S House 3 is a 31.6 m² house that can be assembled in one day and it was designed to be transported by small boats to all Vietnam regions. Although the original project had only a single room, it was designed considering the possibility of dividing in multiple rooms according to the needs of the residents. The main structure is made from lightweight steel (1200 kg) and the walls are made of Slender steel lattice that support and rigidify the frames. The pedestal is incorporated with a concrete foundation. All components were designed to be lighter than 60 kg to facilitate transportation and construction. Different materials can be used for cladding and can be replaced by dwellers.
There is no technical support provided and users are expected to maintain the product on their own.
