Triangle building

Previously there were a number of architecturally diverse buildings on the property, collectively named JECL after the initials of the three surrounding streets: Avenue de la Joyeuse Entrée, Avenue de Cortenbergh and Rue de la Loi.

When it was decided that the old JECL complex was to be demolished, the European Commission signalled its interest in purchasing the property in order to build a new EU conference centre on the site. The negotiations between AXA and the Commission were tough and lasted for more than five years, but eventually failed in 2006 due to disagreement over the price. AXA instead decided to built an ordinary office building.

The main structure of the present triangular building was completed in 2009. Referred to as The Capital by Axa, the building was originally divided into 6 technically independent sections named after the capitals of the six founding member states of the European Union (EU): Rome, Paris, Berlin, Luxembourg, Amsterdam and Brussels, respectively. In the centre is a large circular courtyard which is heavily planted and, in 30 years from its construction, the architect insisted it will look "magnificent".[2][3]

Axa intended to split the complex between the Commission, national embassies and private companies. However the Commission refused to share the building. Negotiations became drawn out but as of August 2010 the Commission and Axa were close to a signature for the whole building. In July 2010 European Personnel Selection Office (EPSO) entered one of the six parts of the buildings, occupying 9000m² out of a total of 54000m². It was later joined by the Foreign Policy Instruments Service (FPI) and the EEAS, whose staff had previously been dispersed across six buildings. [2]
