Hi, I have always kept piggies outdoors in various set ups.
In the summer months, April -Oct, they do fine in a hutch with lots of hay at night.
In the winter months they would go into a shed with natural light (windows) and lighting ( so I can see). Also they have a tube heater in their hutch (which requires the shed to have electricity) and on very cold nights a heat pad, more hay and a blanket over part of the hutch.
I know some people keep them outside without any of this but if you can put them in a shed at winter it will also help you be in the dry when you need to clean them.
Good luck with the house move.
