✔️ Integrate a school inside a park, rather than proposing a park adjacent to a school.
✔️ Transform an industrial plot without any vegetation into a hilly and flourishing landscaped park.
✔️ Juggle between outdoor spaces reserved primarily for students and those open to the public.
This project is located in the Pont-Rouge district of Lancy, in the canton of Geneva. Developed over the last ten years, this eco-district close to the Geneva PAV (Praille Acacias Vernets) project is an area undergoing rapid urban change.
The plot, a former CCF warehouse, is the last link in this new residential area. Bordered on one side by the railway tracks and on the other by the town hall park, the idea is to create a green extension into which the school fits. Special feature of the project: apart from the valley created upstream, there was nothing existing! It's up to us to shape a green urban park from a blank canvas.
Transform a former industrial warehouse into a lush wooded park
The particularity of the site is to be located in the heart of a rapidly developing district. The initial competition involved half a school group. During the project, the town of Lancy preferred to opt for a complete school group in order to anticipate future needs. The outdoor spaces are used primarily by the school's students, but are freely accessible to all residents of the neighborhood outside of school hours.
The challenge was significant: transforming this former CCF storage area into a green setting to accommodate a school and its courtyard, a public park and a multi-sport area. The land has been completely sculpted to create hills and more than a hundred trees planted to recreate the typical atmosphere of a park.
The plant palette, richer than usual, also transcribes this atmosphere with exotic species, including a ginkgo biloba, a Persian parrotie and particular oaks. For the groves, we worked with around twenty native species, compared to five to ten in a classic project of this scale. To accompany the tree line in the western part, we created an atmosphere under the woods with various perennial plants. The idea is to diversify the species to rediscover the arboretum spirit of the parks. Furthermore, all of the specimens planted, more than a hundred, respect the town hall's desire for organic production.
Within the school establishment, two particular elements should be noted: a “Jurassic” patio and a roof terrace with a view. Located in the heart of the building, the patio takes up the analogy of Australian canyons with rare exotic tree species dating back to the Cretaceous period and exuberant foliage evoking Jurassic landscapes in the collective unconscious. The fun terrace upstairs opens up a clear view of the surrounding mountain ranges. In addition to the panorama, it offers two large wooden vegetable gardens to encourage students to put their hands in the earth during botany lessons.
The bias: integrating a school in the heart of a landscaped park
Focus on: custom-made solid wood benches
A generous public park, a link between the urban and the green
