The Hangar Designed by God (HDG), with the help of a Dutch architect ran into into a spot of bother...ahem..
The roof had to be raised by 30 cm, otherwise only dwarfs would have been able to use the spiral staircase. It was all sorted before we left,so all is well, and in fact it will make the bar much more impressive, with the added height, so it was probably intended this way after all- who can understand the mysterious ways of God?
