ABSTRACT A log building construction in which each log is provided with a tongue on the upper surface and a rectilinear groove in the lower surface thereof. The edges of the tongue are beveled so that upon insertion into a rectilinear groove, elongated expansion chambers will be defined to halt the propagation of drafts between the mating surfaces of adjacent log courses. A check groove is provided at the bottom of each groove in the bottom of the log for the purpose of releasing tension in the log as it dries while the top surfaces of the log are completely free of grooves to pre- vent any accumulation of moisture or dirt which would lead to early decay.
