There is one Type P2B; it is a penthouse flat in John Trundle Court; and it fits in with the 15 Type P2A whose layout is almost identical. The only difference is that it is the mirror image of the Type P2A in layout. The entrance is off an adjoining central spiral stairwell and lift unit. The kitchen is at the back, and the main room - 'the bed sitting room' - is at the window end, looking out of one or other side of the building. Also at the back is a spiral staircase to the upper floor which contains the bathroom and a bedroom.
I don't have the actual plan.
