A variant spelling of blindstorey; an architectural level or story without windows or with decorative false windows.
American spelling variant of the British 'blindstorey,' using 'story' instead of 'storey,' from 'blind' plus 'story' (a building level).
The difference between 'blindstory' and 'blindstorey' is just American versus British spelling—but it reminds us that architectural terms traveled differently across the Atlantic.
