The Europa building is one of the most recent and magnificent examples of contemporary architecture in Brussels. The enormous cube is made up of 3 750 restored window frames and contains a glass lantern that, at night, is beautifully lit up by 374 LED tubes. This ‘House of the European Member States’, with its multicoloured interior, is the main seat of the European Council and of the Council of the EU, and is where meetings between EU ministers and heads of government are now held.
Philippe Samyn, the Europa building’s lead architect, sees it as the expression of a number of the values espoused by the EU. The façade thus consists of window frames from every EU country which signify both the diversity and the craftsmanship of every Member State, as well as the desire to promote sustainability. Thanks to the collection of rainwater, the use of solar panels across the whole area on the top of the building, and the optimised façade structure, the Europa building has been awarded the Valideo environmental certificate. The interior lantern, built in a shape that was necessary to avoid too much pressure being exerted on the ground and the underground metro tunnels, mainly contains meeting rooms and a large press room and press area.
