From the Lower Rhine region to western Mecklenburg the Low German house was the dominant type of farmhouse. Further east it was found as far as the Danzig Bay, but manor houses ("Gutshaus") and farm workers houses were more common. In Schleswig-Holstein it was found mostly south of the Eider river, the old border with Denmark. In northern Sauerland and the Weser Uplands there was less of a sharp boundary and more of a gradual reduction in floor area as the terrain became hillier. In southern Lower Saxony the Hessian square farmstead ("Vierkanthof") is found well inside the Low German language area. In east Lower Saxony the "Niedersachsenhaus" and the square farmstead are interspersed like a mosaic. In Saxony-Anhalt there are none in the Magdeburg Börde and only a few in the Altmark.
