The project is part of the Balma-Gramont concerted development area (ZAC) on the outskirts of Toulouse.
On the outskirts of Toulouse, there is a plot of land by a hillside with a marked topography, offering wide views of the surrounding urban landscape below. The planning approach is to install a tiered landscape associated with the waterway, making a recreational and practical ‘valley’ in the heart of the urban area.
The project is characterised by three landscapes:
- The terrace. Located above a semi-underground car park, this garden esplanade, at the foot of the housing, is a convivial shared space with a vegetable garden available for everyone to use.
- The terraced slopes. A place to relax, next to the housing by the slope. Wide meadows unfurl over these terraces, shaded by alleys of fruit trees. Gabions sit at the foot of these stone terraces, helping to guide the rainwater, dispersing it around the paths into the soil.
- The gravel valley. Located at a low point, at the foot of the terraces, it is a major link between the various project spaces. Connecting the housing and commercial properties, this strip of landscape is hollow, fluctuating according to the rhythm of seasonal rain showers.
A blue frame work echoes the green framework of the terraces and orchards. Gravel rain gardens guide and filter the rainwater from all over the project site. The bottom of the valley is designed as a mineral esplanade lacerated with planting beds. This vegetation creates a filter between the public space and the buildings whilst still maintaining easy access. Next to the offices, these filtered spaces form separate rooms with furniture to sit, lunch and rest.
