Wouldn't a joiner make them for you bespoke.

Solid oak tolerates temperature changes much better and better suits the front door. The front door is always exposed to moisture due to rain, snow, or fog. Also, the front door shouldn't fade over time due to direct sunlight falling on it in hot weather. I think it's much more profitable for you to take a solid oak door because it won't have to be changed after five years of use. We bought an oak door made of solid wood about ten years ago at https://www.ukoakdoors.co.uk/internal-oak-doors/four-panel-doors. I like that I don't see any cracks or wrinkles on this wooden door. My wife jokes that even my face is covered with wrinkles, despite the door has remained smooth and looks like a new one.

If you had a joiner out to quote you and tell him what you’re looking for he would be able to do it. Strangely enough it’s something hubby got asked to do only last week. Customer requested a solid section at the bottom and then glass at the top. Definitely doable.

Hi! A belated thank you to everyone who helped me finally make a decision! I went with a 3 pane sliding door (on a 3.7m opening) allowing me to open over half the width. I figured that with bifolds you would still have the frames stacked to one side which takes up a chunk of the opening as well. I chose the XP Glide from Express Bi-folds. Have found them professional and easy to deal with, we are just awaiting delivery now! The only bug I had is that their choice of handles were pretty basic, either a chunky (in my view an eye sore!) steel bar or a regular lever handle. They only come in black, grey or white! I was initially going with a very sleek 2 pane sliding door from Ultraline that had an integrated handle within the frame but the cost was too high for me to change it to a 3 pane. If I had the budget though I would have gone with them instead. Express Bi-folds do a slimmer framed option than XP Glide, I think it is called XP Panoramic. The 3 pane was more than Ultraline I think though. The consultant at Express-Bi-folds also advised against slimmer framed bonded glass options as if for any reason you damage the glass you have to replace the whole frame as well which is a major structural headache. Most slim framed options use this method though (as opposed to beaded - correct me if I am wrong!) so I would have chosen to ignore his advice if my budget allowed :-)
