“Place des Alliés” was transformed into an ideal meeting place for locals; a nice place to meet, chat, visit a market or throw a party, complete with a large underground public car park for 180 parking spaces, keeping the upper level of the square free from cars.


The project includes the following technical installations:

  • an integral sprinkler system
  • a network of fire hydrants
  • Mechanical ventilation with an air extraction unit perfectly integrated with the concept of the square
  • LED lighting for the interior car park
  • outdoor lighting of the square on light masts
  • a hydrocarbon separator for wastewater
  • two energy terminals on the square
