The existing offices are combined with an salt storage and garages for snowploughs and gritting trucks.
The arrangement of the plot is based on the typology of a farmyard. The different functions are organised around an open court, visible from the office. The starting point of the used materials is the extreme corrosive environment of the salt yard. The substructure is formed by the repetition of a modular prefab concrete element. This plinth frames and delimits the plot.
The roof is presented as a light-footed construction which refers to breaking up ice. The roof covers the robust concrete substructure and seems afloat because of the pronounced contrast in form and material.
