Yurt living on land with planning permission for house

[naturelover]

Hi,
Im hoping to buy some land in a rural location within County Durham (hopefully in a remote region) which already has existing planning permission to build a house.
My question is... instead of building a house on the land, would i be able to live in a yurt permanently instead of building a house on the same spot which already has planning permission for a house? Or would i need to apply for permission for yurt ? thank you
