Ateliers 2/3/4/ Urbanism & Landscape is involved in various stages of urban projects: in pre-operational studies, urban project management, development of public spaces, drafting of urban planning documents.

The variety of assignments completed by 2/3/4/reflects its determination to find a synthesis among the various disciplines of urban planning, from domestic to territorial scales.

These various fields of intervention lead 2/3/4/into working with a number of collaborators: Landscape designers, geographers, transportation engineers, development economists, environmentalists . . .


Town planning

Reconciling the aspirations of residents to live in peaceful neighborhoods removed from the tumult of city centers without putting to waste new expanses of land, remains the challenge of the sustainable city.

In order to contain the urban sprawl caused by the impact of the automobile in suburban parisian towns like Argenteuil, Aubervilliers, Pierefitte, Saint-Ouen, etc., 2/3/4/faubourg endorses an approach that takes stock of each place’s capacity to handle intensification. 2/3/4/faubourg reexamines road and rail transport infrastructure, envisioning in which way an intersection can become a square, a road become a more accessible boulevard.


Water and light, prime materials of the green city, organized into layers, accompany the pathways that lead from public space to private space. Ateliers 2/3/4/’s research into unseen forms of density is an integral part of its proposals, a research continually perfected.


Urabanisme // Austerlitz

The Austerlitz train station neighborhood condenses onto its delimited urban block numerous highly relevant issues, including the city center’s expansion, the reclaiming and revival of the seine’s banks, construction height, the empty-density ratio, transport infrastructure, functional diversity, the reanimation of cultural patrimony, the appropriation of city land by the service sector, and the fundamental question of housing.

Thanks to the raising of the station hall’s roofing to 8.5 meters, the station and the avenue de France regain their sense. the link with the historic center established, the floors are connected.

The physical stature of the station’s hall restored, its silhouette stands out on the river.

The investment of industrial architecture here serves not only to enhance the workings of a large multifunctional facility, but to benefit a larger public with the presence of architectural qualities.

The dimension of the station hall’s covering allows for the largest parisian allotment of solar electricity.
