Loft Conversion Crawley & Party Wall Agreements

You are likely to need a party wall agreement if your loft conversion includes:
- Inserting steel beams into a shared wall
- Cutting into the party wall to support new structures
- Removing a chimney breast attached to a shared wall
- Raising or altering the party wall (e.g. for a dormer extension)
These types of work are considered notifiable under the Act, meaning you must inform your neighbour in advance.
When Is It NOT Required?
You typically won’t need a party wall agreement if:
