Students have to describe buildings and building projects to show how architecture reflects the lifestyle of one’s country in the place where they live or nearby through a C.L.I.L. approach. We want to draw attention to the changes in architecture as well as in culture, trying to show both its positive and negative side. After that, they would be able to understand where refurbishment architecture and design, as well as sustainable refurbishment, could be useful. This will lead on to discussions and comparisons between the architecture of the different countries, revealing what is invisible to our eyes.
