Having discussed this matter with Turkish friends in the past, their advise is to put the first, and dirtiest, wipe down the toilet and the rest into the bin. This lessens the chance of a blockage and reduces the smell in the bin.
Furthermore, although you may have wide-bore pipes in a new build, if you're not connected to mains sewerage but have a cess-pit, you want to put as little paper into it as possible and so reduce the amount of times it needs emptying.
