Executive Committee Issues Extending Pergola In A Townhouse.

I am wishing to extend my pergola however i have been met with a significant amount of obstacles which i hope someone can render some feedback on.

A proposal of the job was sent to the executive committee which was subsequently rejected without any reason whatsoever.

And an offer to submit diagrams and photos of the proposed work has been ignored. Having a secretary who is a pain in the ass does not help things either. I have approached the strata management unit for advice but they told me its out of there hands.

The only member of the executive committee who approved our job stated there is some sort of rule which indicates the length of the pergola cannot exceed 3m long from the house. Is this correct? She could not find information to back up this up so hopefully someone can assist and confirm this measurement please?

Lastly is anyone able to offer advice whether i am able to just go ahead and extended the pergola?

Thanks
