Energy label G… or Z?

Today, I opened up the cladding of the wall in the front of the house. Behind the layer of gypsum board, there was a lot of space next to the window frame, which was filled up with… newspapers. Once I removed those, I had a new view onto the street!

This is the door from the hall to the living room, that was covered up by the gypsum boards.
An extra piece of wall in concrete blocks, below the windows in the front.
This piece of wall will have to go also. 🙂
