BRIEF 01: Abstraction. Section 1. Weaving Explorations
This section focuses on the initial research into plywood, weaving patterns and techniques and their impact on the behaviour of plywood strips.
DS10
Introduction
The introduction of Brief 01: Abstraction and Design Statement.
BRIEF 01: ABSTRACTION WOOD
Students will be creating a large scale wooden structure. The material wood can take many forms from lumber, plywood, paper, pulp, bamboo etc. We want you to choose one and to explore the extremes of its potential through undertaking and documenting material research through both physical and digital explorations of the material.
SYMMETRY
In parallel, students will explore symmetry in Mathematics, Physics, Nature and Architecture. Students will be given fundamental lessons in Rhino, Grasshopper and Maxwell and using these digital tools will explore the role of symmetry in the natural world and in architecture, exploring its potential as a tool to grow, unfold and “bloom� complex novel geometries.
OUTPUT
Students will be expected to build large scale wood prototypical models exploring symmetry which should be modular, cost effective, transportable and beautiful. We also expect blog posts on WeWantToLearn.net to share your research and a working portfolio.
WHAT The project aspires to look into creating seamless symmetric architecture using weaving techniques combined with bending of plywood strips. Inspired by Hanakago - Art of Japanese Basketry and woven structures by Honda Syoryu, it looks into creating a sense of fluidity between architectural elements such as windows and walls by flowing between open, porous and closed. The project also investigates the impact of bend-active forces onto thin plywood strips and its relation to structural strength of the produced modules.
WHY Being fascinated by natural systems, the fluidity and consistency within them, I have always looked for that in architecture. Therefore the opportunity to create a system that would learn from those systems and present a seamless skin that is closed and open where needs to be - like a human skin - seemed perfectly suited to my interests. Weaving techniques showed me how you can smoothly connect small pieces and create a flexible, consistent structure with a lot of architectural potential and I have decided to focus on developing this approach as part of my response to Brief 01.
Agata Korzeniewska
TWISTED PELLUCIDITY
As natural systems not only look beautiful but also work in the most efficient manner, I became fascinated by using bend-active forces on the thin piece of plywood to give it structural strength that it otherwise lacks. Those experiments led to me discovering a module that was approximately 10 times stronger than the original plywood strips it was made of - thanks to bend-active qualities of plywood and a number of torsional forces acting against each other. Both bending experiments and weaving techniques combined allowed me to reach my goal and come up with a seamless structure that is both open and closed, providing privacy and a breathable skin at the same time.

The Japanese woven baskets and sculptures all had the same fluid yet intricate character which inspired me to explore weaving techniques and this craft further.

These examples show that weaving is used as an architectural technique mostly within South-East Asia and with use of bamboo. They prove that it is a viable approach to sustainable large scale structures, especially in hot climates.

Pattern 02_Square Plaiting
Pattern 03_Twill Plaiting
Pattern 04_Hexagonal Plaiting
Pattern 05_Hemp Leaf Plaiting
Pattern 06_Compound Lozenge Plaiting
Step 01_ Square grid of points
Step 02_Points separated into weaving lines
Step 03_Points separated within their lines
Step 04_Every other point moved up within every other vertical line
Step 05_Every other point moved up within the remaining vertical lines

Step 07_ Points moved alternately within horizontal lines
Step 08_Vertical lines interpolated through moved points
Step 09_Surfaces lofted alongside interpolated lines to imitate wooden strips
The most basic plaiting pattern commonly used in basketry techniques. The strips of the pattern are spaced closely with an emphasis of the horizontal elements what gives it its character.

Plaiting pattern based on an arrangement of hexagonal cells, each formed individually out of 6 strips. It is commonly used as part of decorative walls and flower baskets.
Type of mat plaiting characterised by balanced horizontal and vertical elements creating square openings between elements. It is commonly used for bases or walls of baskets.
Type of triangular plaiting which incorporates 3 extra strips into a basic hexagonal plaiting. Leaving the hexagonal cell in the centre and then plaiting in 6 directions results in a pattern known as ‘hemp leaf’.
Plaiting based on overlapping the strips in one direction over multiple ones perpendicular to it. Typically it is a variation of a mat plaiting in a double configuration however other types differ the number of strips.
Type of square plaiting oriented diagonally with added vertical and horizontal elements. It shows particularly strong structural rigidity which is why it is often employed in the walls of many baskets.

