The council will permit the re-use of buildings within the Green Belt or Metropolitan Open Land provided that the following criteria are met:

1. The proposed use does not have a materially greater impact than the existing use on the openness of the Green Belt or Metropolitan Open Land, and does not conflict with the purposes of including land in it;
2. The buildings are of permanent and substantial construction, and are capable of conversion without major or complete reconstruction; and
3. The form, bulk and general design of the buildings are in keeping with the locality. Where necessary the council will exercise strict controls over development for re-use.
