balcony safety netting

We have a new owner soon to take possession who has advised our SM to tell ‘strata’ that they are installing safety netting around their balcony to keep their active 2yr old child safe.

At least they were told by the SM that they would need permission to do this.

I understand that they now have legal advice on this – the details they provided were photos of other balconies with this netting installed and also that the netting met standards in South America.

Does anyone have any experience with this type of renovation.  Of course they will be adding to common property etc and will need an SBL to do this.  Personally, I would not like the OC to approve this as it won’t meet ‘appearance of building’ by-law and if the OC approved and the child or someone else fell through the netting then the OC would be held responsible.  Would they also need council approval?

Also we have been told that they are going to change ‘a few rooms like the kitchen around’.  I see big dangers in this too eg, if they decide to swap the kitchen with the dining area then any noise transmitted through the floor could not be dealt with as it is an ‘exempt’ area.

Thoughts please.
