The plans for our Cremorne mention that the toilets are, but there's no mention of the other exhausts.
And if this isn't standard, has anyone ever considered upgrading? What was the cost? Thanks!
EBH follows what in the BASIX. I asked for the basix document where it mentioned one of the bathroom toilet needs to be ducted externally. HSI electrical was charging me for ducting upgrade but after showing the BASIX requirement the adjust the pricing. I suggest ask your CSA for detail Basix report.
