Time for planning

Well I'm starting to research the idea of a static caravan on site or in a field, the realism that even the most humble of houses will push my income to its limits and will not allow me the land I need to become more self sufficient.
The caravan idea comes from when I lived in a caravan in my own  garden after my separation, it was peaceful  and gave me a sense of freedom, yes it was cold in midwinter in fact -3 inside , but wrapped in a good duvet I felt none of it.
Waking to bird song or rain was beautiful, and falling asleep to the sound of owls and wind was calming, so moving to a much larger space but still a caravan is appealing ; the issue will always be the land. More research is needed ! .
