Land was to be acquired for the development of a new town. The court faced the issue, in the context of a valuation for compulsory purchase, of whether the required disregard of any increase in value attributable to the ‘scheme’ meant that the valuer should disregard the scheme altogether or permitted him to have regard to it when identifying the ‘proposals of the acquiring authority’ in accordance with which the valuer had to assume planning permission would be granted. A valuer assessing land for compulsory purchase was at risk of having to ‘conjure up a land of make-believe’ and ‘let his imagination take flight to the clouds’ ‘What is to be assumed about the Walton Manor Estate itself? Here again one thing is clear. You are not to assume that it would have been developed in accordance with the proposals of the development corporation. You are to disregard any increase by reason of the estate itself being developed in accordance with their proposals. . . But you are to assume that after 10 years planning permission would be available for development as a residential area.’
and ‘It comes to this. In valuing the estate, you are to disregard the effect of the scheme, but you are to assume the availability of planning permission. This is best explained by taking an imaginary instance: A scheme is proposed for building a motorway across Dartmoor with a service station every five miles. Suppose that land is taken on which a service station is to be built as soon as possible. In assessing compensation, you are to disregard any increase due to the proposed motorway, or service stations. But if the landowner had already been granted actual permission for that piece of land for commercial purposes (for example, as a cafe), you are to have regard to it: see section 14 (2). Even if he had no such permission already, you are to assume that he would have been granted planning permission for a service station; see section 15 (1). And you are to value that land with that permission in the setting in which it would have been if there had been no scheme. If it would have been a good site for a service station, there would be a great increase in value. If it would have been in an inaccessible spot on the wild moor, there would be little, if any, increase in value because there would be no demand for it. A further complication arises when the proposals are not put into effect for 10 years. Planning permissions are not in practice granted so far ahead. They are only granted for immediate development. In the illustration you are therefore to assume that, after 10 years, planning permission would be granted for development of a service station – in a setting where there had been no scheme.’
