During the middle of the 20th century in major French cities, the typology of office buildings evolved dramatically. This tertiary architecture is characteristic of the economic boom following the Second World War.

The International Agency for Research on Cancer (CIRC) tower is part of this architectural movement and is a building representative of its time. Built in 1972, it is one of the first high-rise towers in Lyon. The project was developed by two architects from Lyon, Pierre Bourdeix and Paul Guillot, whose works have left an impression within the city of Lyon. It is a landmark construction that demonstrates its ability to fit into the international architectural style and to establish its position in world construction techniques. The creation of the IARC is also an important step in the history of medical research, particularly for the commitment of Member States in the fight against cancer. It is the first tower in Lyon with a lightweight prefabricated façade. The IARC tower is easily identifiable as the only high point in the district; it rises like a beacon visible from several vantage points within the city.

The world cancer research organisation will leave the 8th arrondissement to join the Biodistrict district in Gerland in the 7th arrondissement in 2023, freeing the site of its occupants, which is an opportunity to give the building a new lease of life, to accommodate new uses that are appropriate for this site. Bidding teams are invited to find a new purpose for the site and propose an iconic project for the low-carbon and resilient city that we aspire for Lyon and for the world.

Expected Land Use
In order to give a new start to this entire site and because of its strategic position at the heart of three major urban centres, the City wishes to see ambitious and innovative reconversion projects emerge. See the Site Requirements for more information.

Type of Property transfer intended
The mode of transfer of real estate property rights is not defined. The lease, emphyteutic form or assignment are both possible. The goal is to run an operation with a single lessee who is responsible for a worldwide project.

Virtual site visit
Due to security measures related to the CIRC activities, it is currently impossible to visit the site, but visits will be organised during the second phase of the competition. In the meantime, potential candidates can visit the site virtually following the link below.

Plot Area: The city's land base covers 8,723 m2 in the 8th arrondissement, in a mixed urban planning zone (the PLUH's URm1 zone).

Site Ownership:
 The City of Lyon is the owner of the premises, with complete ownership contingent on the completion of the site's terms of release, including the payment of an exit indemnity to the occupant. The site is now inhabited by the IARC; but, due to a move of this institution, it will be free of any occupation and function by the beginning of 2023.

Deadline for the submission of the Expression of Interest:
 September 20, 2022 5:00 p.m. (local time - GMT+1).
