Brian Gaff formulated on Friday :
There are some in Redhil where the small box room upstairs has a wall that
has an angled bit near the floor over the stairwell to allow taller people to
climb the stairs without knocking themselves out. For the want of a few more
inches in depth, this would not be required.

My semi has the small bedroom over the stair. It has a cupboard space
in that bedroom above the stair, the base of which is a few feet up
from the bedroom floor. That to allow for extra stair headroom.
