Hello Molder,

Thank you for the feedback.
I must confess that I am still not at all sure whether the floor was raised or the walls were lowered.
However, I am relieved that it is now established there are indeed two heights to the KC - I was beginning to feel that I was ‘losing the plot’ more than I usually do.

Does it matter whether the floor was raised or the walls were lowered?
Suffice to say I believe it does, and if I read him correctly it matters to Jacob, too, though for reasons different to mine.

I’ve not heard of this type of room before; I look forward to seeing the photo.

According to Cole’s 1925 survey, the mean sides are: North 230.253m; South 230.454m; East 230.391m; West 230.357m – errors 6mms to 30mms (?).

Sorry, I don’t understand what you are saying here.
AFAIK, there is no ‘ancient metres 3.3 feet’.
