Northern France is not the first place one would think of when looking to find tropical flora and fauna, but thanks to the recently unveiled Tropicalia project, that is exactly what hundreds of thousands of visitors per year will find.

Tropicalia, designed by Coldefy & Associates Architects Urban Planners, will be the world’s largest greenhouse under one roof once completed in Rang-du-Fliers – in Pas-de-Calais. The massive greenhouse will offer an immediate change of scenery to visitors who take the journey along its over one kilometer-long footpath that winds through dozens of animal, tree, and flower species.

The self-sufficient structure produces energy through the use of a double dome that creates a room where air is heated through a greenhouse effect. The building is designed to blend into the surrounding environment and is set partially in the ground to lower its height and impact. Its profile within the landscape is that of a small hill.

Construction of Tropicalia is scheduled for the first semester of 2019 with a planned opening in 2021.
