1.The neighbour agrees to use your proposed surveyor. It would be an agreement to use a common surveyor between the two parties. Our recommended surveyor charges $750 plus VAT for each price required. These are the fees for each price, so if several neighbors ask for this, then the fees would go up. If you intend to build a rear extension that includes the construction of a new wall or the junction (the boundary line), the law requires you to provide valid information to your adjacent owner concerned, terminate at least one month before the end and obtain a party contract. If you are an adjacent owner, you may find relief in the fact that Party Wall agreements also contain clauses dealing with the contractor`s work schedules. Indeed, the Party Walls Act of 1996 states that “a distinction may determine the time and manner in which each work is performed.” The first provision of Section 6 includes excavations within a radius of 3 metres, measured horizontally from your nearby building or building. If you indicate whether part of your search at this distance will be deeper than the lower part of your neighbouring building or your neighbouring structure, you are again required by law to serve them with a valid notice of resignation that gives at least one month`s notice and to obtain a contract contract. Now that the party mason has determined whether the proposed extension under the 1996 Party Walls Act is possible, the next step would be to serve the instructions on the party walls. On this week`s blog, I will discuss whether a contractor doing the construction work should follow the party wall procedures, including the execution of a communication on party walls and perhaps a party wall award for the expansion of his land. A party wall message should be sent to your neighbours to inform them of the work you intend to do on the party wall, between two months and a year before the work begins. In many cases, people find that they do not need the services of a party surveyor.
