Hope ValueOpen market value includes such an element of Hope Value (if any) as the property may have for other uses other than the existing use (i.e., alternative use) or for the realisation of any "marriage" value, which the property may have for merger with another property, or which an interest in the property may have for merger with another interest in the same property, but limited to the extent that the expectation of realising such hope value would, in practice, be reflected in offers made in the open market by prospective purchasers (other than the additional bid of a prospective purchaser with a special interest).Alternative Use Value, therefore, would be related to definitive information as to the statutory and/or other consents, or the prospects thereof (e.g., superior landlord's approval) regarding change of use or other matters. No unrealistic assumptions however, would be made.
