Abstract
Over the past 50 years, we have got used to looking at LBK longhouse interiors through the eyes of P.J.R. Modderman and later A. Coudart. However, the internal divisions and interpretations, which they suggest, are difficult to apply to the eastern LBK. An analysis of houses from Lesser Poland illustrates that a different structural design was used in this region, but the division of longhouse interiors adhered to the same concept as that noted throughout the LBK. The new interpretation is based on three fundamental tenets. Firstly, not all posts used in the construction of LBK longhouses served a structural purpose. Secondly, not all major divisions of longhouse interiors are immediately visible in the archaeological record because not all of them required the use of solid structures in the form of earth-fast posts. Thirdly, it cannot be ruled out that LBK longhouses may have had a habitable, full-length upper storey.
