roundabout

Here is the excavation of both roundhouses taken from the wee hill above the plot. We have since dug out the corridor linking the two round houses and done all the levelling. The finished floor level is almost exactly where the concrete pad is for the 9m roundhouse. The distance taken off the architect's substructure plans between these centres is 15501mm. We have measured our centre points at 15500mm so that's not too bad.
