The few pictures that I do have show some of the clever techniques used by John at Scalescenes, the designer of all of the kits I use.
As you saw in the previous post, the carcass is as simple as it gets, but that's when the clever stuff starts.
The back wall of the house is in three sections. The first part takes two windows and also forms the interior wall of the downstairs scullery. The second takes a window and a door.
When constructing the end gable wall, this forms the end for two houses. It also accommodates a clever feature forming the drainpipes. Constructing them like this means, that they will never be knocked off or damaged. Plus it also give strength and rigidity to the structure.
