PROJECT DESCRIPTION

Nowadays, most of the construction of curved surfaces in architecture requires molds, such as CNC. However, these methods are time-consuming, material waste and labor waste. Shell project investigates the involvement among virtual reality technology, human body and computer to achieve the goal of fast and precise assembly for curved surfaces without any molds. Compared to other curved surface building technologies, the use of augmentation can not only save time, material and labor, but also boost the construction process. In material, we combine “WBA” sheet and EVA foam to make every pattern of the model. Both of them are stretchable when heated and hard when cooled. In addition to that, “WBA” will be sticky after heating. This property can be used in connecting two different “WBA” together without wasting other materials to glue them. Besides, we use the heat gun to control material deformation by temperature, heating time and heating angle to achieve the target surface. In modeling process, with the help of virtual reality equipment, like HoloLens, we establish a real-time feedback system to achieve better interaction between human and machine. With HoloLens, designers can see the target surface in reality and control the heating degree of “WBA” and acrylic sticks precisely. And then we can complete the whole construction process step by step. In this case, the construction of curved surface no longer requires a mold and improves accuracy. What’s more, based on the real time feedback system, designers and builders can make changes and do some updates at any time during construction process, which will make the curved surface construction more efficient and effective.

project by Eva Hild Ceramic Sculptures These hand-built sculptures, express delicate continuously flowing entities in thinbuilt clay. They reflect varying degrees of external and internal pressures, and how, as a consequence, perception of inner and outer space is changed or challenged.

project by Philippe Block Thin Double-Curved Concrete Roof In this project, fabric played a significant role of shaping curved surfaces. Consequently, We decided utilized fabric which is with a high degree of elasticity and be easily stretched to shape the flowing entities. And then, casting methods would be applied to convert the soft surface to the firm shell. 5

project by The Verymany, RESIDENTIAL SCREEN Ten years ago, MARC FORNES / THEVERYMANY invented a unique approach to describing and building a form: 'Structural Stripes.' In this "topological-walking stripe-based material system," thousands of parts, each unique, describe a form; the parts are digitally cut from a flat pieces of aluminum and fastened to neighbors -- achieving curvature and constructing the form in physical reality.

The metal bearing elements and a delicate space-enclosing skin consisting of an 0,7-mm membrane of elastic polyester fabric.

project by Roland Snooks The composite fibre installation compresses surface, structure and ornament into one intricate and irreducible assemblage. The Composite Swarm installation is an architectural prototype exploring the relationship of robotic fabrication, composite materials and algorithmic design. The complexity of the form and the excess of ornament make the prototype structurally efficient and minimize the amount of material used. 7

project by Tom Wiscombe

SEMI-RIGID CAR

This project is an investigation into the aesthetic and performative potentials of composite materials. Composites are more than a class of materials; they imply a paradigm shift in architecture, allowing real progress on the contemporary desire to allow formal, structural, and ornamental systems to interoperate. And structure is embedded into architectural surfaces rather than separated into vector frames.

project by Yusuke Obuchi Studio SYNERGIC A combination of latex, sticks and the principles of tension and compression govern our process and led us to design a hybrid structural system and generative geometry which explores aesthetic values and spatial boundaries. The hybrid system blends the discrete domains of structure and infill while the generative geometry has been developed due to the diffrerentiated patterns embedded in the latex material. BLOOMSHELL

According to the initial test results, we decided to use the elastic lycra as the model skin, the large elastic glass fiber stick as the model skeleton, and also used the plastic tube as the connecting material, the plastic tube wrapped outside can also reduce the probability of the glass fiber tube breakage. it is evident that due to flexibility, elastic materials are ideally adapted to different geometries of shells and are able to transform as well with diverse external actions.Whatâ&#x20AC;&#x2122;s more, applying elastic materials in surface could form form-active and lightweight shells in tension, which are among the most efficient loadbearing systems.

Understanding the material behavior is a must to proceed with the project. `To Do this firstly we need to understand the essential tools needed for our fabrication process. Taking the most easily available everyday tools experiments were conducted to understand the material behavior changes in the fabric after the stitching. different experiments were done with different fabrics and textures to see the changes in the form after the stitching patterns. Not only were there different fabrics experimented with, but also stitching pattern.

INITIAL PROPOSAL | CHAIR & PAVILION

As the first proposal,we think our project has a huge potential to be a pavilion as it could stand by itself steadly and posses a delicate inner space. After being casted, the surface would be solid and could be a shelter. "Bridges" between different surfaces could connect external environment and internal space of the pavilion, providing a comfortable space for wandering and staying.

