House at Regensburg

"Sustainability" becomes the catchword of responsible builders. The architectural profession for the first time started to think seriously about low-energy building after the oil crisis of the early 1970s. The result was a rash of experimental houses, lots of them were in rustic style to declare their "alternative", anti-industrial ideology.

The house at Regensburg is a logical design owing more to science than to sentiment. Its pure prism form and rational plan make it almost machine-like. The triangular shape is designed to collect solar energy which can be used to heat the house.