Weaving Patterns
Agata Korzeniewska
Testing the flexibility and curving behaviour of different plaiting patterns showed that some of them are easier to bend and curve further, some generating almost a cylinder without any extra effort. On the other hand, some showed higher resistance - the compound lozenge plaiting was particularly structurally strong whilst simpler patterns such as square or twill were much easier to mold. The experiment also proved that plaited surfaces curved differently depending whether horizontal or vertical members were followed and seemed to be most likely to create a closed cylinder when approached diagonally to the members. The hexagonal plaiting pattern was particularly interesting as it showed strong resistance when bent along its horizontal members whilst creating tight cylinders when bent the other way.

The Carolina Star was the first attempt of merging weaving with bending plywood. For that reason, the bent corners became of particular interest to me as they were very versatile and opened a new area of research. By moving the top weave higher one could create different amount of volumetric space in the middle - a feature that showed potential in terms of the formation of pod-like living spaces in the future. However interesting volumetrically, the corners of the star were the weak part of the whole object. Because of lack of tensional stability holding it in place they allowed a large amount of movement and meant that the structure could only be rested on the woven parts. Because of this I decided to investigate only this corner and try to find a way of making it structurally strong so the structure wouldn’t be limited to resting on its middle.

Conclusion_ Even though the distribution of the uniformly rotated vectors throughout the whole strip alongside with anchoring both of the ends results in bending similar in plan to the physical behaviour, it prevents the strip from twisting - therefore the simulation does not achieve the desired result.

Conclusion_ Although the simulation did result in bending and twisting a strip of wood the twist appears in locations that don’t truly correspond with the physical tests. Anchoring of both ends of the strip also prevents
the end of the strip to move as it does whilst twisting the strip in real life.

Conclusion_ The simulation shows that for it to be representative of the physical test, the bending and twisting forces need to be accompanied by the pulling force which will work against those pulling it close to one
end of the strip and will try to keep it close to its original position.

The System as a Field Condition Stan Allen, From Object to Field.
S.ALLEN, FROM OBJECT TO FIELD: FIELD CONDITIONS IN ARCHITECTURE AND URBANISM
In his text From Object to Field, Stan Allen explains the idea of a field condition in architecture and urbanism by a very articulated approach to heterogeneous space in architecture. It talks about looking for a smooth design whilst accepting the unexpected reality of design. He bases his approach on creating a form through a sequence of events where time and process play a crucial role. Rather than creating a finished form, he argues architecture needs to be able to adapt and grow according to the needs of the users and suggest a system that grows - by starting from a local element and defining its connection to the next one, the final form becomes simply the result of this action.

TWISTED PELLUCIDITY
Field Condition is any formal or spatial matrix capable of unifying diverse elements while respecting the identity of each. That leads to the overall shape and extent being highly fluid and less important than the internal relationships of parts which determine the behaviour of the field. In this case modules can be added infinitely with the remaining texture woven in between creating a dynamic field condition and creating an architectural design by starting from the individual element, letting it grow incrementally and defining how it connects to the next one.

Final Proposal. Variations.
The final proposal learns from the systemâ&#x20AC;&#x2122;s structural strength and brings the fluidity of it to a different level. The variation between open and closed allows to create what feels like a house - with woven part working as the walls and roof and twisted module part as the breathable parts such as windows. It also allows the possibility of creating a courtyard typology by allowing people to enter the middle column. The proposal shows a lot of potential for sustainable living in hot climates using only one, widely available material and providing a consistent and smart structure that uses the bend-active forces of the module to keep it in place.

