Lex building

The Lex building is an administrative structure in Brussels' European Quarter with 15 above-ground and 5 underground levels. Glass facades allow abundant natural light throughout the interior spaces and the structure contains extensive office areas and meeting rooms.

Construction was completed in 2006 after the European Union needed extra office space following the 2004 expansion. The building supplemented the existing Justus Lipsius building, which had reached its capacity limits.

The building houses thousands of EU officials and diplomats who work daily on European policies and decisions. The spaces are designed to support international collaboration and exchange between different nations.

The building sits at 145 Rue de la Loi and has direct connections to nearby metro stations. A restaurant on the ground floor serves both employees and visitors.

The structure contains two deliberately empty floors designed for open spatial planning, which is an unusual feature of modern architecture. These vacant levels allow flexible air circulation and space usage throughout the building.
