Question to the Foreign, Commonwealth & Development Office:

To ask Her Majesty's Government when the decision was taken to construct the new NATO headquarters building in Brussels; when any plans for the new headquarters building were approved; what was the anticipated cost of the project at that time; whether those costs have been revised subsequently, and if so, what is the current estimated cost on completion; what the anticipated dates of completion and occupation were at the time of approval; whether those dates have been revised subsequently; and when it is expected that the old NATO headquarters building will be vacated.

At the 1999 Washington Summit, NATO Heads of State and Government decided to build a new NATO headquarters to meet the requirements of the Alliance in the twenty first century. In 2003, the North Atlantic Council approved a design for the new headquarters with an estimated cost of €1.2 billion. These costs have been revised on a number of occasions; the current estimate is €1.17 billion. Handover of the site was originally planned for August 2015 but was delayed until March 2017 due to technical difficulties. Allies will begin moving to the new headquarters in March 2018 with the site of the current buildings returning to the Belgian Government towards the end of this year.
