Bay window movement

On occasions we see a bay window which has moved in relation to the main building.

Recently we noticed evidence of historical structural movement to the front bay window structure of a property.  It is likely the front bay window structure had slightly tipped outwards in relation to the main building.  Our surveyor saw evidence of some cracking/filled mortar joints and brickwork externally and also evidence of some movement between the floorboard and bay window structure at first floor level.

Based on a one-off inspection, the level and nature of movement appeared to be minor and historic in nature.  It is not unusual for the foundation to the bay window structure to be constructed to a lesser extent than the main building structure.  There is often therefore some differential movement between the bay window structure and main building.  In this case the surveyor felt that the level and nature of movement to date did not warrant urgent remedial work.
