Collaboration of Katy Müller and Nathanaël Gourdin in 2003 leads to the foundation of Gourdin & Müller office in 2006. Gourdin & Müller is at the interface of urban space, architecture, product and graphic design information, guidance and orientation systems can impart more than information. The office’s conceptual approach enables the creation of unusual responses, reflecting place, theme or client, i.e. a specific context, which is also represented appropriately. The adequate interaction among materiality, form, graphics and typography facilitates the realisation of identity-promoting solutions. In addition, user friendliness, the representation of complex content and the heritage conservation aspects taken into account form the focus of its considerations. Sophisticated design and a high degree of functionality make signage systems a key communication instrument for companies and institutions. Gourdin & Müller plans signage systems from conception to realisation, accompanying all project phases with the greatest of care and attention.