15 sheets of 1.5mm thick ply were cut down in batch to 25mm wide strips using a wall saw thanks to assistance of Ed Lancaster, one of FabLab technicians. This allowed for a fast production of 720 strips which otherwise would take a long time to cut. The strips were cut alongside the shorter grain what made them bend more. Trying to produce the same module I have tested before I attempted to create the same one using longer strips. However, I found that the strips cut against shorter grain - so technically more likely to bend - had a much lower resistance to the torsional force I have been putting on it. As a result a number of strips broke into half and the only way to force the desired curvature was to fix it in 2 places along its path - something that was not necessary before. This meant that it was impossible for the twisted strips to push against each other which has completely changed the structural properties of the entire piece. This exercise taught me a crucial lesson of the importance of cutting plywood with the correct grain to allow tested bend-active forces to strengthen the piece.

Photo 08_ Large module as seen from the side.
Due mostly to the strips being cut against a different grain that those previously tested, the module lost its unique structural properties. Instead of being naturally tense thanks to the bend-active forces acting against each other it became flimsy and loose. It allowed a large amount of movement and effectively as a module became structurally weak. In order to make it work the wood needs to be cut against the longer grain but even then it would require further experiments in regards to the appropriate width and thickness of the pieces of this length for the module to work as intended. Unfortunately there was no more time to do this before the final built.

Following the failure of longer 1.5mm thick strips I have decided to amend the design to use the material I have sufficiently tested - 25mm wide 600mm long 0.8mm thick plywood strips. That however meant that I required twice the amount of module sets in comparison to the original assumption. The production of the modules was rather intricate and took 30mins per 2 modules connected to each other.

After having prepared all sets of the modules, I have continued to fabricate a set of textures following the same rules as those of the column. First it was important to attach strips as an extension of the top of the module and weave them with each other - each of those took approximately 3h. Afterwards I have attached the remaining sets of modules and filled in the gaps created by the rotating and growing character of the woven surface adding 6 modules per each of the textures. This process was very rigorous, intricate and time-consuming however it has created rather impressive results.

Photo 01_ Lifting of the texture with help of my brother, Jakub.
Unfortunately it turned out that the final texture of the desired size was too heavy and too flimsy to stand up. Even though the modules add significant structural stability to the plywood making the 0.8mm ply capable of holding weights much bigger than it would otherwise, this exercise showed me that we reached the limits of its strength capability. This resulted in a woven surface too heavy to hold its own weight and therefore not able to create a pure geometry - the only one that would allow it to stand freely. This could have been prevented by placing the structure on a base that would effectively clamp it into place and force it to create a circle allowing for even distribution of weight and giving it stability. Another affecting factor was the thickness of the ply - texture in the middle was made out of 1.5mm when the modules only used 0.8mm thick plywood strips. This made the middle significantly heavier and put even more force onto the bottom set of modules. Further tests into creating modules of equal structural stability but thicker and longer strips are necessary to find the limits of the free standing capabilities of this structure - those that were unfortunately exceeded this time.

The System: Construction Process Final Model.
CONCLUSION Thanks to this process I have learnt a number of new things about my system and thin plywood as well as about all the elements of production that I was not aware of before. The material arriving on the 9th of January made it a massive push as for that reason I was unable to test the system on one sheet - this resulted in large module not performing like the previously tested one what could have been avoided had the material arrived earlier. The problems also created by the set of rivets not arriving at all meant I had to find an emergency supply of an equivalent fixing - something that was an unexpected change of plans. This model showed me what are the limitations of my module when made out of 600mm x 25mm x 0.8mm plywood strips. It has proven to be still incredibly strong for the thickness of material however it seems that 1m diameter is the largest for the structure to stand up.

