not really that interesting, the bugger who posted that, didn't mention that previously the floor was leased by a ocean research institute, hence the "swimming pool".. the institute didn't bother to revert back to normal flooring and UOL don't want to spend money on it hence when CPF took that floor, they have specifically informed their staffs that the pool is not available for usage and they was not charged for rent by UOL for that area cause it's out-of-bound..
