Topic 4: Projects for future of housing

Serendix has completed japan’s first 3D-printed house is just 23 hours and 12 minutes. serendix is the first housing manufacturer in japan to realize a 3D-printed house. dubbed sphere, it features a 20-metric-ton reinforced concrete frame, and less than 10 m2, making it except from japan’s building regulations. the rib-reinforced double structure clears the heat insulation performance of european standards, and engineers have made sure it also satisfies the high seismic performance of japanese standards.

The first phase of the 3D printing construction technology,  “Wolf Ranch” project, consisting of 100 houses, is nearing completion in the state of Texas, USA. These detached homes, which are being constructed using 3D printers, will be the largest residential area produced in this manner. They range in size from 140 to 195 square meters, featuring 3 or 4 bedrooms, 2 bathrooms, and smart home technologies supported by solar energy. The prices for these homes vary between $476,000 and $560,000.

Japan’s Kitakyushu University has taken an unusual approach to low-cost and sustainable housing construction by focusing on an unconventional raw material: baby diapers. In the developed model, used baby diapers are washed, dried, and then blended with water, sand, and gravel for 28 days. This process enhances their interaction with cement. As a result, using this alloy in construction materials like concrete and bricks can lead to savings of up to 40 percent.
