Evening all, we have started to dig the foundations for a 3 bay open fronted hay & landrover storage ;-) barn. Its 12m x 5m wide 6m high. Original design was for a standard 45 pitch roof both side.
The lower level will be for hay etc I was thinking of making the upper level more useable for workshop or storage. Thus thinking of changing the back side pitch to a mansard to give me more head hight this is the side that no one can see as it faces in to a forest.
My question is do I need planning consent to change to a mansard (the original roof ridge hight will not change)
I'm located in an ANOB
Thanks in advance
