Prakash, land for smallholdings isn't cheap that's the first problem!
You can still buy land cheap, but without a house on it. then you have a real problem getting planning permission to build anything other than a barn!
Brian and I bought this place for £85,000 8 years ago, but it had an agricultural tie on it. we asked the estate agent about that and he said well as Brian already rears poultry, you comply with the tie. Okay, so we bought the place, but when we wanted permission for a poultry house, the council said that we didn't comply with the tie as we came from out of the area! Although we already raised poultry in Essex, the tie on this place meant that we should have lived in the 'locality' !!
So we tried to get the tie lifted. First time didn't work, but after 2 years and £6,000 we actually got it lifted, which means we can now sell to anyone who has the money!
But now, prices have shot up so much, that we can't realisitcally afford to buy anywhere around here for the sort of money we'd sell this place for.
but if your place is worth a bit, choose the sort of locations you are interested in, and contact any local land agents, companies like Rural Scene, & Brown & Co sell farms etc.
There are loads of places in Wales, but even there they are no longer cheap!
One of the problems was that retiring farmers liked their houses, but as they got older could no longer work the land, so a lot of land was sold off, leaving just half an acre with the house. Then when the farmer dies, the house is sold, but of course, no land with it.
My Brian keeps on about places with 20+ acres, but he is 64 next month and I'm 60, so I know we don't have the money or energy to do it. He of course, thinks he's invincible!!
I think I'd be happy now with enough garden to grow my veg, keep half a dozen chickens and a workshop where I can lock Brian in now and again!!!
