   Yes - planning permission is likely to be required and you should contact planning services on 443 2381 before starting any work.
   No - go to question 2.

   Yes - go to question 4.
   No - planning permission is required.
   
4. Will the building, including foundations and guttering be constructed entirely on your own land?
   
   Yes - go to question 5.

5. Will any part of the proposed building be higher than four metres if built with a pitched or hip roof or 3 metres if built with a flat roof?
   
   Yes - planning permission is required.
   No - Go to question 6.
   
6. Will the proposed building, together with any other extension to the house, garage or any other building erected since the house was built (or built at the same time as the house and which is to remain) cover more than half of the curtilage? (curtilage means the front/side/rear garden and driveway but does not include the area of ground covered by the house as first built.
   
   Yes - planning permission is required.
   No - go to question 7.

8. Will any part of the proposed building to be extended be within five metres of the house or be within five metres of another building (that exceeds 10 cubic metres) which is within five metres of the house?

   (b) any other detached buildings erected at the same time as the house or since the house was built, including garages/car ports, greenhouses, sheds and other buildings/structures which are 10 or more cubic metres and which are at present within five metres of the house or which would be within five metres of the proposed building.
   
   Cubic content is an external measurement calculated by multiplying length by width by height and must include all of the structure including the roof.
