In partnership with Bouygues Immobilier Polska, Karmar was responsible for the construction of the head office of Orange Polska. The aim was to facilitate cooperation between the 3,300 employees, who had previously been spread over three separate sites. The head office has been designed as five buildings connected together by an interior gallery. Designed according to the principles of sustainable construction, the site was awarded BREEAM^® Very Good certification at the design stage. The complex is now recognised as one of the most high-performance buildings in Poland.