WHAT
Students need to consider the resources needed for the community to grow and sustain. What makes it a sustainable community? How does the community flourish and survive?
OUTPUT
Students will be expected to produce an extensive portfolio explaining their proposal for the sustainable community using high quality renderings, clear diagrams and other means needed to describe the project.
PALM OIL
WHAT The project addresses the problem of deforestation on Indonesian Borneo caused by growing number of palm oil plantations which became a main economic driver of the country. It proposes cutting down existing palm oil plantations, using felled trees to create plywood and eventually weave the Twisted Pellucidity Village. Thanks to highly developed basketry craftsmanship within discussed area, the previous oil palm farmers will be taught by an NGO how to make a Twisted Pellucidity column and then tower basing their knowledge on the basketry. Following the example of Costa Rica, ecotourism will become the main economic driver replacing palm oil production. With help of ecotourist - volunteers the community will participate in reforestation projects, aiming to bring back the tropical rainforest on Borneo to its previous size.
Currently palm oil plantations are the main reason of deforestation in Kalimantan destroying 498 000 Ha/year of tropical rainforest.
HABITAT RESTORATION BALANCED ECOSYSTEM HEALTHIER PLANET
WHY Nowadays, we are loosing invaluable habitats all around the world on a daily basis. Tropical Rainforests contribute to cleaning our air, holding in CO2 and producing oxygen needed for all species living on Earth. Currently palm oil plantations lead to a total destruction of rainforests on Borneo - and those are particularly rich in endemic species of both plant and animals. They also deprive many animals from their habitats slowly driving them into extinction.

Case Study: Costa Rica - A 21st Century Environmental Leader
Using Costa Rican environmental business model as a parallel for Bornean Indonesia. Costa Rica is one of the leading countries when discussing environmental policies. In 2015 it has pledged to become carbon neutral by 2021. With many sources of renewable energy, Costa Rica gains its power from hydroplants (78%), wind and geothermal energy (10%) and biomass and solar energy (2%). It set records in the most consecutive days of using solely renewable energy making it 300 in 2018. Costa Rica is also a leader in reforestation and ecotourism programmes, bringing scientists, students, volunteers and all nature-lovers from all around the world to help make the Costa Rican biodiversity flourish.

1986 21% Forest cover
Reforestation Before the World War II, 75% percent of Costa Rica’s territory was covered by tropical rainforest. In just a couple of decades this percentage dropped to dramatic 21% resulting in a tragic losses in biodiversity. In late 1980s Costa Rican government realised the value of its natural wonders and started the very many reforestation programmes. Through tree planting using various methods and conservation programmes the country managed to regrow its tropical forests which already in 2012 covered 52% of the country. It is one of the most successful examples of reforestation projects in the world. This amongst Costa Rica’s rapid shift to renewable energy sources makes Costa Rica one of the most environmentally friendly places of the world.

Several of Costa Rica’s travel providers have been recognised worldwide for their commitment to the planet-positive tourism. Ecotourism helped Costa Rica preserve natural areas throughout the country and thanks to its links to conservation and ecological volunteering it led to many initiatives. Costa Rican national parks expanded rapidly with their areas covering 21% of the total territory. Ecotourism encourages individual conservation efforts made by each visitor. Ecotourism has become a key to Costa Rica’s economic development with international tourism receipts having grown from $117 million in 1984 to $3408 million in 2018.

Image 08-09_ Photographs of ecotourist huts in Costa Rican forest promoting environmentally friendly travelling and being closer to nature. Ecotourist huts are usually run on renewable energy to make them carbon neutral.
Conclusion_ Costa Rica provides a great example how a country can bring back its natural resources and make the economy grow at the same time. Through using more environmentally conscient resolutions, it is
possible to regrow large areas of a rainforest, maximise the use of clean energy and increase the country’s GDP through eco-friendly tourism. This model could be viably transferred to Borneo which equals Costa Rica in its biodiversity and potential for the use of renewable resources. Ecotourism and volunteering programmes could allow to bring back Borneo’s forests and allow its endangered species to grow their numbers. This project aims to find a solution that would help faciliate that process in Indonesian province of Borneo, Kalimantan.

TWISTED PELLUCIDITY
The Tropical Climate is controlled mostly in regard to the position of the Inter Tropical Convergent Zone which is an area of low pressure marking the point of trade wind convergence. Both of those roles are critical for atmospheric circulation and affect the formation of the Hadley Cell.
However always near the equator, the location of the ITCZ varies throughout the year as much as 40° to 45° of latitude north or south of the equator depending on the pattern of land and ocean. It relates to the altitude of the sun marking the point of its highest position in the sky. In tropical latitudes ITCZ is responsible for the migration of low pressure and therefore the shifts in seasonal tropical rains.

