The R4House prototype consists of two bioclimatic homes made from materials that close the loop. The energy consumption of both is zero due to its bioclimatic design, the solar panels and the geothermal energy source. The waste production during construction is also zero. Both homes are modular and built from six recycled shipping containers; low-cost and allowing flexibility. The 4 Rs stand for Reuse, Recover, Recycleand Reasoning with the latter being the most important says Garrido. “With the construction sector being very inert and sustainable architecture looking to establish itself, reasoning is required to redesign the construction process and lower its negative impact on the environment.” The construction materials as well as interior ones have been carefully chosen and are all recycled as well as recyclable.
The R4House is however not only ecological but also economical in terms of pricing. With the R4House, Garrido hopes to set an example for sustainable architecture in Spain and beyond.
