Can any one help with general regulations on residential planning permission in Istanbul. If you wish to put an additional room on a roof terrace, would it be necessary to apply for planning permission to do so? In the UK there are areas where planning permission has to be sought and where (in conservation areas) it is very difficult to obtain. Does something like this exist in Istanbul? How would a person know if planning permission is required? Who would deal with the application? Many thanks
