Swiss architects Emanuel Christ (Basel, 1970) and Christoph Gantenbein (St. Gallen, 1971) trained at the Swiss Federal Institute of Technology Zurich (ETH Zurich) and began collaborating shortly after graduating. They are known for their innovative spirit, and in Catalonia for being the architects, along with the firm Harquitectes, of the extensions to the MACBA and the MNAC. Christ & Gantenbein is a large firm with around one hundred architects and numerous projects in Switzerland, France, Germany, China, Norway, and Mexico. They haven't ruled out maintaining an office in Barcelona once the MACBA and MNAC projects are completed. "Barcelona is a great European city. We are very excited and grateful to have the opportunity to work here," they say.
