I built a horizontal area at the top of the slip to hold the 'Engine and Winding House'. The carcass of the building is made up of recycled 5mm thick foamboard. I've used this material quite successfully in the past for 1:43 scale buildings. It's a good material onto which I will attach 'Das Pronto' modelling clay before texturing to represent red sandstone. more about that later. Hope you don't think this is too much of a departure from boat modelling.
