Barcelona-based architecture firm NOEM designed and built this prefabricated home for a couple in Castellón de la Plana, Spain. The whole building process was finished in just 10 weeks. It’s called The Smart Shelter and is intended as a place of leisure where the residents can enjoy the surrounding views.Transporting a house on one truck, assemble in a day and a half, and have her in a completely autonomous comfortable space. These were the three challenges of the project, and these have also been the great achievements of this prefab, modular, modern and ecological. Designed with the maximum use of space, allows a full kitchen, a dining room, a comfortable bathroom and a solution to sleep in less than 30m². The facilities allow the house to take advantage of solar energy to power their equipment in complete autonomy. The design and construction minimizes CO2 emissions.The project combines two prefabricated modules, an open space of 23m², and a compact core technology hub that concentrates all facilities 5,9m². The modules do not need heavy foundation, they can be assembled and disassembled, transported and reassembled in another location with the same or different configuration to meet the growing demand for versatility and mobility of housing.
