destined for land fill, various sheets of ( Yuk) pollystyrene 75 and 100mm thick.
commencing a 9.8 square meter round studio in the next day or two.
looking for readly available round windows, or round skylights that would suit in wall.
and seeking ideas / availbility of copper grindings, to use as a paint like final render coat?
