Awning Encroachment

Dear Jimmy & Strata Gang,

an external electric awning was mounted  by ground floor owner above the upper unit’s floor line breaching the double brick cavity causing the upper unit’s skirting boards to pull away from the wall and the wall to crack. Plus, the awning was mounted in front of the gas pipe. The gas pipe entry to the upper unit flooring is well below the awning cassette. 

Not only is the internal skirting boards disturbed and the wall cracking I am concerned the power points in the skirting may be vulnerable/damaged.

i am astounded the awning is mounted so high on the external wall around the gas pipe clearly above the gas entry to our unit & the internal damage caused. 

What do I do? Is this kosher?

I appreciate your feedback to this matter. 

Aaaahhhhh. Pre holiday worries!
