JUST FOUND WHAT COULD BE THE ANSWER...TEALEAF...the stag as you look from the front is the youngest part of the buiding,if you look from henry street at the lower roof that is the origanal building!how does he know you ask yourself! well i staggered into the loft with my torch and had a look at the beams holding the roof up, yes the ones at the front are old, but the attic in the lower part of the building are ancient.they are shaped like dogs back legs,its as if they cut a tree down and split it in half and used them to hold the roof up.......cant find my camera to take some pics but when i do i will show you its amazing what is holding that roof up, and for so many years.