Tropical Climates characterise themselves with having 2 seasons: wet and dry. When the air rises above the ITCZ creating a low pressure zone, high humidity and rainfall occur. Further north and south of this zone the air begins to get warmer holding as much water vapour as cold air. Relative humidity falls and moisture gets locked in the warm air. As a result the atmospheric conditions are hot, dry, calm and clear skies with high pressure - Tropical Anticyclones. As the ITCZ migrates north and south, the warm dry highs move with it.

Tropical Climate Key Information
01. Tropical Rainforest Climate
02. Tropical Monsoon Climate
03. Tropical Savannah Climate
Tropical Rainforest Climate is found within 10° to 15° latitude of the equator in the areas dominated by the Inter Tropical Convergence Zone. - with an exception of Santos area in Brazil which is located outside the tropics yet still has this type of climate. With at least 60mm of rainfall each month, it is typically hot and wet without any distinct dry season. The change in temperature between night and day can be larger than the average amplitude throughout the whole year.
Tropical Monsoon Climate is the intermediate climate between wet Tropical Rainforest and dry Tropical Savannah. It has more than 100mm of average monthly precipitation however throughout its driest season this average is smaller than 60mm. Its driest month occurs usually at or soon after the winter solstice for that side of equator. The major contributing factors to this climate is its relationship to the monsoon circulation - seasonal change in wind direction resulting from the different heating of land and water.
Tropical Savannah Climate has a pronounced dry season with less than 100mm of average monthly precipitation and its driest month having less than 60mm of rainfall. The dry season in this climate can become severe with drought conditions occurring during this period. This climate often features large grasslands scattered with trees where grass is particularly tall and coarse. Most areas of this climate are found at the outer margins of the tropical zone.

04. Tropical Revolving Storms Tropical Revolving Storms form near the hot and humid season over warm tropical waters in relationship to the migrating ITCZ. The converging trade winds are central to the formation process as they affect the development of low pressure areas along the ITCZ which create strong divergence that starts the formation of a tropical depression. As the convergence gets stronger, the tropical depressions clustered around the low pressure areas become more organised and revolve around each other forming a tropical cyclone. The strengh of the cyclone is related to its position - those nearer the equator are weaker than those on each side of it.

Mangrove Forests are unique to coastal conditions, growing in saline soil and brackish water. They are a very dynamic and highly productive ecosystem filtering pollutants from the water, stabilising and improving the soil quality whilst protecting the shores from erosion. Thanks to their tough root system they slow the water flow and increase the deposition of sediment. Mangrove Forests create an important breading ground for many fish, prawns, crabs as well as other marine animals supporting a number of endangered species. Mangrove trees are also a valuable resource that when harvested sustainably can provide a number of uses.

Image 10_ Peat Swamp Forests are rain fed which means that rain and air are the only carriers of nutrients. The peat dome can contain 13 times its weight of water and large amounts of CO2 - up to 20 times more than nearby lowland forests.
Freshwater Swamp Forests are located just inland from the southwestern coast and are associated with inland lakes, low-lying river basins and coastal swamps. They exist where rivers meander through flat alluvial floodplains that usually follow the mangrove forest. They are either periodically or permanently flooded with mineral-rich freshwater, without any substantial amount of peat and of a high pH - usually above 6. This makes them particularly rich in species of both fauna and flora that inhabit it. Mature freshwater swamp forest has trees of approximately 35m high.
Peat Swamp Forests differ from Freshwater ones mostly by source of water - rain as opposite to riverine; and presence of deep peat. As peat swamps are not drained by flooding they are largely nutrient - defficient and highly acidic - with a pH usually less than 4. Even though they are not as biodiverse, they are known to provide habitat for many endangered species, play a vital role in lifes of indigenous people by providing food, water, fuel, timber sources and other as well as constitute a critical buffer against flooding. Those forests are most commonly converted into oil palm plantations.

