Thank you for the suggestion. We had images with the original porch but unfortunately time and budget don't allow us to have them recreated. I'm glad you agree that a string colour is needed as my builder is keen to put on s modern oak door which I feel will get lost with the white, brick and clay tile colours. Railings is currently my favourite although I'm using it in my kitchen and have a grey bathroom too, Si wondering about deviating, maybe card room green or castle grey (which is more green than grey) - both F&B.

Jonathan originally said taller crittall would look better than the shorter ones even if we had less of them Posted a pic again of the whole room layout for you @Emily. It will have a dark blue black shaker kitchen with suspended chimney extractor on cables and wood effect floor. I’ve seen industrial style kitchens with both crittall and wider bifolds and they both look nice. I would go with bifolds for the cost now because we have a max budget to spent on the house to ever get our money back (it’s not that we can’t afford to do what we want as such but you don’t want to throw money away!) even though I love the Crittall BUT it’s the practical side that we can’t agree on now

I think this is a really common question for a lot of people. If you only need partial opening (so no bifolds) then sliding doors is the most practical solution, for all the reasons you've given - no doors flapping about, doors don't take up space internally or externally and you can leave it a little open or a lot open, plus maximum glass for light and views. As much as I love proper original Crittal, my husband totally thinks they look like glass garage doors - and that image ruined them for me! Still love them in other people's houses (when done well), but together with all the practical reasons, we won't have them in ours.

That door featured in the above image is an LPD Door. They are a main UK distribtor and Wayfair just buy from them. We as a company supplied one only last week for a customer. You could look at full glass or half glass. Look at LPD Door website and also J B Kind for ideas. None of them will supply you direct as they only deal with trade but both of their doors are available online through other suppliers. By looking online you will be able to get the name of the door. They also offer a critall look alike door but there was a very long waiting time for this. Just be aware that such a lot of doors are out of stock and if you buy from another company as opposed to the main ones they will not display the amount in stock so be cautious about parting with your money until you know it is a stock item.
