Wood as a shelter - in the past and now

Wood has been a part, whole or in part, of the buildings built by the man from the Neolithic; before the man is available with tools with sufficient capacity to court and to work wood (a tool with sufficient capacity to court need not be anything more complicated than a stone axe, for example) is very likely that you already use wood as a material for the construction of their first shelter. Nowadays, the tree is mostly used as a decorative element to give the aesthetic view of the building. This is exactly what I have tried to show in my video: How the role of the wood has changed over the years in building the living quarters. :)
The video is captured in the villages of Babintsi, Ribaritsa, Vasilyovo, near the town of Teteven, Bulgaria.
