Dog Leg Stair. A compact form of half turn stair landing where the landing is the width of the two flights of stairs, plus a small amount, say 150mm to make sure that the where the handrails and structures pass there is clearance for the hand grip.
Note! External stairs like the one above have the bottom landing structure at a height that is easy to walk into. Hence the pipe handrail to stop the public from accidentally walking into it.
In the sketch above I show a couple of slightly different quarter turn landings, but also note my remark that it is always best practise in any one stairway to keep the landings the same size.
Note the modern practise in public buildings of highlighting the first and last treads of a flight. In this case with non-slip nosings.
