Whether using the space as smart storage, an extra bedroom, an office or even a cinema and games room.

What is the Party Wall Notice?

It is also important to note the Party Wall Agreement when doing a loft conversion.

The Party Wall Agreement is between you and your neighbour which means that the work is done fairly and doesn't harm your neighbour's property. 

A Party Wall Notice will need to be handed over to your neighbour, breaking down your plans, which your neighbour needs to sign.
