To expand my question: I am building a house with modern installations. I know that people who view properties look at the kitchen and garden to make a decision. But can they be convinced that a property is worth more because it has quality materials?
At present I am trying to decide whether to use concrete or clay tiles for the roof. Will estate agents, for instance, point out that if the house has clay tiles they are going to stay looking good much longer than the concrete tiles? If you tell the buyers, will it make any difference to them?
