The stairs end has been worked upon. First adding the large upstairs wooden door which was built from scraps of green foam and detailed with more green foam and plastic card.
The blank for the stairs was built from eleven separate layers of 5mm thick foam underlay material that was cut into layers and then glued together with superglue. After the former was sanded smooth I added a thin layer of DAS modelling clay and began the process of carving the stone blocks.
For most of the modelling the steps were kept separate from the building but once I was happy with the progress I glued them in place and started to fill in any gaps with more DAS and thinned filler.
