Roundwood framing is one of the oldest forms of timber construction, the timber is used 'in the round' that is to say in full circular lengths with little or no processing or slicing.

is what one might call a frame construction which is made using young growth round wood poles, here we call this round wood skeletal. Some of the earliest forms of basic shelter would have been made from natural found materials such as reeds, leaves, grass or bark laid over a simple frame of full branches that did not need cutting or slicing. Whilst early humans may have been nomadic, the frames could have been clad with animal skins and bound with natural reeds, often triangular and easy to erect and disassemble, commonly referred to as an early form of yurt.

The first recordings of a yurt were made by Herodotus of Halicarnassus who described yurt-like tents as the dwelling place of the Scythians, a horse riding-nomadic nation who lived in the northern Black Sea and Central Asian region from around 600 BC. Simple braced frames structures or reed hut shelters can still be found today in places like Sudan and Iraq, whilst yurts can be seen in Central Asia.

In places like the Cones of Cappadocia dwellings were constructed directly from soft volcanic stone without the use of timber. Other dwellings such as those found in Togo and Timbuktu were built with solid earth wall bases and thin wood and straw roofs. Hybrid structures using a timber skeleton as the primary base of the walls, plastered with wet earth and clay, might be seen in the Masai tribes in East Africa.

In Ethiopia, in the late 1800’s as timber stocks around Addis Ababa ran bare due to use as building material and fuel for a growing population, the king at the time planted Blue Eucalyptus due to its ability to grow quickly and ot regrow from stumps (early coppice wood). The Tukul or Sarbet grass house thus became a common round wood skeletal form of shelter, made with coppice round wood, wiht a triangular roof sitting on a circular structure of timber and reed that was then plastered in clay and earth. Many other examples of these simple timber round wood structures forming the basis of shelter, tents, and hybrid earth structures exist around the world. Examples can be found in the excellent pictorial essay book 'Shelter', first published in 1973 by shelter publications.
