Either my whole estate is old world repurposed buildings or all of them have had two to four new layers of bricks just under where the roofs start,it appears they are all repurposed and they put new roofs,i have 10 air vents just on my back wall outside,which i dont believe was originally air vents ,has anyone else noticed this,am i overthinking this or could it be true.Every house has the same new brickwork just under the roofs ,like they levelled them off after destroying the tops,is it possible you think?
