According to a study by Arthur Loyd, exclusively available to Business Immo, regional office rental markets have changed dimension in 25 years. "If we look at the historical figures for take-up in the regions, at the beginning of the 2000s the level did not exceed one million m² per year. Today, 1.8 million m² are registered in the 28 markets we analyzed. And this process of tertiarization, driven by the combined effect of the 'decentralization' of French economic activity and the buoyant development of regional metropolises, does not yet appear to be complete", asserts the commercial real estate consultancy.
