10. Proposals for the change of use of redundant agricultural buildings considered to be worthy of retention must be accompanied by: 
(a) A detailed and accurate survey including full details of any structural timber framing.
(b) An accurate record of the building in the form of black and white photographs.
(c) Detailed plans indicating that the conversion can be achieved in accordance with the following obJectives:
(1) minimum alteration to the external appearance of the building;
(2) minimum alteration to the structure of the building;
(3) internal arrangements to respect the original character of the building.
(d) Details of the treatment of landscaping, open spaces and boundaries to respect the character of the building and its setting.

11. The City Council will, in granting planning permission for the conversion of redundant agricultural buildings to residential use, remove the "permitted development" rights conferred by the General Development Order.
The Kent Structure Plan makes a general presumption against development in the open countryside. An exception may be made to this presumption if a change of use is necessary to ensure the retention of a building which is of architectural, historic or landscape value.
To prove a building is redundant the applicant will be required to demonstrate to the satisfaction of the Council that the options for a continued or reinstated agricultural use have been fully explored and explain why the building is incapable of fulfilling any agricultural or other approved use.
The City Council wishes to ensure that any conversion will not prejudice the continued agricultural use of adjacent or associated buildings. Proposals for change of use will not, therefore, be considered in isolation but with due regard to the physical, functional and landscape setting of the building.
The most appropriate and satisfactory use of a redundant agricultural building is one similar to that for which the building was originally designed and which requires little or no physical alterations to the building. Conversion to residential use is very often the option which necessitates the greatest alteration to the physical structure and character of an agricultural building.
It is possible that a well planned and executed scheme for residential conversion may subsequently be altered by owners exercising their permitted development rights confirmed by the General Development Order. The Council will normally remove such permitted development rights by attaching a condition to this effect so as to bring those operations usually regarded as permitted development within the scope of planning control.
