Most architectural remains visible today on the hill belong to the Middle Neolithic period (6th millennium BC), which is the peak time of the settlement.
During this period, the houses were built with durable materials such as stone and clay, and were square or rectangular, usually with one room. They had stone foundations and unbaked mud brick walls, which offered good living conditions as mud bricks are highly insulating. The roofs, made of timber and reeds, double-pitched or hipped depending on the size of the house, were covered externally with layers of clay stacker. On the roof there was a hole for the smoke coming from the fireplace. In the end, they plastered all over the house with a thin layer of clay, and they often painted the exterior walls.
The houses are built and rebuilt in the same position and they all have approximately the same orientation. Their size varies from 20 to 70 m². Narrow alleys between them formed squares in places, like the empty space between the four one-roomed houses (38-50-37-47) in this part of the village. Among these houses stands the so-called "House 50" which represents the largest house in the settlement of Sesklo during the Middle Neolithic period.
Both inside the houses and outside in the areas beside them, several structures served the everyday needs such as fireplaces, ovens, storage and work places. The fact that every house had its own storage and work places suggests that each family had some autonomy in serving the daily needs. Overall, there were found 22 full and 12 partial households.
A modern reconstruction of Neolithic houses you can visit in the park of Anavros, at the area in front of the Archaeological Museum of Volos.
