We have a double door (without a letter box slot) which is made of steel and covered in wood and have about another 0.5m wall either side of it.
If I don't want an externally mounted key operated letter box to be stuck to the wall to the side of the door how would I create a letter box opening in the wall to accommodate a cavity wall and then come inside the house? Is it possible ie what about the inner bits?
