Exactly. And where were those who are now missing?
Those are just jpgs. The OP probably meant that I should dig out the files again and try to squeeze a straight staircase in here, 2 parking spaces and a shed. But I don't see any chance for that. Especially not for the straight staircase, and 2 parking spaces + shed only like this:

Or else back to the starting point and 2 cars one behind the other without a shed. But then where to put the bicycles? The OP has to make sure that he wants to live comfortably here and for that, it must work first and foremost. If the 2 parking spaces are really needed, the space should be planned consistently.
