Context of the project

L’Office des Habitations à Bon Marché (HBM) (ou : Inexpensive Agency of Housings) from the Seine, leaded by Henri Sellier, had launched between 1921 and 1939, a program of 15 garden cities inspired from the Howard Ebenezer English author’s theories. Henri Sellier has the will to create “a group of cleaned housings to guarantee the decongestion of Paris and its suburb”, and “show that we can ensure to the labor class an housing with the maximum level of material comfort and hygiene conditions”.

Or nowadays, the HBM Bolivar-Chaufourniers-Moreau property group, built between 1924 and 1930 by the architect Charles Heubès in the 19th district of Paris, doesn’t belong anymore of the 15 garden cities program, because it doesn’t present an optimal quality of life for the tenants.

Consequently Paris Habitat wants to carry out a big operation to back up the feature of the housings, improve their technical state, and create a good quality of life for the tenants. Therefore Paris Habitat has chosen the De Jean-Marin’s architect office (mandatory) and ALTEREA to renovate this property complex.

Objectives of the project

  • Bring again to the group an urban consistency to solve insecurity problems
  • Think over the outdoor layouts defining the new public spaces / residential housings / private works

  • Organize a group of construction works respecting the Clean Construction Site Charter (Charte Chantier Propre) and the operation’s rules about the historic estate
