I love this tower design in Montpellier, France. Those decks are made to chill out and drink vermouth in the summer, but I can imagine flying bikes and cars taking flaying in and out, like launching/landing platforms.
Its architects—Sou Fujimoto Architects, Nicolas Laisné Associés and Manal Rachdi Oxo architects—say this 17-story multipurpose tower is "inspired by the city's tradition of outdoor living and the efficient properties of a tree." That's why they call it the L'Arbre Blanc, the white tree. It's been designed to have "apartments, a restaurant, an art gallery, offices, a bar with a panoramic view and a common area."
