“(d) on the assumption that the price be diminished by the extent to which the value of the house and premises has been increased by any improvement carried out by the tenant or his predecessors in title at their own expense”
“(a) As a first step I have to eliminate the additional areas of the 2000 house brought about by the improvements carried out in the 1990s by the present lessees, such as the swimming pool complex, the garages and covered way as well as the GIA of the new living areas added to those of the 1927 house. For simplicity, I do this in two stages so that the additions made in (a) to (d) above are first eliminated. The GIA of the living areas is initially reduced back down to the GIA of the 6,000 sq ft at 102. This, together with the elimination of the swimming pool complex, garages and covered way amount to (£1,254,176 ) [as shown above]. (b) As a second step I reduce the area from the 6,000 sq ft of 102 to the 3,834 sq ft of the 1927 house at 102: 6,000 – 3,834 = 2,166 sq ft @£662.50 (£1,434,975 ) The value of the 2000 house, reduced to its 1927 size, but in its improved condition therefore becomes£5,429,176 -£2,689,151 =£2,740,025 ”
“I agree with the passage from Hague, “Leasehold Enfranchisement” (Second Edition) at para 9-47: “The manner in which the assumption is given effect is for the property to be valued (at all stages of the valuation) as if the improvements had not been made, i.e. as if the property had been in the same condition as when originally let, and it is their value, and not their costs, which fall to be disregarded”.”
