on both sides of it. To the left and right of this room are small bedrooms. One of the distinctive features of the stall house is also a very steep and high four- or two-pitched roof, which is apparently caused by a large amount of precipitation in the Netherlands. Such shelters were also convenient because an ample attic space was formed under them, where hay and grain supplies were stored. The roofs were covered with thatch, later with tiles. The walls of ancient houses were made up of vertical pillars connected by wattle fences, in the Middle Ages and up to the 19th century, frame walls predominated everywhere.

**Frisian house (GULFHUIS)** is, typical in the southern regions of the Netherlands and almost everywhere in Belgium, was often called Franconian or even Celtic by romantic ethnographers. Archeological materials indicate that its origin was somewhat different from the two previous types. It differed in the internal layout, the kind of connection between residential and utility premises, and design. The house's core was formed from a single chamber building with a central hearth, from which very early with a transverse partition at one end stalls were fenced off. In the early Middle Ages, another living room was fenced off behind the hearth on the other side. Frisian house (GULFHUIS) is characterized by a transverse division of the entire room, which is why in the Netherlands it is also often called "DVARSHHOIS". A small front or vestibule is usually separated by a light partition near the entrance in the main living room. The fireplace is located at the left or right of the wall from the front door.
