@Silly_Savage erm didn't really notice anything temperature wise to be honest. But now I think about it, that is a good point. Doors back would be one option or a full opening up like the neighbouring House. The dodgy door with the pipe would probably stay if the former, and the window which is there repairing.
Estate agent hasn't send through the surveys so my offer isn't as high as it would have been. On the internal kitchen wall that needs a building control cert - the agent said 'it will have an RSJ otherwise it would have fallen down'. Without that paperwork, my offer will be retracted in short order
