I suspect that fairly advanced building techniques go back farther than we think. The thing is, the world is so large and the materials that would be used will prevent us from ever finding everything. Things like boats too.
The oldest known permanent, as opposed to temporary (structures used in pre-agricultural, nomadic existence), buildings are those which go back to about 10,000 BC, and they were very simple and low structures, with, from 9,000 BC onwards, evidence of rooftop paths for passing between "rooms"/units once they had the idea of constructing them against each other rather than separately.

But it is true that other buildings might have existed constructed with perishable materials, of a different nature.
I just tend to think that if the oldest permanent buildings that have been found are so rudimentary/basic/simple, it is unlikely that more sophisticated models existed before. However i would love to hear about any serious proof/evidence of more impressive buildings by/before 9,000 BC.
