Environment Policy 1
Protects countryside from development that adversely affects it unless overriding need exists. Officer found proposal would not harm countryside as works are to rear, screened, and appropriate to converted barn in High Landscape Value area.
Environment Policy 2
Prioritises landscape character protection in Areas of High Landscape or Coastal Value. Assessed rear extensions as not harming landscape quality due to screening from public viewpoints and compatibility with site.
Housing Policy 11
Permits modest subordinate extensions to converted rural buildings if not adversely affecting character. Officer interpreted 'will not usually be permitted' as allowing further extensions if character retained; proposal complies as original barn interest remains apparent despite prior changes.
Housing Policy 15
Extensions to countryside properties must respect proportion, form, appearance; over 50% floorspace exceptional. 46% increase approved as design appropriate, below threshold, with delineation of new elements.
