around the European district (24% in the Flemish Region and 11% in the Walloon Region). Half of civil servants are home owners. The "international community" in Brussels numbers at least 70,000 people. The institutions draw in, directly employed and employed by representatives, 50,000 people to work in the city. A further 20,000 people are working in Brussels due to the presence of the institutions (generating €2 billion a year) and 2000 foreign companies drawn into the city employ 80,000 multilingual locals. In Brussels, there are of occupied office space; half of this is taken up by the EU institutions alone, accounting for a quarter of available office space in the city. The majority of EU office space is concentrated in the Leopold Quarter. Running costs of the EU institutions total €2 billion a year, half of which benefit Brussels directly, and a further €0.8 billion come from the expenses of diplomats, journalists, etc. Business tourism in the city generates 2.2 million annual hotel room nights. There are thirty international schools (15,000 pupils run by 2000 employees) costing €99 million a year. However, there is considerable division between the two communities, with local Brussels residents feeling excluded from the European Quarter (a "white collar ghetto").

This is in part down to that many expatriates in Brussels stay for short periods only and do not always learn the local languages (supplanted by English/Globish), remaining in expatriate communities and sending their children to European Schools, rather than local Belgian ones. Future Rebuilding In September 2007, then-Commissioner for Administrative Affairs, Siim Kallas, together with then-Minister-President of the Brussels-Capital Region, Charles Picqué, unveiled plans for rebuilding the district. It would involve new buildings ( of new office space) but also more efficient use of existing space. This is primarily through replacing numerous smaller buildings with fewer, larger, buildings. In March 2009, a French-Belgian-British team led by the French architect Christian de Portzamparc won a competition to redesign the Rue de la Loi between Maalbeek/Maelbeek Garden and the Résidence Palace in the east to the Small Ring in the west. Siim Kallas stated that the project, which would be put into action over a few a long period rather than all at once, would create a "symbolic area for the EU institutions" giving "body and soul to the European political project" and providing
