Gustafson Porter + Bowman's redesign aims to address crowding issues and improve services at the Parisian landmark ahead of the Olympic Games being held in the French capital.
Called One Line, Gustafson Porter + Bowman's vision for the famous landmark is add more greenery to the areas either side of the Eiffel Tower.
One Line will create a green corridor the Palais de Chaillot at the Place du Trocadéro and the École Militaire at the Place Joffre. It will feature an amphitheatre at the Trocadéro and more public space around the Varsovie Fountains.
Pont d'Iéna is going to be turned into a green bridge, and the Champ de Mars will have two new squares and raised lawns.
"One evokes the union of two historic landscape typologies: classical French gardens, characterised by major axes that express power; and French picturesque gardens, as places of artistic experimentation," said Gustafson Porter + Bowman.
"In this urban landscape, green routes and gardens reserved for creative pursuits frame and soften the central axis."
New trees will be planted in One Line's new parks around the Eiffel Tower, to improve the biodiversity of the area. Out of a commitment to tackle the climate crisis, Paris is aiming to hold the most sustainable Olympic Games yet.
The first stage of the One Line project is due to be completed in 2023, in time for the Paris 2024 Olympic Games.
