Notice how they have modified the chimney stacks by adding their own home made bricks and cement rendering.
The chimney pots are wooden and were purchased seperately. They have been painted with Humbrol terracotta enamel and then dry bushed with black to give the "sooty" effect.
The slate roof is the MDF roofing painted with grey car primer.
The ridge roof moulding was also purchased seperately and again painted in terracotta. To enable us to list items here we have to give items a nominal value of 1p, obviously this is NOT FOR SALE.
