Self Contain. What Is It?

Can someone explain what is "self contain" to me. Do you have a layout/plan by any chance. Same as mini-flat?

A self contain is kind of 1 room apartment where you have your kitchen separate,toilet and baths are together in a separate compound.It is the samething as miniflat but just it use to be single room and in some cases it is 2 room self contain.The advantages is that is you don't shear anything with anybody but still one room.While the advantages is that there is no exit door to the backyard or to the kitchen.
