Further to your response to question 2019/8973, the second paragraph of your response states: “My draft London Plan explicitly recognises that the appropriate density of a site is an output of a process of assessment, rather than an input.”

Policy D6 at D States:

The following measurements of density should be provided for all planning applications that include new residential units:

1) number of units per hectare

2) number of habitable rooms per hectare

3) number or bedrooms per hectare

4) number of bedspaces per hectare.

Policy D6 does not define the process by which to analyse these parameters to define an acceptable Housing or Residential Density.

If the assessment of a proposal to define the appropriate density of a development site is an output of a process, how exactly should those input parameters, listed above at 1 through 4 of that process, be analysed and by what methodology to provide an output figure to define the appropriate density and what are the individual weighting factors?

Density measurements are an output of a proposed development design not an input parameter to dictate the feasible number of units. The value of these density measurements is that together they provide a more meaningful numeric comparison between different developments, and between a proposed development and the surrounding area, than is provided by a single density measurement. Requiring these measurements in the London Plan helps ensure this data is collected across London for all relevant developments and thus can be used to inform future reviews of the London Plan.

My officers in the London Plan team would be happy to meet with you to discuss the draft London Plan’s approach to density with you in more detail.
