Balcony height out of date.

We own a unit, built in the ’70’s,  which has balcony railings below the current approved standard height. For safety reasons we are wanting to add toughened glass panels behind the existing railings so that the balcony railing will be at the current approved standard height.

New regulations require that a metal strip be added along the top of the glass panels. We have designed the distance of the strip along to top to mirror the spaces between each horizontal railing already existing.

We need approval from the Body Corporate. We have been told that the residents don’t want the ‘look’ of the building to change and that our new glass panels and metal strip will do just that.

We are on the 5th floor of an 8 floor building. The top Unit replaced the railings entirely with framed glass panels some years ago. It is the only Unit in the block to have made any changes to the balcony increasing the railing height. That Unit has changed hands twice since.

Is it absolutely necessary,i.e.mandatory, to have the metal strip along the top of the finished height of the toughened panels?

Can the Body Corporate deny our request to increase the height of the balcony railings for safety reasons as described?
