Perhaps after the war, when the land was being returned to agriculture, and when the villages were being rebuilt, a concurrent development of the mechanised side of farming meant that fewer labourers were needed than before the war, and so the rebuilt villages reflected this. The Somme villages in the part of the Somme area I have described so far are all pretty, and typically Northern French, but very small. Beaumont Hamel has a church and maybe 20 houses. Auchonvillers, just inside the British lines, is not much bigger, although it, too has its church. Neither village has a shop, neither has a bar.
Houses are usually small - two floors.
Sometimes you may find a slightly larger one here and there, maybe at the end of the village. The farms look at first like long high barns, running right along the side of the road. There is always a large, wide, usually arched gateway in the centre and when passing and looking inside, one sees that the farm is a fully-enclosed rectangle. Stables, cowsheds, etc, form two sides of the rectangle and the fourth side, opposite the gate, is taken up by the house itself, usually considerably grander than the more easily visible village houses. They are just like the farmhouses described in the memoirs and diaries of many, many British soldiers.
