Before the renovation, this loft-like building was the ruin of a locksmith’s shop from 1904 in Stuttgart’s Lehen district. As the workshop building was in a very poor condition to begin with, the renovation was extremely risky with no guarantee of success. The aim was to restore the historic structure while creating a modern living space using only natural and regional materials. Particular emphasis was placed on materials and products that combine aspects of environment-friendliness, solidity and durability. That’s why our switch systems and ceramic lights were chosen for the old locksmith’s shop.
