This project is intended to turn excavated soil into a new raw material that offers a pragmatic and cost-effective solution to the problem of the construction of buildings and outdoor facilities, such as car parks and footpaths, which are often made of concrete or sand-lime mortar.

In order to make sustainable urban densification possible while maintaining an acceptable quality of life, it is essential to rethink the approach and materials used in the design and construction of buildings and facilities. Of the construction waste that is not recovered, excavated soil has the largest volume.

The excavated soil could therefore become:

• the essential component of a new construction and prefabrication technique called shotearth.
• the ingredient that makes many outdoor developments vegetable and self-recyclable.

This project is intended to develop new approaches to the design and construction of buildings using excavated earth, thanks to:

• the use of innovative manufacturing techniques (classic projection, 3-D printing of complex elements).
• the optimisation of materials, combining performance and eco-compatibility.
• the optimisation of form and the link between form and function.
