Our building control inspector came along this afternoon to take a look our new walls. He was curious about our cement panels and what they were made of and we reassured him that they are made of wood chip mixed in pure cement and compressed into flat 10mm sheets. He also wanted reassurance that we are fire proofing the necessary cladding along the back walls which are the nearest to the boundary line. We said we are already looking into various methods and options.
He had a look inside for a minute or so and that was it!
He was happy and we are happy too!
