22 The valuations were determined on the basis of capitalisation of rent and discounted cash flow analysis. Mr Jackson reviewed the valuations and satisfied himself that the basis of valuation, rental and sales evidence relied upon and the analysis was in accordance with proper valuation practice and reflected the true market value at the relevant time. Although the valuations are for dates six months from the relevant base dates, Mr Jackson does not adjust for that period of time.
23 The next step in Mr Jackson's valuation is to deduct the lease/investment component to isolate the land and improvements component of value from the value of the lease to the Commonwealth Bank. This is said to reflect the value of the time and risk associated with placing a tenant. A period of 12 months is adopted with a discount rate of 8%. He then allows a further 5% for profit and risk.
24 Mr Jackson further deducts the added value of the existing heritage improvements by reference to a replacement cost assessment by a quantity surveyor engaged by the owner. The replacement cost is depreciated at the rate of 25% taking account of the age of the improvements, the fact that they must be maintained and continued in accordance with the Act, the recent refurbishments, the architectural and heritage significance and the significant costs of ongoing maintenance. Mr Jackson also allows for interest during the development period, savings on holding costs and loss of interest during the development period.
25 Mr Hill's fundamental criticism of this method is that it relies on the mistaken assumption that replacement cost does not equate to the added value of improvements. Mr Hill says that the investment value, derived from actual rental returns, already takes into account the heritage nature of the building, including its condition, shape and efficiency. Actual returns are lower than would be expected from a building with similar lettable area not subject to heritage constraints.
26 As I have said, Toohey's cannot be distinguished from the present case. Mr Jackson's approach to valuation is to subtract the value of the improvements from the improved value of the site, a method not available to me since Toohey's was adopted in Fenton. Even if Toohey's could be distinguished, and James v Valuer-General accepted, it would not permit me to value the land in the manner proposed by Mr Jackson. Mr Jackson subtracts a factor in addition to the value of the improvements, which he refers to as the investment value of the lease, from the improved value of the land. This is an additional element of the improved value of the property other than the intrinsic value of the land and the improvements. Consequently, I cannot rely on Mr Jackson's primary valuation approach.
27 As an alternative valuation approach, Mr Jackson conducts a hypothetical development exercise. For the purpose of this exercise, Mr Jackson assumes that the land is sold with a covenant on the title restricting development on the land to that which actually exists on the land. The fully leased, improved value, he says, is in the order of $125,000,000. The replacement cost of the improvements is $115,000,000. The hypothetical developer would incur additional costs such as interest, holding costs and selling and leasing cost. Ultimately, his valuation using the hypothetical development method results in a land value of nil or less. He supports this result by reference to the reasoning applied in Australian Postal Commission v Melbourne City Council [2005] VSCA 295.
28 This alternative valuation methodology was not considered by either party until the valuations experts conferred. Mr Hill does not undertake a valuation using this methodology. He sees the negative or nil land value deduced by Mr Jackson as evidence that the methodology is flawed in circumstances where over the three years in question the property generated an income of about $12,000,000. Mr Jackson's alternative valuation is not seriously considered, nor does it represent anything other than a "back of the envelope" calculation. The result is clearly not correct and would be rejected by any prudent hypothetical purchaser or vendor.
29 The Australian Postal Commission case involved Victorian legislation essentially similar to that under consideration in this case. The GPO building in the Melbourne CBD was determined in that case to have a land value of nil. However the Melbourne GPO had been subjected to a fire and the heritage improvements required substantial repair and refurbishment. That situation does not apply here. No work is required to restore the Commonwealth Bank building to the condition it was at the date of valuation.
30 Mr Hill's valuation proceeds on the assumption that on each of the base dates the primary use of the subject property was not materially different from typical modern office buildings in the Sydney CBD. He derives a s 6A land value (unaffected by heritage restrictions) of $1,900/m2 of net lettable area (NLA) based on comparable sales evidence.
31 Mr Jackson does not agree with Mr Hill's assumption that the subject is not materially different from modern office buildings in the Sydney CBD. He distinguishes the subject building on the basis of design, height, scale and nature.
32 It is obvious that the improvements on the subject land are different from typical modern office buildings in the Sydney CBD. However, for the purpose of determining the land value of the subject land unaffected by heritage restrictions, comparison with such developments is entirely appropriate. Section 6A requires the valuer to consider the highest and best use to which the land could be put at the base date and that is undoubtedly an office building. In Mr Hill's valuation, considerations under s 14G are considered as a separate step.
33 Mr Jackson is also critical of Mr Hill's selection and adjustment of comparable sales used to derive the $1,900/m2 of NLA land value. He identifies sales relied upon by Mr Hill as having occurred too far in the past to be of useful comparison. He says Mr Hill's 10% adjustment for development consent is "arbitrary" and "no more than a guess".
34 Mr Hill relies upon historical sales of development sites in the Sydney CBD for the reasons that there have been few such sales in the past decade and that there have not been significant movements in the market that would distort the site sale value. He considers that the hypothetical purchaser would take those sales into account. I accept these sales relied upon by Mr Hill as comparable for the purpose of the exercise he undertakes.
35 Mr Hill says that the usual approach to adjust for development consent is to defer the purchase price for 18 months at 10%. He adopts a simple increase of 10%, which he says results in a slightly more conservative adjustment. I accept this as a reasonable adjustment for the benefit of the development consent on the subject site.
36 A further criticism is that the calculation is on the basis of net lettable area (NLA). At the time of purchase, the NLA of a development site is not known, although the parties would be aware of the potential gross floor area. The error in adopting NLA is that it does not take into account the efficiency of the building, and this is particularly apposite in a heritage building.
37 The NLA is used by Mr Hill as it is the driving force in actual returns derived from a building. He says that a purchaser of a development site will consider the rental return from a project. The rental return is a product of the NLA and the rental return per m2 of NLA. The efficiency of the building is not taken into account when comparison is made on the basis of NLA. I accept this reasoning. The inefficiency of the subject building by comparison with modern office buildings is taken into account in the second part of Mr Hill's valuation where the restrictions of the heritage improvements are considered.
38 The second step in Mr Hill's valuation is to adjust the figure of $1,900/m2 of NLA to take into account the assumption that the only improvements that may be made to the subject land are those that are in fact present on the land, that is, the requirements of s 14G. He identifies areas of the subject building that would not attract the same commercial rentals as other parts of the building due to heritage restrictions. He applies a discount of 60% to those areas of the subject building that are basement/storage area and a 50% discount for level 9 (the Great Hall). This results in an average figure for NLA on the subject land of $1,749/m2. The applicant does not dispute the basis of this assumption. I consider this to be a logical deduction to take account of the greater area for which a lower rent can be achieved in the subject building than in modern office buildings.
