House on the end

...of the village. I pass this house at least once a day and if anyone's about they always wave and shout hello. The sound of sheep baa-ing always comes from the ground floor, and there are various heaps of this or that dried vegetation stored in the garden under cover, presumably to feed the sheep. But, although there's a large flock of sheep grazing, usually at the other side of the village, I've never seen these particular sheep enter or leave the building.
