Dufourstrasse 49, Zürich
The street-facing part of the property at Dufourstrasse 49 is protected as a historic monument. The part facing the courtyard is a new build. The property was completely renovated in 2017, and the listed historic building together with the new building provide an interesting contrast. The office space was fitted with a hygiene ventilation system and hybrid cooling ceilings. Lake water is used for heating and cooling.
