Square cross-section brown wooden logs with cut-outs to allow corner crossing. These sets vary from other log cabin types by the inclusion of 'caulking fillers' betweem the log layers. These are narrow, thin strips of wood with a ridge on each flat face which fit into grooves on the upper and lower faces of the logs. The sets include green longitudinal roof slats which are carried on gables formed of progressively shorter logs. Windows and door are printed card. There is a red chimney.
