Changing which side of a window opens
Planning Permission drawing seems to show a two pane window in extension opening on the left (looks like there is a thicker line on this side). Is it now written in stone or can a right opening window be installed instead.
NB: There are no notes associated with the application that state which side opens
First check your decision notice for any conditions or informatives that may relate to this window. If there is nothing limiting glazing type or opening direction you can change the side by submitting what is called a non-material amendment - if you want to do it by the book. This will attract a fee but at least you are covered. Call the planning officer for advice as these are relatively new types of applications so some councils may be ok with giving direction over the phone.

I agree with UK Property Services, if it was specified within the planning app. how they would hang, this could be an issue. However this is a minor detail for planning purposes and not likely to attract interest. As previously mentioned, you could gain peace of mind by contacting your Local Authority to confirm. I have submitted many planning applications where the 'as built' has minor changes such as this, and it's never been an issue. If you wanted to move the location of the windows along the horizontal or vertical plane, that would be a very different matter.
Hope that helps.
