Bigger and better houses in the Bronze Age
As the people of Europe began to have more contact with West Asia and North Africa in the Bronze Age, about 3000 BC, they started to build more complicated houses like their neighbors and trading partners.
Urnfield culture villages
As the Urnfield culture spread across Europe, people were richer, and there were more of them. They began to build wooden fences or stone walls (without mortar) around their villages, and many villages were on top of hills. Some villages were built on stilts in the middle of lakes for safety (compare these to earlier Chinese stilt houses).
Most houses were still pretty small, but some were bigger, and might have been houses for a chief and his followers, dependents, and servants or slaves.
