Metro Station 20 designed by StudioATM is part of “Metro Line 1” which connects the center of Sofia with the International Airport.The new Metro Station and public plaza transforms a former local, non urbanized area into an invigorated center. “Metro Station 20” integrates infrastructure and civic space, synthesizing a diverse range of public, retail, commercial and transportation programs . Situated on the eastern part of the Bulgarian capital, between the Sofia International Airport and Tsarigradsko Shose Blvd., (symbolically the main “gate” of Sofia) the adjacent area would become an attractive point for commercial use and communication.
