The general rule now being operated in Wales is that two contiguous properties in the same occupation are only assessed as one if they can be considered a self-contained unit of property.
Y rheol gyffredinol sy'n cael ei gweithredu yng Nghymru bellach yw na ellir asesu dau eiddo cyffiniol o dan yr un feddiannaeth fel un ond os gellir eu hystyried yn ddarn o eiddo hunangynhwysol.