PALM OIL is an edible vegetable oil native to Africa and brought to South-East Asia over 100 years ago as an ornamental tree crop. Currently Indonesia and Malaysia constitute over 85% of global supply of palm oil. Palm Oil is one of the major drivers for deforestation of some of most biodiverse forests in the world, destroying the habitat of many endangered species like orangutans, pygmy elephants or Sumatran rhinos. The conversion of carbon rich peat soils and the forest loss make a large contribution to climate change through enormous emissions of greenhouse gases. Palm Oil Plantations are also known for their exploitation of workers and regular child labour. The Roundtable of Sustainable Palm Oil [RSPO], formed in 2004, is one of the organisations formed due to raising concerns about the impact of palm oil industry on environment and society.

Palm Oil is a very efficient crop producing more oil per hectare than any other one. It currently supplies 35% of the world’s vegetable oil need on only 10% of the land. In order to get the same amount of oil from any other crop, you would need between 4 to 10 times more land which would only move the deforestation and habitat loss problems to different parts of the world rather than getting rid of it. It is also a source of income and occupation for a number of people in those areas of the world, making up the GDP of emerging economies. Palm Oil plantations currently cover 27 million hectares of the Earth’s surface - an area the size of New
Zealand.

Palm Oil Production Process
01. Germinating of the seeds preparing them for planting.
04. The seedling is moved to the palm grove when its 16-18 months old.
02. Young seedling stays in the container for 4-5 months producing a new leaf every month.
03. When seedlings are ready they are moved to the nursery where they stay for 1 year.
05. For several months oil palm produces only male flowers and then only female flowers. Afterwards the fertilized female flowers turn into a cluster of fruit.
06. A cluster of fruit is harvested when the fruits turn red and when 5 to 6 fruits drop to the ground.
Indonesia has 3rd largest Tropical Forest yet it ranks 2nd in the world for tropical
deforestation
498 000 Ha/year 07. The clusters can be cut with different tools such as chisel, machete or long- armed sickle depending on the age of the oil palm.
08. There are 2 commonly used methods of extracting oil - dry with mechanical press and wet using water to leach out the oil.
09. At the end the oil is clarified to separate it from any impurities and stored usually at 50°C.
Almost
90% of palm oil plantation in Kalimantan came on the expense of forest cover.

Oil Palm Tree: Key Facts Kingdom: Plantae Family: Arecaceae Species: Elaeis guineensis Other names: Elaeis dybowskii, Elaeis macrophylla, Elaeis madagascariensis, Elaeis melanococca, Elaeis nigrescens, Elaeis virescens, Palma oleosa
Trunk (70%) Inflorescence (1%) Cabbage (2%) Spears (2%) Rachis/Frond (20%)
Description: Oil Palms are single-stemmed trees which grow up to 18m tall. A young oil palm produces approximately 30 leaves a year whilst a mature example bears only about 20. The pinnate leaves reach 3 - 5m in length. The flowers of the oil palm grow in dense clusters with small individual flowers, each made of 3 sepals and 3 petals. The palm fruit matures in 5 - 6 months from polination.
Leaves (5%)

Oil Palm demands a rather low nutrient uptake in its first year but increases steeply during the years 1 - 3 when harvesting begins. Earlier fertilisation of soil alongside better can result in a significant increase of the yields in 3 - 6 years since planting. Elaeis Guineensis originated in Guinea (Africa) and was first introduced in Indonesia on Java by the Dutch in 1848 and to Malaysia in 1910. First Malaysian plantations were operated by British plantation owners and listed in London until as recently as 1960s and 1970s. Federal Land Development Authority (FELDA) is the biggest oil palm planter in the world with plantation area covering approximately 900 000 hectares in both Malaysia and Indonesia. Its success led to establishment of other development schemes which help support small-farmer oil palm cultivations.

