French designer Pierre Cardin has unveiled a plan to build a $3bn Palais Lumiere tower in the industrial port area of Marghera on Venice lagoon in Italy.
The 255m tower in Porto Marghera would rise on a 40ha lot occupied by warehouses, which would first have to be cleaned of industrial chemicals.
The 65-storey tower will feature three similar fin-shaped towers of different heights connected by six disc-shaped structures.
The three towers will be positioned around an open central area that will house 21 lifts to offer direct access to large circular floors, which could be used for commercial and recreational purpose.
The building’s six discs will feature over 4ha of hanging gardens, as well as public and private ponds and swimming pools. There will be a helipad on the roof.
The six circular floors are spaced 40m apart and have a lens shaped cross section to optimise aerodynamics and limit wind pressure on the structure.
The complex will feature apartments ranging from 50m² to 400m², a hotel, office and commercial space, a conference centre, a shopping centre and restaurants.
The underground level will feature over 4,000 parking spaces and garages as well as the geothermal air conditioning plant.
Cardin, who designed the building with the help of architect Rodrigo Basilicati, said, "I want to offer Venice a big garden for eternity."
The project is expected to complete in time for the Milan Expo in 2015.
