1. Bone-x Started as part of the 3rd year’s intensive, this project was then continued in pairs. (Binomial Katia Naouri). The objective here was to make a concrete shell as light as possible. The curves are optimized in order to match the efforts. The variable thickness of the shell distributes the material depending on effort constraints and lightening the structure.

The second constraint was to produce a mould that matched precisely the shape drawn with the parametric model (with Dassault System Digital Project).

2. Dymaxion Richard Buckminster Fuller’s Dymaxion house was the subject of a study during the fourth semester. This work was done in pairs (Binomial Fanny Roche). Issues of structure and inhabitancy were the center of the semester, and this house is especially interesting regarding this. The work followed three directions. The first involved the analysis of retrieved documents. The two other related construction of models, one showing the structure, but revisited in the form of a folding, the other showing the interior of the house. The difficulty was mainly to look for documents because there is little accurate plans and documentation on this house. 2.1 Pictures of the model 2.2 Structural caracteristics

3. Alter network Building units (working units in a broad sense) physically producing the city are knots around which built-up areas of living units are organized, by a technologically advanced selfconstruction process; then, once their productive task completed, they become public spaces of a particular character (no-work spaces) continuing this way to play a structuring role for the city. This is an almost symbolic proposition. Simulation allows to foreshadow the different topological possibilities of technical networks allowing the city to exist; mobility networks come after, optimizing travel distances. The FabLabs are gridshells whose form follows a parametric process according to their position therefore they are all different. The project does not take the “context� into account, that is to say the actual characteristics of the local territory, except to take advantage of some existing infrastructure. 3.1 Sketches of fablab’s interactions 3.2 Sequence of computational selforganisation testing 3.3 Three different organisations of the pattern 3.4 Detail : organisation around the fablab

This is a theoretical project for a sort of generic city: it could be placed anywhere, it does not follow a specific urban analysis. Its location close to HLM (low rent specific production method and construction technology), highlights the contrast between it and another construction technology (the proposed one), that is to say one other production of the built environment. The project highlights two things constantly overlooked in the actual architectural or urban projects, namely the technical infrastructure and the production method for built objects.

4. Intricate flow Very early, we defined ergonomics, ventilation, noise and sunlight performing requirements for our project. We started by designing and materialize compounds and welding, trying this way to anchor our project in an eco-conception. While working at the scale of components, we tried to make it intelligent and logic, we wanted the whole project to be intelligent and logic too. Therefore, the project is a permanent back and forth between large and small scales, between fiber, envelope and fonctions. The use of parametric and associative tools offers flexibility and high adaptability. Gradually, new concepts were added to the project, enriching it : - Creation of a structural system integrating logic flow management, temperature and light as much as possible. - Consideration of temporality with both permanent and ephemeral components. - In situ production of components for the structure and the envelope but also for daily life components. -Desire to abolish the logic of stages in favor of a system of interconnected “planes of existences”. These plans are offering the possibility to compartmentalize spaces efficiently as a “desk village”. 19

We looked for advanced technologies (electrical substrate, protocell) in order to combine them with more traditional systems (natural ventilation, comfort ventilation or humidity controlled ventilation, geothermal energy, principle of accumulation). In other words, we tried to build a reflexion about possible links between high-tech regenerative system and more traditional systems. These regenerative methods, both selective and conservative, are widely described in the book by R. Banham, “Architecture of the Well-Tempered Environment” (ed HYX, printed in 2001 A translation. Cazé), which was one of our basis for this project.

1. Who’s Next This project was realized through a partnership between ENSA Paris Malaquais and the ready-towear compagny Who’s Next First Class. We had 10,000£ to turn a 2,000 m² parking into a deck.We were a team of five second year students. The teacher Philippe Morel followed us. We assured the whole work, from design to construction, through costing and the details of execution. The assembly was particularly hard. We assembled more than 90 compounds each consisting of 12 cardboard discs. Metal angles specially designed for the occasion, building by rivets, kept the pieces of cardboard fixed together. More than 10,000 rivets were used, the building took five days.

2. EZCT : U-Cube system U-Cube system is an experimental device consisting of cubic hollowed Styrofoam. Cavities, responding to specific connectivity rules, in which a self-compacting concrete liquid Ductal ®is poured, forming a support structure with no outside contact. This lack of contact with holding polystyrene as formwork offers many advantages, including excellent thermal and acoustic insulation. Cavities, cut by a 6-axis ABB industrial robot, piloted by HAL ®, reproduce a three-dimensional mesh as continuous as possible (a surface as smooth and even possible), while the cubes obey to “digital geometry” rules (or “discrete geometry”). The project aims to integrate the architectural thinking of the possibilities and features of the computer as a “discrete state machine.”
Issues related to the project are fourfold. 1) Establishing a correspondence between the geometry of the construction and geometry present in a computer. 2) Anticipating the massive deployment of robotics (whose logic is discrete) not by adapting the robots to the models, but adapting upstream geometric models used by the architecture to robots. 3) Explore the potential of an economical use of the Ultra High Performance Fibre-Reinforced Concrete (UHPFRC). 4) Develop a different architectural notation, which would not be based anymore on plans or continuous dimensions (metric), but on a series of numbers describing the relative positions and directions of cubes in a discrete space (cubes are voxel-”volume elements “, by analogy with the pixels-” picture elements “).

3. Hyperbody This workshop took place in Rotterdam, in the premises of the TU Delft. It was a master class with Wes McGee and Dave Pigram. The purpose of the workshop was to create a concrete funicular structure, which mould was made of foam. The software Processing was first used to create a funicular system simulation and for the form finding. Once the form was found, the foam mould was cut with a robotic hot wire. To combine funicular structures with robotic hotwire cutting was the aim of this workshop. Separate blocks of the free-standing foam were cut, and then put together to form the mould. Unfortunately we did not have the time to pour the concrete inside. If we could have done it, we would have obtained a concrete framework.
