The building renovation and extension of the old terminal at Zaventem airport, in order to house the head office of Deloitte, consists of 34,000 square metres of offices spread across four wings, surrounding a large atrium containing trees. This central volume, which is a meeting and gathering area, includes the reception, the company restaurant and a multi-purpose space. It also contains the main vertical circulations. The office floors are designed to offer great flexibility and the possibility of organizing them per floor or per wing. The top floor, benefitting of the view of the airport runways, houses the top management. In cooperation with Jaspers-Eyers Architects.
