After the first section of the dome was completed, Layetana placed big ads on the facade.
There are 4.400 windows in the building.
The workers needed 5 days to complete every floor of the striking tower.
Some of the pieces of the brie-solei, in the south facade, have photovoltaic plates to generate electricity for the building.
During the construction, the central core was always one floor higher than the external wall.
The brie-soleil is built out of 59.619 pieces.
Garnered the 2006 International Highrise Award.
The two main cranes reached 167.60 meters and 156.80 meters.
Torre Agbar is very similar in its shape and size to 30 St Mary Axe in London.
The torre is not in fact circular in plan but is very slightly elliptical.
The building has a multi-coloured skin inspired by Antoni Gaudí.
In the square surrounding the building there are coloured concrete seats with facts about the tower on them.
It was officially inaugurated on 26th September 2005. Among many authorities, the King and the Queen of Spain were also in attendance.
The building features spectacular night illumination. The whole tower is illuminated in yellow, blue, pink and red by 4,500 lights placed over the facade.
North side glass brie-solei pieces are different from the south side ones. The ones in the north side are translucid (but transparent when concrete wall features a window) and the south side ones are transparent.
Agbar sold different buildings where their old offices were established to pay part of this project.
Agbar will occupy only half of the office space of the tower. Initially, a branch of this company, SOREA, has rented the other half of the office space untill they will finish a new building to establish its new headquarters.
Concrete walls are 50 cm. wide at the base and 30 cm. wide on the top. The concrete core inside the building walls are 45 cm. wide at the base and 25 cm. on the top.
Windows made of 92 X 92 cm squares.
Underground levels concrete walls are 60cm wide.
At the end of construction, Layetana Developments temporarily moved their technical office to the second floor of the tower.