The Native Inhabitants of Bornean Indonesia. The native people of Borneo come together under the name DAYAK. This term describes approximately 200 riverine and hill-dwelling tribes each with their own customs, laws, language and territory. Even today most Dayaks still follow their folk ancient animistic religion however many have also turned to major religions such as Christianity or Islam. The Dayak languages are classified as part of Austronesian languages.
MURUT PEOPLE
In the past the Dayaks have been feared for their elaborate headhunting traditions using human sacrifice to pay for fortune and luck with their crops and cultural events. In order to establish peace with the Dutch colonisers the Dayaks have agreed to end their headhunting procedures in 1874 however in certain tribes they have resurfaced in the 1960s and are still practiced today. Murut people inhabit the northern-most hill areas of Borneo and comprise of 29 subethnic groups. They once suplied the military for the Sultans of Brunei.
Traditionally Dayaks mostly occupy themselves with agriculture based on Integrated Indigenous Farming System. Each tribe specified in farming on either hill or flat land and the agricultural terrain was distributed in that way. For economic reasons, the Dayak collect jungle produce however recent market has turned them mostly into planting crops such as cocoa, rubber and palm oil. The main dependance of Dayaks on agriculture has made them dependant on many palm oil plantations whilst their land has been taken under customary claims by Indonesia, threatening the political landscape in many parts of Bornean Indonesia. Those not involved in palm oil cultivation, seek employment in the trade of palm oil.

Alternative Oil Crop - soyabean
Nutrients and fertilisers are distributed through a set of growth platforms within farming areas.
Water is distributed through a centrally located tube providing water for farms and the household.
Water is regularly sprayed on the plants through a series of sprinklers in farming areas according to their appropriate needs. Orangutan Food: Fruit Berries Shrubs i.e. blackcurrant Nutrients are pumped through a centrally located nutrient shoot extracting necessary minerals from the ground and mixing it with naturally sourced fertiliser.

Sustainable grazing field surrounding the tower provides food for the family and fertiliser - manure - for the farm.
Collected water is pumped to provide necessary utilities within the household. Remaining rainwater is taken into the ground providing necessary moisture and partly diverted to sustainable grazing farms next to the tower providing necessary irrigation.

Design Development
Initial Concept: Vertical Farming Towers
The initial concept of the project included Vertical Farming Towers based on a tower that I completed as a Final Model for Brief 01. Through scaling of the tower, it could be divided into sections: open farming layers made from the modules allowing large amounts of sun and water into the structure and straight woven sections in between - more shaded and protected from the tropical downpours. This division would allow for growth of different types of plants: soyabean crop in the module part and small fruit in the shaded part. This correlates with the demands for sunshine and water of each of those plants as well as a potential area to grow those on. Soyabean has been chosen as a replacement for palm for oil production of the community. The initial proposal included solid floor plates separating each of the sections and a thicker secondary structure behind for further support. Central circulation core housed ladders and staircases to allow movement in between the floors. The bottom section of the tower, which was thought as a living area for the farmers family has been protected with 2 additional layers of weaving, providing shade, privacy and waterproofing. Since the scheme is located on Borneo, in a tropical rainforest, it was crucial to raise the towers off the ground to prevent flooding. This has been done by a woven screen floor to which the towers tapered to.
Agata Korzeniewska
TWISTED PELLUCIDITY
This was a very early scheme which certainly did not seem like an overall good solution that made the most of the compression strength of the twisted module. The towers were significantly too large to be easily constructed by a person therefore it lost the handcrafted quality of the original systam. Simple scaling of the tower from Brief 01 compromised the innovative structural qualities of the module and required additional secondary structure which made this concept not as exciting or innovative. Therefore I have decided to try to look at this conceptual idea again at a different scale, trying to make the most of the discovered structural strength of the modules and maintaining its handcrafted, human scale.

