I disagree with the idea (posted in this thread) that huts will become unrepairable after a time. A neolithic hut can easily be repaired, indefinitely (Iāve literally made such a hut and repaired it). There are other reasons for abandoning a settlement or turning a hut into a midden, but these are not based on repair issues.
Neolithic houses were quite sophisticated structures for their time. Far from the caves which many, unfortunately, and incorrectly, associate with ancient peoples, Neolithic houses often had wooden walls, thatched roofs, and even stables for livestock in the latter half of the period. Though basic in construction, Neolithic houses could be found on stilts near the waters or even buried partially into the ground or the sides of hills to aid in climate control. Some Neolithic houses were long and rectangular, such as the LBK Longhouse, and some were circular. The layout of Neolithic houses was especially important given the harsh environments some peoples lived in.

The houses of an LBK village were sturdy wooden structures designed for the harsh winters of Europe and the occasional floods from the rivers that people so often lived near, as they still do today. The sides of the houses were caked with mud to keep out rodents and insects, and the dirt floors were covered with dried mud and old worn animal hides. The roofs could be propped open in the warmer summers to let heat out, and covered with extra mud and thatching during the cold winters.
The construction becomes even more sophisticated as we look at Anatolian or Levant dwellings. Walls are made from Mudbrick and plastered while roofs are made from wooden timbers. Rooms contain storage areas, rush mats upon plastered floors. Small ovens for bread and cooking areas are made from sturdy mudbrick and beds are made from platforms elevated via mudbrick. So strong where these dewellings that some even exist, to this day (e.g. Catalhoyuk).
