The investment in the construction of land in France is radically changing. With the application of the Zan law (zero artificialization), the acquisition of plots to build individual houses can become an inaccessible dream for many investors. Discover why these lands, previously symbols of freedom and independence, are becoming a rare and expensive good.

The devastating effect of the Zan law on the construction of land
Since 2021, the climate of resilience has imposed a drastic reduction in the artificialization of soils, aimed at an ambitious objective: achieving «zero net artificialization» by 2050. This goal, known with the acronym Zan, obliges the municipalities to compensate for any new construction by the creation of a natural space of equivalent dimensions. As a result, the Municipalities now hesitate to issue construction permits on new construction land.
This gradual limitation has already visible repercussions on the real estate market. The price of the construction of land continues to rise, making the purchase of these plots increasingly difficult for investors.

In île-de-French, for example, the price increases to 233 euros per square meter, while in Normandy it is 65 euros.

This paradigm change can redefine the French real estate landscape, in particular for the merchants of goods that see in this law a direct threat to their business.
