The Metropolitan METRO Railways is probably the most important construction project in the city of Athens during the last 15 years. We constructed the landscape area of Nomismatokopoio, Cholargos and Agia Paraskeui Metro Stations. We formed the environmental site of the stations by constructing the automatic irrigation system for the plants and the lawn grass in these stations, in a way that is more friendly and  accessible to the passengers. We also installed the pavements and the wooden benches that exist in the stations. All these constructions extend to an overall surface of 30.000 m2.
