This is Andrew, whose dad has built him a tardis and a Dalek at their home in the south-west of England.
His dad Will says it took a year to make the tardis, and takes four people to lift it.
It lights up inside and flashes blue, but it doesn't disappear like the real thing.
But his Dalek, which is easier to transport, sometimes goes to special events in the area.
