 The fact that distinct sleeping cubicles for individuals was not the custom suggests storage units of some sort.The settlement of the Middle Neolithic (5,000–4,000 BC), housed 500–1000 people in more substantial and presumably more family-private homes.Construction was the same, except the windows and doors were timbered, a fixed, raised hearth occupied the center of the main room, and pilasters and other raised features (cabinets, beds) occupied the perimeter.
