?Tennis courts are crucial,? says Rupert Bradstock of buying agent, Property Vision. ?Ninety per cent of our clients with a budget of £1million plus will want a country house with a tennis court. What people don?t realise is that if the property doesn?t already have one, it is not simply a case of installing one in the field next to the house. Planning permission will be required to put in a hard tennis court:

If it is in the garden, it is likely that planning consent will be forthcoming, but if it is in an orchard or field, then consent might be trickier to obtain. If a property does not have a tennis court and there is doubt over whether planning permission can be obtained, this would certainly affect saleability.?
