This magnificent building in the heart of Lausanne's commercial centre was built in 1912 and has been listed as a note 2 on the inventory of historical monuments since 1975. It is twinned at the opposite corner of the street creating an iconic ensemble on Rue de Bourg.

Our intervention is focused on the entrance to Rue Lion d'Or 1 and the three upper levels of the building, which were formerly used for logistics and for the operation of the commercial surface of the emblematic Lausanne brand Annabelle. These were transformed to accommodate quality administrative spaces by strategically incorporating modern facilities while respecting the character of the building as much as possible.

The greatest challenge of the project was to manage the renovation and upgrading processes and the progress of the work in an occupied site. The original building elements are maintained, renovated or restored wherever possible.

This project requires the mastery of all the skills involved in the field of renovation, conversion and restoration.
