To enclose the property, a huge park "Espace Boisé Classé" surrounds the property.

In the centre, the island with its lakes and its grasslands, surrounded by riverine vegetation, forms a listed wooded area.

Once part of the Versailles forest estate, the parklands are set in the midst of a listed wooded area which constitutes an outstanding plant heritage.

A part of the plot is classified as a Classified Wooded Area (EBC) by its fauna (the pond with a protected toad) and its flora (a plane tree and a line of remarkable lime trees).

The plant, whose architectural structure fits perfectly between the Seine and the protected wooded space of the forest of Fontainebleau, is a genuine biodiversity reserve.

During the works, care was taken to preserve the flora and fauna around the Viaduct and the classified wooded area and the wetlands.
