To build simply – is that even possible? Can building be an easy task today, given a building culture shaped by standards, an oversupply of construction materials, and industrial production methods? Construction and building services engineering are becoming increasingly complicated. Nevertheless, the Technical University of Munich (TUM) has established a research group dedicated to “Simple Building”. But the question they’re investigating is how the principles of simple construction can be applied without restricting users’ comfort and behaviour. The memorial in Gardelegen by BHBVT, with its 72 cm thick walls made of lightweight concrete, won us over with its simple details. The monolithic structure, however, required a lot of building material. The temporary homes in Barcelona have a smaller ecological footprint. They consist of reused shipping containers.
