under - in - above. Defines the relation between a building and an artificial void in the land. It is the artificial adaptation of the building to its environment, to a climate and its energy, to the train and to two pathways, towards nature and industry. It is the cohabitation with water, wind, ground and sun. It is the mass, the exchange, the concrete and the steel: the tectonics and the stereotomics. It is a passive system. It is a stitching of the land. It is an infrastructure: the unification of a park, a station, a few multipurpose spaces and a nature interpretation centre.
