boltshauser architekten of switzerland has won the bid to design the basel zoo aquarium, beating out prominent architects such as
bernard tschumi, david chipperfield, MVRDV and zaha hadid. their 'seacliff' proposal for the ozeanium was selected for its understated architecture
and compact above-ground building space, as well as its clay and trass lime façade.
'all in all, the entries submitted were at an extremely high level and represented a wide range of interesting proposed solutions for the task
and location at hand', explained jury member and basel canton master builder fritz schumacher. 'however, the restrained architectural language
chosen by the winning project 'seacliff' was the best match for the public image cultivated by basel zoo. under this proposal the above-ground building space on the heuwaage site is smaller than for other competition entries, thus also offering the best solution from an urban development perspective.'

organized entirely above-ground, HHF architekten + burckhardt partner's second place entry 'watergate' is a monolithic slanting structure.
with nine floors, it was the tallest standing of the projects submitted.

third place: 'blue cave' by zaha hadid architects

zaha hadid architect's third place proposal 'blue cave' was highly considered, however, the jury felt that the visitor aisles were relatively narrow
in many areas and the dynamic styling of the interior would have competed too much with the aquariums themselves.

in february 2012, 55 teams bid to construct the basel zoo's aquarium. each one was composed of three parts: an architectural firm,
aquarium designer and a general planner. from there, 15 were chosen to develop a proposal for the 'ozeanium'. the competition jury
was composed of representatives from the cantonal construction and transport department, basel zoo representatives and a number of architects,
deeming 'seacliff' the best fit for the zoo.
construction on the new building is set to commence in 2014, and if all goes as planned, the ozeanium will open its doors to the public in 2019.
here is a look at some of the other proposals:
