Tomorrow 150 buildings in the whole metropolitan area of Barcelona will open their doors for the 48h Open House BCN 2013, a project part of de Architecture Festival that started in 2010 with the aim of allowing everybody to experience architecture in all its declinations. Old renovated factories, private apartment, public buildings and even greenhouses will be available during this weekend. Queues are usually very large: my tip is to select few special buildings are be ready very early. Some iconic buildings will be available, such Mies Van Der Rohe's Pavillion, a project by Miralles Tagliabue and some amazing apartments in Raval and Eixample district. Stay tuned in my Instagram to see more!
