I want to make a REALLY large concrete worktop. Should I use the prefabrication method or “cast-in-place”?

With prefabrication, the larger you go the more difficult the concrete is to handle because you will need to flip it over once cured to process and seal it. You will need plenty of helping hands!

The “Cast-in-place” method does allow you go larger of course because it doesn’t need to be moved once cured and it also means you can have large seamless spans.
