The Felsenhaus is a unique private residence embedded directly into a natural rock formation. The architectural concept is based on the archaic idea of living within a cave, translated into a contemporary living environment that merges nature, structure, and precision engineering.

The project is defined by the direct integration of construction elements into irregular rock surfaces. Rather than imposing a traditional building form, the architecture follows the natural contours of the stone, creating a seamless transition between built space and landscape.

Metall Ritten was responsible for the execution of glass façades, steel structures, and custom metal elements. The installation work required exceptional precision due to the highly irregular geometry of the rock walls and the limited tolerance for measurement deviations. Filigree materials such as structural glass were carefully integrated into the rough natural substrate, ensuring both technical performance and visual lightness.

The result is a highly atmospheric living space that combines raw natural conditions with refined architectural craftsmanship, balancing protection, transparency, and material contrast.
