Poland

1st Floor is the biggest concrete indoor DIY spot in Poland and probably in whole Europe (*see editors note at bottom). It is located in Lublin, a city in the eastern part of Poland. The history of 1st Floor started in the autumn of 2010, when local skaters cleaned up part of an abandoned building, in order to have a place to skate in the winter time. Jacek Harasimiuk, a local skater, put a bunch of photos from that day on his blog.
