Ok, trying again for traffic....
Does anybody have any idea of when the relaxations to permitted development rights are likely to be implemented? What happens to existing party wall agreements if you specify one design such as a rear extension but ultimately want to build a wraparound (I think these are going to be brought under permitted soon)? Does a party wall agreement necessarily come attached to a specific layout or is it enough to say that you will build in accordance with permitted development rights in force on the date of the build?
I really want (or infact NEED) to get going but I don't want to end up paying out twice for surveyors etc. I don't get on particularly well with the NDN but that isn't a reason not to go ahead.
Finally, could I clarify ... if I do not dig foundations deeper than those dug by them for their ground floor extension then do I even need a party wall agreement?
