Hi All,
I have a conservatory at the back of the house, approx. 3m x 3m. It is a traditional conservatory, dwarf wall with glass all round, separated from the house by a double glazed external grade sliding door.
I am looking to replace the conservatory and increase it to 4m x 6m, however I will be having the left hand side completely bricked, the right side will be bricked with a window and then across the back I am having 4m wide bi-fold doors.
I will still be keeping the external doors between the house and the new conservatory/room.
Having read around I don't believe I will need planning etc, however will obviously build to building regs. I understand that as I am changing the size of the base I will need to consult building control to ensure stability.
My wife has today spoke to planning and been advised we now need a SAP calc as the total size of the glazing is in excess of 25% of the floor space. I am somewhat confused by this as we are keeping the external door between the house and the new build, so based on the info on the government planning portal we shouldn't need SAP calcs etc.
Can anyone give their experiences or thoughts on this please?
All responses greatly appreciated.
Thanks
