Which rules apply in Willesden?

- Where the building regulations apply to a conversion, Part E sound requirements can apply between rooms and floors.
- Building regulations cover structural changes, new partitions, ensuite drainage, fire-resisting construction and notifiable electrical work.
- A conversion can be a material change of use under the building regulations, so confirm with building control before work starts.
