Essonne shows a growth in the business real estate sector that exceeds the Île-de-France average since 2018, driven by the dynamics of the Saclay plateau. Some municipalities, once limited to residential activity, are now recording yields above 5% on tertiary assets.
Unlike other technological hubs, vacancy rates are not rising despite the increase in new offerings. Several recent leases illustrate a renewed interest in adaptable, scalable spaces, and small areas. This demand, driven by the arrival of companies from research or deeptech, is becoming increasingly tangible.
