Suburban Transformations, Building the Metropolis with its Inhabitants 

Suburban areas are the product of democratization of ownership during unprecedented urban growth in the 20th Century. They now take up the majority of developed areas in the Greater Paris region.

Property scarcity is one of the main problems when it comes to building new housing and the hike of real estate prices. This exhibition/research explores the untapped potential of suburban areas for the development of another housing production model based on a domestic scale. 

A recipient of the Pavillon de l’Arsenal-launched FAIRE program, the team behind iudo led a pilot project in Arcueil, a Paris suburb, to experiment around the evolution of individual housing. Eight property owners have been selected through a communication campaign. Each project is the result of a collaboration with the inhabitants, iudo, its partners and eight architecture firms. Led by the common will to shape a new future for the Greater Paris area, each project is an answer to the new needs of inhabitants and is a meeting point between individual stories and a collective future. Intergenerational accommodation, a home for young workers, student housing, office areas or family homes are part of the latest programs creating a new urban dynamic that is aimed at opening up different ways of thinking about the future of the Greater Paris area.
The results of this experiment were presented at the Pavillon de l'Arsenal from December 14, 2018 to January 27, 2019 as part of the exhibition "Suburban Transformations". The eight proposed projects are for the most part under study and the first building permits should soon be filed.

The genesis of the IUDo project stems from an observation: the current models for production in the city are no longer in sync with a significant part of  the metropolitan reality. If we look at the state of the Grand Paris metropolis, the combination of data from the IUA and Insee indicates that more than 80 % of the land surfaces dedicated to housing are occupied by suburban material, which only account for 28 % of the housing stock within the Ile-de-France. Its accumulated surface covers 947km2, more than nine times the surface of Inner Paris. Characterized by a multitude of small private plots of land, suburban material are characteristic of the 20th century’s urban development. Their development was linked to a democratization of new transport systems (train and automobile), younger demographics (baby boomers), a rapidly expanding economy, as well as an emergence of consumer society enabling greater numbers to access credit.

Henceforth, on the urban plan, the city of tomorrow will no longer be based on urban expansion but on recycling. If the urban sprawl is beginning to slow down in the Ile-de-France, the slump in housing offers encourages a rethinking of the models of production still based today on processes of classic real-estate development and mass operations. The effort to mobilize property owners, now rare and precious in urban development zones or free markets, this constitutes up to 50 % of the cost price of the operations according to the regional monitoring centre for property owners.

Suburban material is not often considered as potential territories: the fragmented units are too small, urban regulations limit construction size, thus restricting the profitability of developers’ operations. The multitude of owners and their attachment to their land (88 % of people living in detached houses own their property) renders complex the consolidation of land holdings.

For IUDo, it is not the city that should adapt to real estate but real estate that should adapt to the city. Suburban densification is not simply a matter of ecological necessity but assumes a social dimension and general interest as a vector for a new economy. In the continuity of lengthy research about suburbia, which focused mainly on the Japanese urban system, the IUDo team proposes a new model for real estate production based on the domestic scale. Convinced that the future of the metropolis will be created with millions of small property owners, they think that the economic, demographic and cultural situation is favorable to the changes and to the appearance of new modes of creating. The ageing of the population, relevant to suburbia (86 % of the owners of detached houses are over 40, 52 % are over 55), the emergence of new needs and the growth of the collaborative economy are three pillars that the system, set up by the start-up IUDo, rely on.

By addressing the millions of owners of detached houses, the users and investors through a targeted and operational system, IUDo’s aim is to open a new collaborative network for real estate production, to transform suburbia and make it the material of the metropolis of tomorrow.
Project realized by Benjamin Aubry, Erwan Bonduelle & Yves Lesteven

Benjamin Aubry
Qualified architect and town planner, 2011 graduate of ENSA Versailles. Benjamin is the author of several studies and manifestoes on the suburbia, convinced that it can be the source of new urban and architectural approaches. This interest led him to study and work in Japan, as well as to introduce and to co-manage the Franco-Japanese "Kenchiku Architecture" exchange that gave rise to an exhibition at the Pavillon de l’Arsenal in 2013. After 5 years experience in town planning within the AUC agency, early 2016, he decided to create the start-up IUDo. Persuaded that new means of action pass by entrepreneurship, he is the leader of the team of IUDo.

Erwan Bonduelle

Qualified architect and town planner, graduate of 2007 ENSA Versailles, Erwan worked for over 4 years as project manager on project management within agencies in Paris. Before establishing his own structure - EBA - in 2015, he co-ran GRAU agency, prize winner of the Award for young town planners in 2016. With solid experience in project management, his path enables him to tackle an array of architectural projects on a wide scale. He contributes to the development of IUDo across the board, concerned with architectural processes and project management.

Yves Lesteven

Graduate of the École Centrale Paris in 2011, Yves forged his experience with leaders in the real estate, such as Unibail Rodamco and the Apsys group. At 29, he is a project director and deals daily with the financial, legal, commercial, technical and political problems encountered from beginning to end of a large-scale real estate project. This expertise allows him to provide IUDo with precious, operational and strategic knowledge. Passionate about architecture and innovation, he was instantly drawn to this visionary project.
