Details

The development appraisal tool is intended for use on small and medium to medium/large size schemes with a development period of up to 15 years.

The tool can be used to:

  • analyse whether the level of required planning obligations is viable
  • help local authorities consider the balance between affordable housing and other planning obligations
  • assess the case for financial support from the Homes and Communities Agency under the Affordable Homes Programme
  • assess the potential land value where a local authority is considering a disposal
  • bid for development of public land under the agency’s Development Partner Panel 2 process

A bid comparator is available to help compare a number of submissions and their assumptions.

Version 4.02 of the model has 5 phases for all tenures and infrastructure, to enable modeling of longer term schemes.

Excel 2003 users with all service packs installed can open the Excel 2010 version 4 file and ‘Save as’ an Excel 97-2003 .xls file.
