Planning is about how we plan for, and make decisions about the future of our cities, towns and countryside. Your local planning authority is responsible for deciding whether a development – anything from an extension on a house to a new shopping centre – should go ahead. For example, in most cases, it would probably not be a good idea to apply to build a nightclub or disco next to a retirement home.
However, careful and clever planning combined with sensitive design and landscaping can make some development acceptable where it would previously be thought unsuitable. This is the reason that applications are considered so carefully. The planning system is needed to control development in your area.
