Joint housing land availability study

Powys County Council has to complete a housing land availability study each year to monitor the supply of housing land in its planning area (outside the Brecon Beacons National Park). We are required by Planning Policy Wales to ensure that sufficient land is available, or will become available, for a five-year supply of land for housing.

The study is undertaken with key stakeholders. The Studies provide part of the evidence base for local planning authorities’ development plans and for their review.

The purpose of the study is:

  • to provide an agreed statement of housing land availability for development planning and development management purposes; and
  • in situations where an insufficient supply is identified, to outline the measures a local planning authority is taking to address the shortfall.

The study also provides information on:

  • housing completions;
  • land availability on previously developed land; and
  • land availability on sites subject to flood risk.

Guidance on the preparation of the study is set out in Technical Advice Note 1, Joint Housing Land Availability Studies (TAN 1). Each study is prepared with a base date of 1st April every year to provide a comprehensive all-Wales picture of housing land availability. TAN 1 also provides guidance on the method for calculating housing land supply and the conditions which sites must satisfy to be included in the Studies.

Following a review of the process of preparing the studies, the Welsh Government put in place a revised process from April 2012.
