Within the overall objectives of the five projects, the first project is expected to explore the different definitions of density and the different methods for measuring density. It is asked to consider which approach or approaches best provide an understanding of two key issues related to higher density development: urban form and number of people in an area. In addition the project is asked develop a definition for different categories of density which can be applied irrespective of the site context to help provide clarity to a significantly wide ranging debate. The findings from the report are expected to provide recommendations on how a new Mayor could take account of these in the full review of the London Plan. The project will also provide a recommended approach for estimating density for understanding housing capacity at a strategic level.
