DMH 8 Implementation of affordable housing

To ensure that Core Strategy Policy IS5 is applied consistently on all proposed housing developments, the requirement for affordable housing will apply to:

  • sites that are artificially sub-divided or partially developed (including but not limited to partial development of sites identified in the SSAD);
  • phased developments where a housing development is part of a larger development of 10+ units (gross);
  • additional units created through amended planning applications or subsequent applications on sites with existing planning permission, whereby the amount of affordable required will be calculated based on the total number of units that will be on the site;
  • proposals which fall below the 10 unit threshold:
    • Where densities fall below the minimum threshold in the London Plan Sustainable Residential Quality (SRQ) density matrix (London Plan Table 3.2) and/or
    • Where dwelling sizes significantly exceed the space standards in Table 3.3 of the London Plan
  • Calculations will be based on what the site could potentially provide having regard to Policy DMH4aiii, sites identified in the SSAD and in the Housing Trajectory; and the housing mix requirements in Policy DMH3.

In exceptional circumstances, a financial contribution may be required to provide affordable housing off-site where other sites may be more appropriate or beneficial in meeting the borough’s identified affordable housing needs. Alternatively the developer will be required to identify a site(s) which would be acceptable for the development of affordable housing. The affordable housing would be delivered at no financial advantage to the developer and prior to, or tied to, the completion of the on-site market housing. Further guidance is provided in the Council’s adopted Planning Obligations SPD.#

The Planning Obligations Supplementary Planning Document provides further detail on implementation of the affordable housing policy.

The Council will agree the site specific methodology to be used for affordable housing economic viability assessment with the developers, the Council’s independent consultants and where relevant the Greater London Authority.
