its massively overpriced through that type of service and they sell tiny areas but bigger ones can be ok, if you have no public row going through or neighbours then you can put a "mobile" structure on it there should be a rule against using hectares or acres , 100 x 100 meter patch of land is roughly 2.5 acres or exactly 1 hectare somehow people get messed up thinking about squared areas and think 10 acres is huge. when its a 200 by 200 meter square
