The number of landowners in the countryside is increasing as more people join the rush to buy a place with space in the country.
A thirst for houses with land is unquenchable, despite a sharp rise in land prices, according to estate agents Savills. The firm believes a reduction in the amount of land coming to the market coupled with tax incentives may have led to the surge.
Richard Binning, who is based at Savills' Oxford office, said: "The thirst for houses with land seems unquenchable, from large farms, such as Elm Bank with 420 acres near Stow on the Wold, to smaller acreages, like Scotsgrove Farm at Thame with 70 acres.
"The market shows no sign of downturn, especially for farms and land with houses, even though the price of land has risen sharply this year - a factor that has often been masked by the value of the house."
Mr Binning said there was an inverse relationship between land price and the size of holding - especially when the land is next to a main dwelling. The value of the first two acres surrounding a house is not based on agricultural values, but on its impact on the overall value of the dwelling.
He said: "The owner of a £350,000 house in a good location could expect to pay up to £30,000 for a third of an acre immediately next to it, with the cost more than covered by the effect the land would have on the value of the house.
"If, in the same situation, an acre was for sale, its value would be nearer £45,000 than £90,000 per acre, with the next two to five acres less valuable again and so on.
"However, where the acreage available to a house is much greater, it will be nearer the open-market value for good quality arable land - around £3,000 per acre."
Mr Binning said there was an increasing demand from people wanting a land buffer around their homes. He said tax incentives in owning land for either inheritance tax relief or rollover relief was also fuelling the surge.
But, he warned that buyers may need to seek planning permission to turn agricultural land into gardens.
"Buyers must remember that farmland is agricultural in the eyes of the planners, and permission will be needed for a change of use whether it be to garden, equestrian or any other use," he added.
