Do I need Planning Permission for a Basement?

Basement Planning Permission Consultants

There are many rules and regulations that apply to creating living space in basements. We have summarised these here with aim to give you clear and definitive answers to your planning queries on Basements.

 

Converting an Existing Basement

If you are converting an existing basement or cellar into living space,  without any exterior alterations, you are most likely not require planning permission.

 

However If the basement is going to be used as a separate unit of residential accommodation it will require full Planning Permission.

 

Similarly, if you intend to incorporate a light well into the design, you will  definitely need planning permission as it alters the external appearance of the property.

 

Creating a New Basement

If you intend to carry out major excavation work to create a new basement, you are likely to require planning permission. This is because you will need to incorporate a light well/wells into the design (Building Regulations) which will demand that you excavate beyond the outline of the existing house to create a light well/wells, thereby requiring Planning Permission.
