Swiss architecture practice, Boltshauser Architekten, recently won an international competition to design a new aquarium in the center of Basel, Switzerland. Their concept, titled ‘Seacliff’, was noted by jury members as being the best match for the public image cultivated by the Basel Zoo. The above-ground building space proposed by Boltshauser was smaller than any of the other competition entries, offering the best solution from an urban development perspective. Beating out such prominent firms as Zaha Hadid Architects, David Chipperfield Architects, and Caruso St John Architects, Boltshauser’s winning project is due for completion in 2019 with an estimated cost of £54 million.
