Quite simply, a matwell is a hole (or recess, to be more technical!) in your flooring around your external door, in which matting is fitted as an integral door mat. Ideally, the matting should be flush with the surrounding flooring to create an even, continuous surface. You can create a size of doormat (and matwell) to suit your space. We would recommend going a big as possible to allow visitors to take a few good steps onto the mat. You may want to source a matwell frame or flooring trims to help finish off your matwell, but this is not essential. Sometimes it is worthwhile seeing what the mat itself looks like in situ before making this decision.
