Is there a legal definition of development?
The legal definition of development includes building and engineering operations and changes to the use of and or buildings. This can include building walls, erecting new buildings, altering buildings, new roads and accesses, conversion of buildings, and demolition. Planning permission may also be required for some business premises and businesses working from home.
Why control development?
Over 140,000 people live in the area and many more visit to work, to shop or for leisure. Because of this, the way any land or building is used or the way a building is designed can affect many people. We have a legal duty to control development so that land and buildings are used sensibly, in a way that is best for the whole community and the environment.
What are the benefits of controlling development?
Some of the benefits of properly controlled development are:
- Ensuring that new houses are connected to roads and sewers, and have shops and schools nearby
- Keeping noisy or dirty industry away from residential areas
- Ensuring that new buildings are well laid out and at home with their surroundings
- Conserving countryside and good farmland
- Ensuring that the road system can handle new developments
