Schoonmaakbedrijf Westerveld has found its new home in the old Wybertjesfabriek building in Hilversum. The monumental building has been extensively renovated while preserving its old history. The single-glazed Glass-Concept partition consists of slim aluminium frames incorporating triple glass. The glass partitions, heat pumps and air treatment system create a sustainable and energy-efficient office. As a result, the 1050m2 building has been awarded an A++ energy label!
