Combining the advantages of the first and second prototype, S House 3 realizes higher durability, flexibility and easier construction, while maintaining the affordability and lightweight of the series. The main structure is made of lightweight steel as in “S House 1”. Slender steel lattice walls secure a supporting rigidity of whole frames, so that the number of beams is minimized, reducing steel quantity greatly compared to previous prototypes, the weight of whole structure is only 1,200kg.
Like our second prototype, the basic strategy of construction is a combination of modular structural components and DIY finishes. Galvanized steel frame and precast concrete foundation guarantee predetermined stability and accuracy. The lightweight structure allows smaller foundation and transportability by small boats, since waterways are still the dominant transportation in certain areas in Vietnam. Light frames with simple bolted connection also encourage dwellers and neighbors to participate in construction. It takes only half a day to assemble the whole structure with six people.
