It is the construction of one of the largest free-standing aircraft hangars, originally built by the German company Cargolifter. After the Cargolifter hangar concept failed, a new use was sought and it was acquired in 2003 by the Malaysian consortium Tanjong PLC/Colin Au. In 2019, the water park changed ownership and since then belongs to the Spanish group Parques Reunidos.

It is the fourth largest building in the world in terms of usable volume, in the interior, it could fit 8 football pitches or the Statue of Liberty standing upright...

The object of this project is the renovation of the exterior cladding of the old mobile hangar doors. It has been decided to remove this mobility.

A structural justification of the solutions applied has been carried out, taking into account the results obtained in the wind tunnel and the analysis of the static calculation studies carried out previously. 

Due to the continuous operation in the building ("Dome"), on-site operations are increasingly required to avoid or reduce all emissions.
