Clos Saint-Vincent in Blanzat: an ambitious project to redevelop industrial wasteland

Auvergne Habitat, accompanied by the firm Ilot Architecture, undertook the requalification of a 2019th century industrial wasteland, acquired in 78, for the construction of 13.000 housing units. The Clos Saint-Vincent project in Blanzat, which has a land base of XNUMX m², aims to improve and revitalize the entrance to the town of Blanzat while preserving part of the heritage in order also to respond to the low-carbon issue.

In this context, the building of the old paper mill has been preserved and will be rehabilitated in collective housing; the house located at the entrance to the site will be transformed into 2 apartments, a Volvic stone staircase will be preserved and existing structures will be reused to create parking.

Le Clos Saint-Vincent in Blanzat: the sustainable transformation of a XNUMXth century industrial wasteland

This project aligns perfectly with the objectives of the Climate and Resilience law of 2021 which aims to achieve "zero net artificialisation". Indeed, the requalification of a former industrial wasteland into 78 housing units without resorting to new artificialisation contributes to achieving this objective and constitutes an excellent initiative to give new life to an abandoned site.

The choice to keep part of the buildings and transform them into housing or a pocket of parking lots will reduce the carbon footprint of the project. The guarantee of depollution of the site and the appropriate management of demolition waste testify to the serious commitment of Auvergne Habitat and the other stakeholders in favor of the preservation of the environment.

Furthermore, the launch of the wasteland fund recovery plan, which aims to support brownfield land recycling projects, was a crucial step in the realization of this project. Thanks to a successful application, obtaining state support for an amount of 1,6 million euros was decisive in the development and implementation of the project.

This financial aid has therefore made it possible to guarantee the feasibility of this rehabilitation project and significant resources have been implemented to ensure the depollution of the site, the proper management and treatment of demolition waste.

The project is therefore part of a strong environmental approach by limiting urban sprawl through the rehabilitation of an existing site. This commitment to the environment is also reflected in the choice to preserve the reach channeling water located at the heart of the site to exploit hydraulic power.

The creation of an electricity production unit from the hydraulic power available on the site is part of the energy sobriety plan and will make it possible to produce green electricity, corresponding to the average electricity consumption of 11 T3 pavilions. . The benefits of this electricity production will be shared between all the tenants, because it will be injected into the network of the residence, in particular in the common areas.

The 78 housing units financed according to different methods (PLAI, PLUS and PSLA) were built with the aim of promoting social diversity. Indeed, these modes of financing allow tenants in a precarious situation and with moderate incomes to access housing at moderate rents but also to rental accession.

In addition, the diversity of housing types, namely individual, intermediate and collective housing, also contributes to this mix.
