TRADITIONAL WOODEN HOUSE BUILDING

I've got one big order from an association for local traditional values to build model of wooden, old, local, traditional house to be built up by kids on local fairs, so they can learn about traditional house building from past.
Total size is 160x110x160cm.
Main condition was to make foldable walls for that purpose. Only roof was permanently assembled as one single whole and it is to put it on top at the end of building walls.
Main elements of that trditional building was : overlaping corners, wooden dovels joynery and sequence marking of every piece of wood for assembly. As you see, I kind of recreate all those lements, adjusted to kids building.
For making that house I used fir wood 4x10cm planks. For roof base, there is 10mm thick OSB board and roof tiles of 15mm fir wood. Traditionaly , those houses were made of local oak, but, I choose fir wood because of it's weight.
Finish wood varnish/stain oak colour tone.
