After the digging we poured a concrete floor (no pics: too busy) and started building the inner walls. Double blocked on the side where the pool is coming for extra security and all blocks filled with concrete and iron. If a war breaks out we've got a bomb-proof shelter!

And meet Oystein Johansen, our Norwegian neighbour and friend who offered to help a couple of days. He's got an enormous amount of energy and more experience than we have so we learned a lot from him. Thank you Oystein!
