André Tavares is an architect, author of books on architecture and coordinator of Dafne Editora. He was the general curator of the Lisbon Architecture Triennale on The Form of Form in 2016. He begins his article by stating that the old town centres of Lisbon and Porto are full of rubble and waste from demolition and restoration work. What should be a promise for the future actually shows that we are building poorly and for immediate profit on the basis of principles bereft of the old idea of heritage.
