4:05 p.m., boulevard du Général d’armée Jean Simon, Paris 13. Two inclined skyscrapers are under construction at the edge of the ring road. Duo (27 and 39 floors) is a large architectural project by Jean Nouvel. “The east of Paris is gradually becoming clearer. (…) Here it is a question of building its summit, its culmination for this beginning of the century. The towers will measure 135 m and 180 m respectively (The Montparnasse tower measures 210 m). They will house accommodation, offices, shops and a 4-star hotel complex signed Philippe Starck. The architect writes: “The towers will dialogue, like two dancers in balance who are concerned about their environment. »Since when do concrete constructions dance and care about their surroundings? The ultimate: sleep or  dine with a breathtaking view of the ring road 🙂
