Have just bought a house, and I am about to build an extension onto it (have planning permission for this). The extension isn't close enough to next door to need a party wall award, but the existing brick garden wall between our gardens (which is ours) will need to come down and be rebuilt as a result of our building foundations for the extension.
I am suddenly wondering if I do need a party wall agreement for the wall. Can anyone advise? And does anyone know my other obligations with regard to next door's garden would be - e.g. how much replacing of plants etc will I need to do? I want to do as much as I can just out of neighbourliness, but it would be good to know my obligations, too!
