Your Loft Conversion And the Party Wall Agreement Home extensions, such as loft conversions, that fall under the Party Wall Agreement require you to notify your neighbours in writing of your plans before commencing work. Therefore, if you live in a semi detached or terraced house, it is likely that in the process of converting your loft you will need to work on a wall shared with a neighbour.
For example, you would need to serve a party wall notice to the adjoining owners if you decide to extend your wall vertically on the boundary line to build a dormer roof extension. In this case, you will need to get your adjoining neighbours’ permission first (usually at least two months in advance), and a loft conversion company in London can advise you on this matter. Why you need it Failing to do so entitles your neighbours to seek a court injunction to stop or schedule your work at certain times. However, for a loft conversion in a detached house, you won’t need a party wall notice, unless you need to re-enforce your foundations (then you will need an excavation notice). A party wall notice can be downloaded from the governmental website, and can help you solve any disputes that may arise. It also describes your rights, such as convert your loft, increase the thickness and the height of the party wall, demolish and re-build it, as well as place a flashing between two adjoining walls in order to protect them even if you have to cut into the walls of an adjoining owner.
