Will Getting Roof Rights Increase our Property Tax Amount?

Hi

So, we are pretty close to getting this completed with the roof rights. Attorney papers, architect papers. One question I do have is, will our property taxes be affected once we actually have roof rights? I spoke with somebody at the city register who handles the filing and he told me our property taxes will be recalculated because of the additional limited common element (roof) space.

Does anybody here have any experience with that and know possibly how much extra $ we will be looking at in taxes?

Thanks very much!
