I am married to a Cuban woman and we would like to buy an old house in Cuba. I am interested to find out if we buy a house in a bad condition, can we demolish the house and build a new one on its place. My other questions are: Do we need to ask for a special permission to build a new house? Who can issue such permission? After we build the house, what institution do we turn to legalize the ownership of the new house? Thanks!
