“Fòs” is a hydroponic staircase made of modular elements which can be pulled out with a smart opening system. Every single module has a stationary external part and aremovable  internal part that create the step of the staircase. Every step holds two hydroponic led stripes to let the plants grow. They also light up the stairwell because of the glass structure of the riser of the step. The technical compartment consists of a linear actuator and guide lines to open the step and pull out the tray with the plants. 

The drop-down sprinkler system is placed lateral to the trayand works with a hydraulic pump. The chosen name sums up and encompasses the project concept: “Fòs” in Greek means “light”, the most important component of the hydroponic system and because this project wants to light up the staircase without pulling the switch.
