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 England under the Affordable Homes Programme
  • assess the potential land value where a local authority is considering a disposal
  • bid for the development of public land under the agency’s Delivery Partner Dynamic Purchasing System

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.
