“Mr Yasin acknowledges in his report that a lease extension of this property would include compensation to the freeholder for development value. It is his opinion the uplift value arising from the two bedroom extension is around£60,000 . He includes a sum of 1/3 or£20,000 of the uplift value as compensation. Under the prescribed valuation method this sum is assessed at the valuation date and is payable as part of the premium on grant of a new lease. The Expert in his premium calculation has deferred the payment of this sum to the reversionary date and this does not comply with statutory guidance. The tribunal includes the compensation sum for loss of development of£20,000 as a separate compensation head in their premium calculation.”
“It is the role of the Tribunal to act on behalf of the missing landlord and secure appropriate compensation for the parties in their absence. It is manifest the hypothetical flat has the development potential of the roof space conversion. The expert told Tribunal the development value amounts to£20,000 as at the valuation date. This value is not challenged by Tribunal. Any freeholder would seek this sum in compensation in return for the grant of consent to the works to the hypothetical property. This sum forms part of the premium payable for the grant of a new lease. The 1993 Act and the statutory prescribed valuation method do not specify or require the deferment of the development value portion of the premium.”
“2 The premium payable by the tenant in respect of the grant of the new lease shall be the aggregate of— (a) the diminution in value of the landlord’s interest in the tenant’s flat as determined in accordance with paragraph 3, (b) the landlord’s share of the marriage value as determined in accordance with paragraph 4, and (c) any amount of compensation payable to the landlord under paragraph 5.”
“5 (1) Where the landlord will suffer any loss or damage to which this paragraph applies, there shall be payable to him such amount as is reasonable to compensate him for that loss or damage. (2) This paragraph applies to— (a) any diminution in value of any interest of the landlord in any property other than the tenant’s flat which results from the grant to the tenant of the new lease; and (b) any other loss or damage which results therefrom to the extent that it is referable to the landlord’s ownership of any such interest. (3) Without prejudice to the generality of paragraph (b) of sub-paragraph (2), the kinds of loss falling within that paragraph include loss of development value in relation to the tenant’s flat to the extent that it is referable as mentioned in that paragraph. (4) In sub-paragraph (3) “development value”, in relation to the tenant’s flat, means any increase in the value of the landlord’s interest in the flat which is attributable to the possibility of demolishing, reconstructing, or carrying out substantial works of construction affecting, the flat (whether together with any other premises or otherwise).”
“...The [value of vacant possession at the end of the term] has been arrived at by ascertaining the open market value of the freehold interest with vacant possession as at the valuation date and then adjusting that value to reflect the fact that vacant possession will not be available until the end of the term. The adjusting factor is called the “deferment rate”
