MPP conducted excavations of roundhouses (somewhere in Scotland) and reported that there was a buried corpse beneath the doorway, in one of them. That's about as close as it gets.

It's quite easy to envisage a long barrow's appearance as a woolly thatched longhouse. And very literal too.

Burials within the settlement area and under houses is the norm for the period 7000-6500 BC in the SE Europe .

I was thinking along the lines of the possibility of a roofed long barrow being the original home of a leader/chieftain and his family and as they died off were laid to rest in the side chambers then when 'full' the whole thing becoming just a stone capped chambered tomb as we know it today.
