5. Neighbouring properties / party walls
Any building works within 6 metres of a neighbouring home's foundation or to an existing party wall may require you to notify the owner of that property of your intentions, at least one month before you start work.
Work to an existing party wall requires you to give at least two months notice of your intentions. If consent to carry out the work cannot be reached procedures dealing with any dispute should be followed (Party Wall Act 1996).
