I've almost completed my small build bungalow - one of the neighbours complained about an upstairs opaque window that wasn't on the original plan submitted to planning.
I had already mentioned this to the architect before the plans were finalised and was told - via email - it wasn't necessary to be that specific.
Next step now is to apply for a variation in order to get retrospective planning approved for the window at a cost of £235.
I asked if he will contribute towards the cost - as it was his inaccurate advice that caused the problem - and he's refused. I don't think there's any other option but to pay so that he can resubmit on my behalf.
