Hello Lee, welcome and congratulations on your land purchase. It's a great feeling
.
Are you near a village, as you would probably be better to rent a house in the village, as getting planning permission to build a dwelling on your land is a long and exhausting task apparently - years not months, with no promise of success at the end.
Meantime, think carefully about what you want to achieve on your land, and how much time and money you have to spend on it. Don't dive in straight away with lots of different species, start with a couple, perhaps some sheep or goats and definitely hens, which will need good security with you not living on site (I think thefts of crops and livestock might increase with this virus on the go and shops struggling with supplies). Gradually build up your livestock as you become familiar with the amount of work involved. Don't forget fruit trees, soft fruit and a large veg patch
We also have 9 acres - it seems massive when you first buy it, but it won't be long before you need more! We have always had sheep and laying hens, and have had pigs in the past. We now also have geese, but mainly we grow fruit and veg, and look after the environment on our patch. We have planted lots of hedges, a coppice, a copse, various wildlife areas, and we have filled our garden with flowers loved by bees, butterflies, hoverflies, night and day moths, birds and so on. We can no longer imagine living somewhere else.
