If anyone is interested here is my SBS for building a 1:35 scale house.
The dio was based on this painting which I found of the town of La Roche.

So this is how the building at the right was constructed.
From a set of elevations I cut the basic wall sections from 1/4" plywood.

These are then assembled.

I use wood glue and little nails used for pinning rail track to a base board. Window and doors etc are added from wooden lolly sticks and glazed with food packing plastic.

I added the roof from simple cereal box card and then tiled it with card tiles.
Tiles were painted in various grey coloured acrylics and the gutters are added from thin aluminium pie tin bent into shape.

Finally the whole thing was painted with Acrylics and some pastel used for initial weathering.

If anyone has any questions or comments please let me know.
