• The Bergeron block, which is being completely rebuilt, is the last stage of the “creation district”, to the west of the island of Nantes.

  • The operation brings together housing, offices, as well as a few workshops and shops.

  • The Doctolib group will set up its regional headquarters there (750 employees).

It's hard to miss when you visit the Machines de l'île.

To the west of the island of Nantes, between boulevard Léon-Bureau and rue Arthur-III, a spectacular construction site has been revealed for several weeks to the sight of many passers-by.

The last Alstom halls (known as Bergeron), which previously occupied the site, were demolished this autumn.

They freed up a large plot of around 6,000 m2, “the last block to be built in the creative district”, indicates the development company for the island of Nantes.

What to do instead?

The operation, led by the promoter Quartus, aims to build a total of five buildings culminating at 8 floors.

Two buildings linked by a walkway will accommodate 39 apartments (T2, T3, T4 and T5), including 14 social housing.

Eighteen are still available for sale.

Two other buildings, also connected by a footbridge, will be dedicated to the regional headquarters of Doctolib.

The famous platform for making medical appointments intends to set up a 7,800 m2 “campus” there, comprising offices but also two multipurpose rooms, a company restaurant and a gym.

Nearly 800 employees will work there.


A well-known architect on the island

A fifth building will be assigned to “creative and cultural industries”, of the craft type.

There are also three shops on the ground floor.

The entire project will be distinguished by its numerous balconies, terraces, shared gardens and wooden cladding.

“It's a noble material, a favored solution for achieving low-carbon performance,” explains Benoît Guillet, program director at Quartus.

Another originality: rainwater will be recovered and reused for the sanitary distribution of office buildings.



The site is currently at the “deep foundation” stage.

The structural work, marked by the appearance of cranes, will begin in mid-February.

As for delivery, it is scheduled for "early 2025".

“The Bergeron block is a major project for Quartus, very qualitative, on an exceptional site, close to the Loire, the future CHU and the future tramway”, concludes Benoît Guillet.

The architect of this operation is none other than Alexandre Chemetoff, the French urban planner who authored the first guide plan for the transformation of the island of Nantes in 2000.
