Fondation GoodPlanet – Domaine de Longchamp



The architectural design was entrusted to the teams working under the architect Patrick Bouchain, renown for his creations of generous and atypical cultural spaces: the “Lieu Unique” in Nantes and the “Cité de l’immigration”, to name just two. With its minimalistic intervention, the project enhances the architectural beauty and history of the site.

Furthermore, the spaces are laid out and equipped to reduce the environmental impact and ensure accessibility to all: wooden access ramp that doubles as a support for the surrounding vegetation, recovery of furniture for the cinema theatre, choice of simple technologies, careful lay-out of the outdoor areas. The aim is to make the Domain a showcase for common sense that will serve as an example for other buildings.

chloe bodart “More than just architecture, it is a human process in action. Architecture, as I see it, is above all an encounter and a constant dialogue. It is crucial to take human relations as the starting point in order to understand the needs and desires that will shape the philosophy of the site. It is a long process, full of stories and surprises. Alongside the different stakeholders, we are rewriting the new ownership of the building. Chloé Bodart (authorised representative architect and project supervisor).

As part of the renovation works on the domain, the Foundation pledged to conduct a Carbon Footprint© of the construction site and to put in place a global environmentally responsible approach under the ISO 14001 standard.


Our approach: nature at work.

Below are examples of our actions to preserve and reinforce biodiversity:

  • On the site, the use of pesticides and plant health products is prohibited: only organic and natural fertilisers are used.
  • Differentinstallations (hives, insect house, wood pules and totems, nesting boxes), and actions (composting, cutting, adapted management, etc.) are put in place to preserve and enrich the biodiversity of the flora and fauna present (transparent pruning to allow the light to reach the undergrowth)
  • Avocation of better protection: devices for selvedge, clearing, grassland in wetlands and uplands
  • Planting is carried out to reinforce sensitive areasthroughout the year

In addition, the domain favours the use of pre-existing natural materials. Trees cut when diseased are turned into wood chip or offcuts to make natural shelters for fauna (field mice, amphibians, etc.).


Preserving and magnifying: the art of gardening. A site characterised by its diverse species, thanks to the site’s history which saw various periods of planting. The artist-gardener supports natural dynamics and strengthens them through planting that diversifies selvedge, undergrowth and riverbanks. The century-old yews and box trees are pruned to form sculptures that emphasise their posture and shape”. Nicolas Bonnenfant (landscape artist at coloco).


The Regional and Interdepartmental Department for the Environment and Energy (DRIEE) and the City Council Department for Green Spaces oversee the work along with the coloco landscape artists. The reconstruction work will be supplemented by a reforestation strategy.
