Sustainable brutalist architecture hits new heights at this Stuttgart property, which has a monolithic, angular form. Local practice MBA/S Matthias Bauer Associates designed the hillside home in 2014 from insulating concrete, with no joints or added layers of insulation – the first of its kind in Germany. Its gabled, faceted form sits on a sloped site overlooking the German city, resembling a hewn rock. #design #inspiration #interiors #architecture
