Permitted development across the property boundary

[^woody^]

Can an extension be built under PD if part of it will cross a boundary?

Specifically an extension that will include a new party wall astride the boundary.

I've always understood that PD rights can only apply to work wholly within the property boundary, as opposed to formal permission which can be granted for works on other's land. I can't seem to find any reference one way or the other, so wondered if its mentioned in the original or one of the earlier PD statutes or case law?

According not that you cannot breach the boundary.

I think you are right. As far as I know it isn't specifically mentioned, but the act says 'within' the curtilage of a dwellinghouse, so crossing the boundary couldn't be described as within. Having said that the other side also have PD rights. Another way of looking at it is the two sides build half a party wall each, which just happens to be joined together.