PREVIOUS PROJECT | MATERIAL RESEARCH - SKIN STUDY Overall, based on the study of tensile curved surface and stripes-based shells, the efficient and quick way of fabrication curved surface is with free moulds and no temporary scaffolds. And in contrast to the top-down construction, bottom-up construction could meet more requirements for complexly curved surface fabrication. The Augmentation technology has great potential to be applied in architecture, allowing cooperative design, timely feedback and more precisely and effective construction. In this case, we look for the ways, to combine bottom-up construction with Augmented Reality technology together to achieve the open-ended design, 3D real-time interaction system, and growable construction. At the same time, we also wonder whether the system could improve accuracy and efficiency in complicated curved surface fabrication.

We plan to explore more possibilities of materials, and we found that EVA foam sheets may be a good choice for us.

In general, the control line of a minimal surface will determine the shape of the surface. We think all the shapes can be divided into different numbers and sizes of cubes. Therefore, in this logic system, we generate control lines for logical terms in different connection order of the cube vertices. The control of the surface edges by different vertex numbers will determine the difference of the surface form and complexity.

GYROID GENERATE LOGIC

The most obvious difference between the Gyroid system and the previous generation system is that it has stronger mathematical logic, so it will not generate completely random shape as before. And the problems of heavy andinefficient panelization in the previous physical model can be solved, because in gyroid system, each component is almost same, so we can make more complex forms if we get the division of one component .

This is because it is also a kiind of thermotic material which means could deform under a certain tempreature .And after some tests, we proved that this material can be bound with Worbla series material to be a more efficient synthetic surface system.

Ability of Keeping shape Stiffiness Smoothness Operation Covinence

Fologram is the most convient way to experience 3D content through hololens in mixed reality for now. It is used to collaborate with multiple devices to model in mixed reality, interact with holograms in real time as well. In the project, we combine the screen view with the actual mode through holographic in augmented reality space (NExT Lab.). At the beginning of the project, fologram software can also employ a device's sensor to identify the shape of every single panel then send data back to the computer. The computer then displays the details of each panel for the user , such as position, sort number, and so on. At the same time, fologram technology is used to add markup or change to 3D model in mixed reality space. When two devices run a fologram program at the same time, they can cooperate in real time to complete the modelling work. BLOOMSHELL

After finishing the physical components and design, builders can use augmentation to guide them to connect the components in an efficient order to achieve fast assembly. Firstly, by waring HoloLens, builders can use HoloLens scan the components to recognize the one, which should be placed in first order. Inside the view of HoloLens, people will see detailed information and the place of the component in the digital model will be highlighted. And then connect next one together. Thirdly, the second step will be repeated until finishing the fabrication. After that, when people finish the construction, if they want to continue, they will see the rest unbuilt digital parts, which is overlapped in their partly built physical model. And they can follow the connection order of components showed in the HoloLens to do the growable construction. BLOOMSHELL

As a result, integrating mixed reality in the bottom-up complex curved surface construction enables to eliminate errors as much as possible and allows designers to add new possibilities and do modification in time. In addition to that, with the enhancement of accuracy in construction, it can achieve the goal of avoiding unnecessary time and material waste, excessive labour input, as well as the increase in cost. On this preliminary research, we have observed that the application of mixed reality in the bottom-up complexly curved surface process can not only boost the fabrication of physical componentsâ&#x20AC;&#x2122; fabrication, but also help designers and clients to do an effective selection in various design results, change the style of components and generate creative outcome according to real-time feedback of partly built physical model.

ARCHITECTRUAL SCENARIO | SITE ANALYSIS The base is located in the Tiexi District of Shenyang City. It used to be a very splendid industrial area. Now there are many abandoned factories and abandoned industrial products. In our project, we use recycled materials and are also suitable for this site. Time has been accompanied by the historic landmarks of Tiexi Industry spanning a hundred years, the suffering of war plunder, the glory of the eldest son of the Republic, the trek of reform and transformation, together with the situation of the phoenix nirvana, even through the static picture, still far from listening The roar of the railway a hundred years ago. Less than half of the existing industrial plants are still in use, and even some of the industrial protection heritages are in a state of ruin, which is ruined and has potential safety hazards. The factory being used does not extend the original functions of the factory, but it has existed as a warehouse for logistics and storage. Prevailing Winds

