided to go ahead and took the bridging form as a concept of connec ting the new iteration with the site. Using this natural behaviour of the fibers, we continued to develop the ideas that were occuring on the central and surrounding of the base structure.

Out of this total forested land, about 75% is dominated by genus Eucalyptus which is known to have over 700 species existing in Australia. Victoria is one of the states that contains vast land covered with both tall and medium open genus Eucalyptus forests. Tall and medium open forests consists of trees that are 10- 30 m high and have 30-70% foliage cover. These Eucalyptus forests of Victoria have been facing one main challenge, intense fires. These fires destroy a lot of tree species and lead to long term effects. In fact about 40% of Victoria’s forests was destroyed by wildfires between 2002-2009. The potential effects of these fires include reduction in the number of wild animals in the forests, reduction in water quality, loss of soil nutrients, soil erosion, climate change and loss of biodiversity.

Addressing on the variety of ways on how a fig can wrap itself ‘also called as the stranglerer ’ The network of roots, resembling a tangle of writhing snakes, also fuse together (anastomose) forming a massive woody envelope or “straightjacket” encircling the host. Expansion of the host trunk as it grows may accentuate the death grip and subsequent girdling process. Eventually the host tree dies of strangulation and shading, and the strangler fig stands in its place. In many cases the host tree may actually succumb from shading and root competition rather than strangulation. When strangler figs start in the ground, as in cultivation, their trunks develop from the ground upward like other “conventional” trees.

FA B R ICAT IO N The form is further developed for fabrication. From the mid semester review, we have developed five different prototypes and chose which one adheres best for the client- through digital and physical models. We began to disect these and choose a number of different explorations, as seen in the following diagrams. These were based on the critera of being as similar as possible (Biomimicry factor) to the existing branches that was on the site, through site environments and now with more precise measurements.

For the first prototype we tried to test on the plugin culebra and cocoon. We managed to create a structure that was spawn using intersecting curves to see how far we can maximise the density of the whole system. However, this first prototype had problems because given we cannot fabricate due to the uncontrollable amount of lines coming out of the structure, it was too dense for the client and does not respond for our design of sunlight. testing failed. - unfabricated prototype

Second prototype, we tried to test on how fibrous we can get as the previous prototype of fibrous tower had such intricate details that prints actually failed. The outcome was quite predictable. We liked how fibrous the base structure looked but the openings were not organic and further the process would not allow a control on the thickness of the structure.

We also 3d printed this mesh which we deemed was to thick as a fibrous material but the maximum thickness created the kind of natural opening that we liked on the dwelling.

This will provide efficiency for food gathering without having to expend energy by hunting it down. The smaller preys will be trapped from the webs into the openings of the structure, and this area is going to become the food chamber for the possum s.

OB J ECT I V ES Working individually during Part A and as part of a group during Part B and C helped me to develop the ability to formulate a brief within a digitally enabled project on conditions having never learned Grasshopper before. Through this subject, I learned thhat the key was to explore m ore than the parameters of parametric software in order to learn its capabilities, and hence develop a suitable brief which maximises the outcomes of an ideal design. Another issue raised during our project was the constructability issues of using plywood for the base and we had initially imagined on using a couple of different methods. However, after further discussion with our tutor and as a group, we decided that continuing with our explorations using 3d printing of PLA and Timber would be the best outcome.

As seen throughout the journal and the algorithmic sketchbook, I have developed the skill of generating a large quantity of iterations and design possibilities very quickly using Grasshopper. By using my newly learnt software, I have found parametric software incredibly efficient, as it has the capacity to change the entire design based on one minor parameter change.
