It is frequently necessary when constructing a new home or making significant improvements to an existing one. Planning clearance is frequently required to convert a piece of agricultural land into a feasible development site. It may also be needed for work on private roads or buildings. The process of obtaining planning permission is known as "planning regulation". The term refers to all the rules and regulations that must be followed before a building project can be started. If these rules are not followed, then planning permission would not be granted. There are two main types of planning permission: consent and direction. With direction, the local council will usually allow you to start work but refuse to sign off the completed project. You would need to obtain further permission for each new phase of the project. With consent, the entire project is approved in one go; you just need to make sure that you follow all the other guidelines below to avoid any problems arising later on. If you are just making minor changes to an existing house (such as adding bedrooms or bathrooms), then you only need consent from your local council. However, if the change involves renovating or rebuilding part of the house, then you will also need to get planning permission. The reason for this is because parts of the house that remain the same require no further approval while work is being done on other parts of the property.