ARCHITECTRUAL SCENARIO | RECYCLED ARCHITECTURAL MATERIAL In today’s world “going green” has become a top priority in our society, and sustainable buildings and design are at the forefront of this green revolution. While many designers are focusing on passive and active energy systems, the reuse of recycled materials is beginning to stand out as an innovative, highly effective, and artistic expression of sustainable design. Reusing materials from existing on site and nearby site elements such as trees, structures, and paving is becoming a trend in the built environment, however more unorthodox materials such as soda cans and tires are being discovered as recyclable building materials. Materials and projects featured after the break.Another popular trend regarding recycled building materials is the use of site provided materials. As environmental designers, we continually replace natural landscapes with our own built environment, and today our built environment is embellishing the natural environment in a responsible (while still aesthetic) manner.

Worbla’s Finest Art The original formula, Worbla’s Finest Art was the first of our products and is still a favorite. Incredibly easy to use with an activation temperature of 90 ° C, Worbla’s Finest Art becomes soft and pliable, allowing you to shape, form and mould the product by hand safely. The adhesive properties mean pieces can be joined without the need for glue, and scraps can be blended for zero waste. Non-Toxic and Skin-Safe, Worbla’s Finest Art can be used in classrooms, apartments, workshops and beyond without needing uncomfortable safety gear or complicated venting systems.

Recycling Process STEP 1 :

STEP 2 :

STEP 3 :

Take all those scrap pieces and put them together without any gaps.

put some wax paper both over and under the worbla and then heat them.

Iron it heavily, make sure to also turn it over so you iron on both sides.

STEP 4 :

STEP 5 :

STEP 6 :

Use rolling pin and start rolling.

let it cool down a bit, then remove the paper and get a kind of flat piece of worbla.

use the recycled material to make new components BLOOMSHELL

ARCHITECTRUAL SCENARIO | SITELOCATION

Bhuj Gujarat,India Bhuj is a city in the state of Gujarat, western India. Itâ&#x20AC;&#x2122;s known for its centuries-old buildings, many of which were damaged in a 2001 earthquake. Close to Harmirsar Lake, the 18th-century Aina Mahal palace is elaborately decorated with chandeliers, mirrors and semi-precious stones. Nearby, the Italian Gothicâ&#x20AC;&#x201C;style Prag Mahal palace has a bell tower that overlooks the city, and a courtyard containing a Hindu temple.

ARCHITECTRUAL SCENARIO | SITE ANALYSIS

Bhuj is a famous destination within India for observing the historic crafstmanship of the Kutch region. On the eastern side of the city is a hill known as Bhujia Hill, on which there is a Bhujia Fort, that separates Bhuj city and Madhapar town ( considered one of the richest villages in Asia ). It has two lakes namely Hamirsar and Deshadsar The climate in Bhuj is called a desert climate. During the year, there is virtually no rainfall.The average annual temperature in Bhuj is 26.3 ° C. The rainfall here averages 358 mm. Bhuj has a borderline hot desert climate just short of a hot semi-arid climate . Although annual rainfall “averages” around 330 millimetres or 13 inches the variability is among the highest in the world with coefficient of variation of around sixty percent– among the few comparably variable climates in the world being the Line Islands of Kiribati, the Pilbara coast of Western Australia, the sertão of Northeastern Brazil, and the Cape Verde islands.Apart from the cool mornings of the “winter” season from December to February, temperatures are very warm to sweltering throughout the year, which further reduces the effectiveness of the erratic monsoonal rainfall. During the “hot” season from mid-March to mid-June, temperatures of 40 ° C or 104 ° Fare frequent, whilst during the monsoon season they exceed 34 ° C or 93.2 ° F with high humidity except during rainy spells accompanied by cooler temperatures but oppressive humidity. 241

ARCHITECTRUAL SCENARIO | SITE ANALYSIS

In Bhuj many people worry about where and how they’ll get enough water. Without access to an improved water source, their days revolve around a walk for water: gathering enough to cook, clean, bathe — and of course, drink. There’s a larger, more productive waterhole 50 yards further on. There, women fill jerry cans, bathe their babies, wash clothes, and watch their cattle drink.The driest time of year is coming, bringing months when there is no rain. .As it gets drier, digging becomes serious business for adults. They’ll dig deep, some years going down 20 feet, hauling up filled jerry cans with a rope until the waterholes yield no water, only sand. The holes can cave in on people who are digging, and animals sometimes fall in and drown.
