Reflecting the dynamism of recent years, Val d'Oise now boasts a diversified range of office facilities. In the last two years alone, work on 100.000 sq. m. of new office space has got underway, with the focus of development now expanding beyond the Cergy-Pontoise area into the Vallée de Montmorency and other areas: renovation and new construction are reshaping economic life in Vald'Oise.
The east of the département, with its vigourous economy underpinned by the Roissy Charles de Gaulle airport, the TGV ( SNCF high speed train), and the RER express rail link to Paris, has drawn particular attention from real-estate promoters, investors ansconsultants, and this is reflected in the number of offices and technology or business parks. Established centers like Roissy , Sarcelles, Garges-les-Gonnesse, Gonesse, Goussainville and Louvres will soon be joined by others such as Saint-Witz and Vémars -testifying to the département's appeal in terms of geographical position, proximity to Paris and pricing.
