These plans represent, in diagrammatic form, the dimensions of the barn that we find today.
Over the centuries minor modifications have taken place.
No attempt has been made to determine the original floor level.
Whilst the overall measurements of the interior walls are accurate (33' by 148' 6"), the positioning
of the arcade posts have been standardised for illustration purposes.
The average distance between the arcade post centres is 16' 6", their actual locations are +/- 2".
Measurements were taken using a laser range instrument.
