Fundamentally it was a question of re-conceiving the two architectural languages represented in the building. The core of the building originates from 1912 - 1916 and it was extended - and spoiled - in the 60s.

The refurbishment is a classic example of how to treat a national monument. Openness, light and clear structures are now once again the dominant features of the ETH building. This is exemplified by the atrium hall: with its three floors, it has regained its impressive height. New staircases in a voluminous space connect the hall with the entrance level. The elegant exhibition structure represents an additional, new feature.

The cost-effectiveness of the building has also been raised by optimising the laboratories and combining the institutes as well as through structural renovations and technical improvements.

Interior Design

The three-story atrium opens up unobstructed to its fullest effect, giving free reign to the interplay of matte and gloss.
