$2500 for strata renovation approval?
Hi all
I own a middle-floor unit in an apartment in NSW. I've been entertaining the idea of having a Zen garden on my balcony, and after some research I've figured it would require a 5cm bed of gravel with appropriate drainage layers underneath (geotextile mat + drainage cells) to prevent damage to the tile/waterproof membrane beneath. All of this would sit on the tiled floor without any drilling, nailing or adhesives. The total cost of materials would be $620.
Regarding weight: I did the maths and the total weight of the garden would be 77kg/m^2 evenly distributed. I googled around and the AS1170 standard says balconies are rated for 2kPa or 200kg/m^(2), which leaves about 120kg/m^2 spare.
I've emailed my strata manager to see if any owners corporation approval is required, and they said it would require a special by-law + to obtain approval, the cost would be $2500.
This seems like a lot, especially considering it would cost 4x as much as the cost of the project itself. Is this a normal cost for obtaining approval? Would I need a special by-law in the first place for what I'm doing?
