It is known how these cultures built houses. The houses were mostly 20 to 25 m long and 5 to 7 m wide, consisting of five rows of posts, the three inner ones bearing the roof's weight, and the two outer ones the wattle-and-daub walls’. These houses served to house people, supplies and animals, and they were always oriented in a certain direction (northwest-southeast or north-south). Within the settlements, irregular pits are encountered that, when houses were being built, were used as the houses’ excavations. They were then filled more and more with rubbish such as charcoal, animal bones, ashes, stones and potsherds. In a few built-up areas in the town's main centre, the streets have cut across several garbage pits. When opening up new cropfields, the farmers preferred loess.
