In my own country, there are strict laws about where people are allowed to construct new buildings or add to existing ones. There are a number of reasons why many people feel such regulations are a good idea. Firstly, proponents believe that planning guarantees that local resources will be controlled properly. It is important, for example, to decide whether there will be enough water to supply the number of new people moving into the area. Secondly, popular areas such as those with beautiful view might become spoiled if everyone can build there. Related to this is the issue of consistency. In a street with a number of historical houses, for instance, it would be damaging to the character of the area to put up brand new houses or to add e new floor to an old house.
