MR JANUARY
The entire area of that front room from about the 
staircase to the double doors, the dimensions of that room is about 5 
metres in width to about 10 metres in length.  I was sitting right at 
the back of the raised platform where there is a pillar indicated in 
line with the staircase, that is above the point "d" that is indicated 
on the sketch, there is a pillar above that point, and I was sitting 
close to that pillar.  So that would have put me about eight, nine, 
maybe ten metres away from the double doors.
