I have just drawn up plans for a single story rear extension on my 3 bed semi. Sadly my neighbour died recently and I have learned that the property is on probate. In the mean time I have served a "line of junction notice - new wall astride the boundary" using the example letter 4 available from the Ministry of Housing, Communities & Local Government website. Since I don't know who the new owner is I addressed it to the "Home Owner" and handed it to the deceased sister-in-law, who will be sending it to the next of kin. Under the present situation, I would not expect to get any response to this any time soon. The notice that I served states that in the event of "No Consent", (and as per my plans) I will build the new wall wholly on my land and up to the boundary line after the notice period for a response has lapsed. I do intend to appoint a Party Wall Surveyor for this, but before I do that I wanted to ask the question here, to try and get some information as to when I can expect to start the work.
So my question is, after I have appointed the surveyor, can I start the work ? or will I have to wait till the property ownership gets resolved either through the sale of the property or inheritance by a next of kin or by some other means ?
Any advice and information would be most appreciated.
