We are planning to build a two storey extension with hipped roof positioned about 150mm from our neighbour's boundary. The neighbour will not object to planning or party wall notice, but is refusing to allow scaffolding on their side for the build. The owner originally said yes, but a family member has now stepped in and refused permission on their behalf. I've said overhand build won't look so good and scaffolding would allow us to screen off the build with plastic sheeting, and offered a licence fee, but they're not interested.
Several builders advised us that it could be done overhand, but they now say it is very difficult; can't be done for H&S reasons; and would cost heaps more in terms of materials and time. I think the big issue is the roof which would protrude beyond the wall up to the legal boundary line.
Does anyone have a solution? Can a platform be cantilevered over the neighbour's land, or would this be trespass? Any thoughts much appreciated.
