The tube station is situated in an undeveloped suburban district, at the junction of several main roads. Its construction gave rise to the creation of a development scheme, including a building with an area of 10 000m2 to be erected above the underground station. Its main hall was also to serve as an entrance to the station below.

The juxtaposition of the two geometries (angle of the tracks in relation to the orthogonal grid of the building) has lead to the elaboration of a structure comprised of crossed arches and vaults, which allow the loads to be transferred from the projected building above. The architectural proposal is thereby dictated by the technical constraints of the structure. Walls, columns and vaults are constituted of exposed concrete, according to a geometry that optimises the loads to be transmitted from the ground level to the station below.

Each of the elements (shafts, chapters, arches, vaults) has been devised following the manufacturing techniques employed (metal shuttering, in situ concrete casting, prefabricated vaults). The architecture is thereby perfectly in tune with the materials used, in turn determined by the proposal’s “cryptic” nature.
