The Migros supermarket branch in Zurich’s main railway station is one of the highest-turnover per square metre in Europe. 12,000 to 15,000 people come and go here every day, 365 days a year. As part of the refurbishment, the Migros Cooperative Zurich is relying on Aroma for the new concept, the realisation and the interior fittings. “The biggest challenge was to achieve the maximum for the customers and their quality of stay during the given short renovation period with minimal interventions,” says Yves Thommen, Head of Architecture and Creative Director.
