Modular structures and prefabricated construction elements form the basis for the new office and administration building of the Zug waterworks. The regional energy, water and telecommunications corporation requested a building that spatially reflects and rigorously implements high demands placed on economy, functionality and sustainability. Based on these specifications, the Zurich based office Boltshauser Architekten developed a building volume with strictly organised floor plans – which permit flexible subdivision and adaptation for a diverse set of uses.
