would be the / (for events and festivities). Wider development may also surround Cinquantenaire Park with plans for a new metro station, underground car park and the "Europeanisation" of part of the Cinquantenaire complex with a "socio-cultural facility". It is possible that the Council may have to move to this area from the Europa building for security reasons. Further quarters The concentration of offices in the European Quarter has led to increase real estate prices due to the increased demand and reduced space. In response to this problem, the commission has, since 2004, begun decentralising across the city to areas such as the / in Auderghem and the / in Evere. This has reduced price increases but it is still one of the most expensive areas in the city (€295/m2, compared to €196/m2 on average). Neither the Parliament nor the Council have followed suit, however, and the policy of decentralisation is unpopular among the commission's staff. Nevertheless, the Commission intends to develop two or three large "poles" outside the quarter, each greater than . The Heysel/Heizel Plateau has been proposed as one of the new poles by the City of Brussels, which intends to develop the area as an international district regardless. The park, built around the Atomium landmark, already hosts a European School, has the largest parking facilities in Belgium, a metro station, an exhibition centre and the Mini-Europe miniature park. The city intends to build an international conference centre with 3,500 seats and an "important commercial centre." The commission will respond to the proposal in the first half of 2009. As for the existing Beaulieu pole, which is to the south east of the European Quarter, there is a proposal to link it with the main quarter by covering the railway lines between Beaulieu and the European Parliament (the esplanade of which sits on top of Brussels-Luxembourg Station). Traffic on the lines is expected to increase creating environmental problems that would be solved by covering the lines. The surface would then be covered by flagstones, in the same manner as the Parliament's esplanade, to create a pedestrian/cyclist path between the two districts. The plan proposes that this "promenade of Europeans" of be divided into areas dedicated to each of the member states. Political status Belgium operates a complex federal system and is divided into three regions, with the Brussels-Capital Region being an independent region, alongside Flanders and Wallonia.
