Planning Permission

For basement excavation or dig-out (also known as a retrofit basement), planning permission is required, mainly in relation to any means of escapes or light wells that are to be installed. This is because they affect the exterior appearance of the property.

Fortunately, planning permission is almost always granted as it does not change the exterior appearance of the property above pavement level.

Building Regulations

Building regulations will be required if you are changing the use of the basement to habitable living space. This includes the means of escape, the thermal values, etc. If it is simply to be used for storage though, this may not be required.

Many things affect what is required for means of escape, for example, does the basement exit onto a hallway which has a direct route to an exterior hall? Or does it exit into another room? Please contact us and we will be happy to visit and discuss your options.

Party Regulations

A party wall agreement is a legal agreement with your neighbours to commence building work which affects the jointly owned wall between the properties.

There are many myths surrounding party walls agreements and their process. One of the many concerns is that the neighbours will not sign the agreement, effectively blocking the work from taking place.

Project Management

Every client is assigned a project manager at the start of the process. Your project manager will be your main point of contact and will keep you fully involved and informed of progress at every stage of the basement build, working with you to ensure your project runs smoothly.