Design Development
Using the system at a human scale. Square set made of 4 columns and tensioned roof.
Following the large, scaled up tower, I amended the design to reflect the human, handcrafted scale of the system. Using columns at diameters I have tested whilst making physical model for Brief 01 I created a set of columns that could be laid out on almost any - regular or irregular - geometric shape. The columns can be connected with plywood strips which stay in tension induced by the bend-active forces working on the plywood when bending it and fixing at both ends. This results in a complex, woven structure that gives rigidity to the entire 4-column design set, keeping the columns in place. Through the arches created by bending of the strips, a canopy unravels providing continuously woven and structurally stable shelter.

Design Development
Hexagonal Tower made of woven columns with a tensioned roof and floor plates supported of the columns.
The shelter created through connecting the columns with bent and interwoven plywood strips can be developed on a variety of shapes. Since an original palm oil plantation grid is based on hexagonal shapes, it seemed only natural to use a hexagon as a geometry base for the plan of this design. The woven canopy, however rigid enough to support itself and withstand environmental loads, is not capable of holding live loads of humans walking on it. Therefore to create a tower I have designed a double layered weaving system where part of it tapers to create the shelter and another set continues straight up which allows for the attachment of solid floorplates. This design option has been used for my Applied Technical Studies submission. Unfortunately, solid floorplates seem rather alien to the delicate woven system. More could also be done regarding the columns which could eventually become inhabitable. Following this design I have moved onto less solid floorplate system made out of nets hung inside the fattened columns which is described in detail later on in this portfolio.

Physical Model testing the possibilities for tensioned woven roof.
This physical model was made to test the hypothesis of connecting the columns via woven, bent plywood strips to create a coherent enclosure. The bend-active forces and tension put on stretching the strips between the columns made this a very successful test model showing the viability of this proposal. It opens many possibilities to connect as many columns as desired, giving them additional strength and keeping them in place.

The geometry of the module naturally lends itself to housing plants to allow vertical farming. In order to understand how would such system work and how many plants could it hold I have tested a few options of the pockets. Even though the woven one seemed rather coherent with the other parts of the system, it proved to be inefficient in terms of number of connections, space created and amount of time needed to make it. I then made the pockets out of jute textile which I have sewn to the module using thick jute thread. This option is 100% natural and provides an optimal amount of space for a plant whilst having sufficient porosity for watering the plant.

Vertical Farming Tower: Privacy Pods.
Each pod is covered with jute textile roof separating it from the level above.
The pods to double structure. allows for plants.
provide privacy thanks layering of the column The gap in between natural watering of the
Jute nets are used to construct comfortable, lightweight and sustainable living/resting areas.
Vegetables for the users are grown in the external pod layer, located in the jute pockets created in the twisted modules.
Woven internal core filters light through allowing for movement in between the spaces and shading to create comfortable sleeping areas.

Final Design Proposal
Vertical Farming Tower: Net staircase in central column.
Jute is grown in the module pockets around the central column providing the fibre for nets throughout the community.
The nets are connected through a tensioning tube that keeps the structure together. It is prefabricated on the ground and then attached throughout the column to form a spiral staircase.

Final Design Proposal Community Washroom
Each shower room is covered with jute textile individual roof protecting it from excessive rainfall.
Central Column houses 2 sets of modules which host jute plants needed for their fibre.
Central Core is used to transfer rainwater to a rainwater collection tank.
Open interior of the column allows for the flow of rainwater, watering the plants and collecting the remaining amount in a rainwater collection tank.
The modules surrounding shower rooms house jute plants watered using rainfall and moisture from showering. The sink is made out of woven support and bent plywood surface. Dense and thick jute textile is used as partitions to separate individual sections.
Sink support is woven in the same way as the closed part of the system, tapering to allow a smooth connection to the net floor.
Rainwater is collected in a rainwater collection tank and used as a sustainable water source.

Final Design Proposal
Hanging Jute Net Bridges
Tensioned woven wooden strips are used to connect neighbouring towers providing a seamless canopy and support needed to hang the net bridge. This is using the same bent-active force of plywood and the curvature resulting from connecting two woven column tops as tested using physical model for the main roof canopy.
Jute Net hung of the woven canopy.
Thick Jute Rope is used to hang the bridge of the woven roof.
