ETIK is a new office development in Boulogne-Billancourt, in the agglomeration of Paris. It accommodates 10.000 m2 of offices and 500 m2 retail facilities on eight storeys above the ground and 150 parking spaces on four underground levels. The design, elaborated by KCAP Architects&Planners in cooperation with local architects Ateliers 115, was awarded first prize in a competition in 2007. Due to its sustainable concept, ETIK has received a dual certification: NF HQE Commercial Building plus the BBC (Batiment Basse Consommation) Effinergie seal of approval. The location of the building, the Ile Seguin-Rives de Seine, is a former industrial area in the West of Paris along the river Seine, previously occupied by Renault automobile production facilities. After closing the factory premises in the early 1990s the 74 ha site is being redeveloped for housing, offices, retail and public facilities with a total of 850.000 m2 for 12.000 people and creating 10.000 new work opportunities.
