Hallo, Master,
I need your help!
We bought an appartment, which is built in 1980 (period 6). The previous owner has made a change and I wonder is this change big enough the appartment to become period 7 and reflect to my Flying Star calculations. A door to balcony was walled up and the balcony bacame a opened kitchen to another room. I attach here a drawing.
or the appartment considered to be period 8 because we are now moving in
