Whilst the criteria set down in the design competition specified the first Jean Monnet building remaining occupied during the construction of the first phase of the new complex, the 2014 discovery of airborne traces of asbestos in the original building led the Commission to begin transferring staff off premises in late 2014, relocating them to other additional office premises in the Gare and Gasperich quarters of the city, and a temporary building constructed opposite the old Jean Monnet building in Kirchberg in 2016 by the Luxembourg government.
