This house was converted

from a cob barn in the 19th C. It was rendered in recent times with cement render and painted with a modern plastic paint. Both finishes were detaching themselves from the wall, trapping moisture and causing damp problems inside. Both finishes were removed and replaced with a
traditional lime render and a limewash. The walls dried out and the damp within the building dried out.
