Extension Wall looks odd

[diynot57]

We're buying a house with a 2nd story extension above the garage.

The wall of the extension protrudes above the roof which is odd as other properties in the road have had a similar extension without the wall protruding above the roof line.

Does anyone have any idea why the wall has been made higher than the roof line?

Here is a link to see it on google maps: https://goo.gl/maps/XTFeQzRnxTtFq4uw7

if the roof was finished any differently it would hang over the neighbours.. not unusual.

Parrapet wall, Can cause issues if not sealed correctly , had frequent leaks caused by mine until it was removed.

I bet the architect was proud of that job

I,m guessing its a cock up in the fist place and that was a solution, I dough't think anyone would build like that on purpose.

Won't win any design awards but ,as others say, it will most likely have been built as a parapet wall to avoid the eaves and gutter overhanging the boundary.
