The party wall is either side of a mid terrace property or one side of a semi detached or end of terrace property is owned by all those whose property is connected to it. Because you are planning to do a loft conversion, you have to inform the neighbour about your plans to carry out the project, the neighbour who has a total time limit of eight weeks to get the agreement in place with you. It normally only takes two to three weeks if all parties are working together well and good will prevails!
There are two forms. One is the party wall notice form, used to formerly give your neighbour notice. The other is the acknowledgement form, which your neighbour has to sign and return, with their choice to engage a party wall surveyor or not.
