I count 9(?) chimneys, would this mean that there are 9 rooms inside of No. 26? And, with the chimneys being along that far wall in the photo, does that indicate all of the rooms were situated along that far wall too? (Wondering if I have to rethink the placement of the staircase)
The Goad map shows that the chimneys from no.26 are in a wall shared with no.25, so as Dave says one or more of the chimney pots could be from there. No.25 is shown as a stable with dwelling above.
