So, we are in the middle of a load of building work.
The 1st major for us, but the 3rd for the house.
A minor part of our work with planning approval is adding a porch to the front of the house (2.85m * 1.6m ext, 2.25m*1.3m int).
Does anyone know if I need to get new planing approval (or modified on a 2.5 yr old approval) to go up from that porch to a 2nd storey to extend the front box bedroom, or can it be done within permissive dev.
No change to footprint will occur.
