edouard françois: tour végétale de nantes

paris based practice edouard françois has sent us images of ‘tour végétale de nantes’, a residential structure located in the future eco-neighborhood of prairie-au-duc in nantes, france. composed of commercial and residential programs, the tower looks to reinterpret the experiences and interactions of condominium living.

wavering elliptical balconies surround the 17 storey structure, providing the static unit with a sense of life and movement. defined by its lush green facade, the building is layered with thin metal tubes that support a collection of plants grown by the local botanical garden. the containers – which measure 12cm in diameter and 4 meters in length – will be dispersed along the terrace railings, and are thought to successfully recreate the natural conditions of the chasmophyte vegetation.


this is not the first time françois has integrated vegetation into his projects. for more, see designboom’s article on ‘edenbio‘, completed in 2009.

  • it’s like a parking lot with this fence

  • maybe trees are planted in these metallic pillars that would contain some volume of soil and they are perforated @ bottom for drainage which irrigates the grass also ? 🙂

    for the grass its easy u can use the hydroponics technic and plant it in 25 cm substrate only .. but definitely when it comes to automated irrigation system it is a challenging project

    not bad!! 🙂

  • A promising idea. The proceeding comments are correct in assuming that the root/soil depth is underestimated in these renderings but small trees as they are showing (again depending on species) really only need about 5 feet of depth since their roots would adapt and grow out horizontally to accommodate.
    Jean Nouvel NYC managed to integrate small trees in floating cubes within the overhanging outdoor structure. And those seem to be not only surviving but flourishing. I pass them every day.

    Very much possible.

  • How plants can grow up?

  • Chasmophyte plants grow in the crevices and along the faces of rocks. They are very adaptable are are generally able to sustain themselves with limited resources (water, little to no soil, etc.)

  • maybe they are plastic trees? 🙂

  • This firm apparently has no clue that trees are more than trunks and leaves. The space required to support that much soil, to facilitate root growth, would result in an entirely different looking building.

  • mais dans quoi ils poussent les arbres?

  • recently there have been a lot of “tree-tower”-projects… noone keeps in mind that trees also have roots that need a LOT of space! and who is supposed to maintain the trees? the tower gardener?
