I think you'll have to go with white or whatever looks best indoors in those rooms. You can always think about getting the windows colour bonded at some point instead of replacing them. Then you can choose any colour for those inside and out! You can paint UPVC yourself - All of our windows inside are painted the same colour as the walls in those rooms so that the windows blend into the walls. They were dark brown / mahogany ( vile ) - Outside they are all sage green. If you're going to paint the frames inside which will brighten the rooms and let you have whatever colour shutters you like, use Zinsser 1-2-3 primer and then paint away.

Hi Fresh Kid, I'm a researcher with Openlight, a new startup looking to change the way homeowners buy and install windows in their home. We're at the very early stages of our business and looking to chat with people like you to learn more about your experiences and what can be improved. Would you be willing to have a conversation with us? Let me know and we can figure out the best way to get in touch. Thank you for your time and help!

I’m in Hertfordshire and I used Globe Home Improvement. They have offices in Beds and London. I’m not sure if they cover your area but worth a call? Have a look at their website and Facebook page. They are a family run business and Phil is so helpful. Great after-sales service too.

Our loft company came up with this design. Despite being aluminium, the frames take up a lot of the nice view. Cost £2250. Suggested making the central panel twice as wide and the two side windows smaller (narrower and less long). Does anyone have any bright ideas as to how to make this feature thin framed aluminium window more appealing?
