Conceptual design for a house made of renewable materials and 3D printing.
Designcafe’s social activity” Designcafe’s vision of the SDGs” is a concept design that responds to the SDGs, an international framework with a target year of 2030, and to Society 5.0, a science and technology policy that is being promoted by the Japanese government as a key policy initiative for the entire industry. The concept house “CH-101” focuses on the sustainability and scalability of the building materials used in the construction of the house, as well as on the scalability and variability of the house to accommodate changes in the family structure. It is also the fate of housing to be able to expand and change in response to changes in family structure.
LIMEX, Japan’s first new renewable material, is a potential building material. LIMEX is an inorganic filler-dispersed composite material made from limestone and containing more than 50% calcium carbonate, which is attracting attention as an alternative to plastics and paper. If the material can be standardised, it will be possible to buy and sell the necessary parts on the aftermarket and recycle them without melting the material.
The design is based on a monocoque shell structure, which is strong and floats several metres above the ground to ensure resistance to water damage. As the cross-sectional shape is constant, it can be divided into parts in a “ring” and added to according to the volume of space required, making the volume of the space variable. For example, as the number of children increases, the volume of the space can be increased, and as the children become independent, the volume of the space can be reduced to make it more compact. The expandability of space can also contribute to reducing the wasteful consumption of energy, such as electricity and gas, which are essential for infrastructure. The idea is to reduce the number of construction workers by using 3D printers to produce parts. This could help to minimise the amount of construction work required.
Unfortunately, in 2021, most new homes are being built with non-native materials and new building materials, closing the door to sustainability. The future of housing needs to be sustainable and designed to cope with a declining population.
I visualize possibility of the 3 dimensional molding to have of the 3D printer with a polygon fixture.
As well as a mock-up, it produces it from a design and a design to a finished product throughout and can manufacture the 3D printer of these days. It is the example of the Dow Toray Corporation booth which exhibited for this exhibition that collected the state-of-the-art of the 3D printer in the cathedral. The theme of this display booth design is a polygon fixture. It linked the prescribed outline established by an exhibition in a polygon and I did it with sharp molding and suggested the possibility of the 3D printer.
