For the head office of the ImWind Group, located in a former castle mill that is protected as historic monument, we developed a way-finding system which had to fulfill landmark specifications as well as meeting the requirement of the customers in terms of flexibility. As the company is in a growth phase, any indoor signage needs to be adaptable without much effort. Using the specially developed magnet design, the name and department signs can be replaced in no time. We worked on carefully choosing materials like concrete as well as on the graphic design to make the signage blend with the beautiful historic surroundings.
