C13

Extensions to dwellings will be considered on their merits but the Borough Council will expect the following criteria to be satisfied:

  1. The existing dwelling must be an “original dwelling”* in permanent use as a dwelling.
  2. There will be an overall limit of one third of the gross floor area of the original dwelling (measured externally) prior to any later extension or alteration, unless the increased floorspace has no overall effect on the existing bulk and appearance of the dwelling.
  3. Those extensions which provide essential basic amenities such as a bathroom, toilet or kitchen, which are currently not available or are clearly inadequate, will normally be permitted.
  4. The extension shall not be in a form which would facilitate the future formation of a separate residential curtilage.
  5. The dwelling to be enlarged must have sufficient curtilage to accommodate the extension without undue visual intrusion into the open countryside.
  6. The appearance, massing, scale, form and materials of any extension shall be appropriate to the existing dwelling and the Green Belt setting.
  7. Proposals for domestic garages and for other outbuildings will be considered on their individual merits but will be required to be well designed, discreetly sited and subservient to the scale of the main dwelling on the plot.

* For definition of “original dwelling” see footnote to policy C12
