Casa Rotonda... une villa rotunda ? L'évocation est cynique. Il s'agit en fait pour Rodrigo Garcia Gonzales & Jaime Fernandez Calvache de l'ETSA Universidad Politécnica de Madrid avec Ignacio Borrego, professeur, d'investir les ronds points de la ville, espaces inusités. Pour ce faire, des structures amovibles, mobiles et modulaires ont été imaginées. Un parti dézipable.
Le texte de Rodrigo Garcia Gonzales & Jaime Fernandez Calvache
The zipizip is a new concept of housing mobility. The main aim is to compress to the maximum all the elements of the house in order to transport them easily.
The zipizip is located in the roundabouts. Infrastructures that are growing in number all over Europe. The roundabouts are always in the middle of everything and have a fantastic connection, but is impossible for the people to use them. These spaces have water, electricity and regularly have some grass.
The house plan is hexagonal, the perfect shape to be linked horizontally with any other units as a honeycomb, where there are infinite different combinations. Also the structure of the casa rotonda is thought to grow vertically, so it can have more than two floors. The special thing about the zipizip system is that all the structure is deployable at one time.
The lightweight structure is made of aluminum, the junctions are made by inox steel. The floor can be done in different materials as wood, metal or plastic. There is one floor module that is 'perched' and screwed in the structure. This module is supposed to include the electrical net and the lightning system. The interior skins are made of paper or fabric and the ventilation skin is made of recycled polietireno. The furniture is made of cardboard and paper, because is easy to assemble, cheap and light.
All the structure of the zipizip is made in a singular way so it can be carried in one regular van, and to be set it up with only two people and in a short period of time. It is easy to assemble and also easy to disassemble.
The structure of the zipizip is a new system of deployable structure. This structure deploys in the three dimensions and it is made with the scissors system in such a way that the movement of opening and closing of one of them makes the entire structure to move. The mechanism becomes rigid when the structure is fully developed.
The structure will be placed on the top of the van, connected with the first floor. The own weight of the structure helps it to deploy, equilibrating the first and the top floor. The structure will go up and down with no need of any extra element to deploy it as hydraulic pistons or so. The structure of a single unit reduces his volume in a 97,6% when it is packed. The structure will be fixed in the floor with removable elements or it can be ballasting with water tanks or with your car. We have prototyped this structure and we can see how the deployment works. We have even made a prototype of 6 floors. This high structure will be suitable for those places where there is a high population density.
Bio climatic strategies
There are three different skins, all of them can be folded. The first one is a honeycomb shadow skin. This last layer adapts each facade to the solar requirements, according to the orientation and with the help of the different bioclimatic diagrams. The hexagons of this facade could be more or less close to provide more or less direct light.
The next skin is a transparent plastic layer that regulates the ventilation. It could be adapted so that the air that is inside moves: int-ext , ext-ext or int-int. The last skin that is inside the house is made of fabric and paper and with this one we can regulate how much luminosity and privacy we want in the different rooms.
All the roundabouts are connected to the electrical net, so it will be easy to plug in our house. Also the zipizip provides some energy with three wind helixes located on the roof that convert wind power to electricity independently of the direction of the wind.
