In recent years, largely as a result of the opening of the second metro line we have witnessed the emergence of a new office zone in Warsaw. The City Centre West (CCW) is located just west of the established Warsaw CBD, where the administrative Wola districts starts. Occupying just over 2.5 sq km of the city, the CCW contains more than half a million sq m of office space and is larger than most of the office markets in the regional cities in Poland. At the end of 2016 around 25% of all of the space under construction in Warsaw was located just in the CCW.
