A development appraisal is a valuation which assesses a property with or without planning permission to establish the likely value of a future use or the value as a cleared site for redevelopment. The valuation is called a ‘development appraisal’ because the Valuer has to assess a multitude of factors including build costs.

Firstly, the Valuer has to assess the value of the completed development.For residential developments this is the likely end sales price of the units or accommodation to be created. For Commercial developments this will typically be the NET income of the completed development capitalised at an appropriate all risks yield. This is known as the ‘gross development value’ the maximum end value proceeds from selling or leasing the development.

Then from the ‘gross development value’ the Valuer then deducts land acquisition costs, building costs, profit, costs of finance and an appropriate profit margin for the developer to derive what the land is worth today. The valuer who will be a Chartered Valuation Surveyor will then make an end adjustment to the derived valuation is planning permission has not yet been granted.

In simple terms the valuation method is
Likely value of the future use ‘gross development value’
LESS costs
= what the land is worth today
(adjusted for risk depending on if planning permission has been granted or not)

How hope value impacts on development appraisals?

The good news is that the RICS* International Valuation Standards which defines market value as “the estimated amount for which a property should exchange on the date of valuation between a willing buyer and a willing seller in an arm’s-length transaction after proper marketing wherein the parties had each acted knowledgeably, prudently, and without compulsion” Also states that ‘market value’ includes ‘hope value’ and that means the ‘hope’ or likelihood of obtaining a future planning consent.

Any prospective developer will know that the certainty of a planning permission not only sets what can be built but also usually enhances the value of the land. In the industry this is called ‘planning gain’.

Ringley’s Chartered Valuation Surveyors not only have to keep up to date with building costs and construction methods but also Section 106 requirements for education, green space, infrastructure as well as in London the Mayor’s levy.

How is a site valued?

Issues that the Valuer has to weigh up include:

  • street frontage and return frontage (can be taken into account to enhance the permitted planning density)
  • current land use
  • land use earmarked in UDP
  • build density of nearby buildngs
  • planning prescedents in the area
  • policy on car parking
  • policy on mix of units
  • policy on lifetime homes, access and design
  • likely land contamination and remediation costs
  • ground condition and foundation issues

Then the Valuer has to weigh up factors to help him/her quantify what ‘new build premium’ should be applied. Factors that may be relevant will include:

  • proximity to open space
  • proximity to transport infrastructure
  • parking provision on site (included, spaces to be sold/rationed)
  • balconies, terraces, outside space
  • aspect (south facing?)
  • landscaping schemes
  • specification, number of bath/shower rooms, audio wired
  • room ratios, how accommodation out-performs older properties
  • for apartments, lease length
  • comparable new build sales
  • local 2nd hand stock sales

In weighing up costs the Valuer has to take into account:

  • market building rates
  • construction costs (including builders profit)
  • bank interest on the land
  • development costs and profit
