Designed by German architect Matthias Bauer, principal of MBA/S , Villa H36 at Stuttgart, Germany is shaped entirely of insulating concrete. Conceptually, the roof and walls are malleable like clay and cast from the same concrete material offering innovative seamless construction to eliminate additive thermal barriers. Also, the material qualities of insulating concrete avoids typical environmental and building physics issues. The rough-sawn formwork provides a rich surface similar to a natural stonewall balanced with large openings bringing sensational light and dimension. All surfaces are haptic and warm without hollow sounds.
The natural, composite material achieves its outstanding thermal insulation by replacing the stone aggregate with foam-glass, and adding 25% air to the cement mixture. This permeability allows for ideal temperatures and moisture balance. H36 remains warm in winter and cool in summer for longer period. Structurally the house is a monolith with a folded shell bearing on two walls. The concrete was researched and tested locally by MBA/S and a team of experts.
