And would this mean that IF the lean-to was added later, then so was the arch extension that hovers over Mary's door? And IF these were added after the main house then what about the court cottages seeing as the left cottages are a continuation of the extra archway that is above the back window to 27's shop?
Those two windows (red/yellow arrowed) are curious indeed! Especially the one obscured by the lean-to roof.
