Would you recommend the doors to be made of one piece of solid wood slaps?!

I wonder if anyone here has seen something like this, that a door is made of one piece of solid wood, I did a research and found that solid wood slaps are extremely expensive, in a UK website they were sold for around £5000 each that the size is a bit bigger than a door size. My concern is that it can bend or twist by time. 

I am just guessing, but I think a solid piece would be good and wouldn’t twist over time since it’s so thick and especially if you have some type of sealer so moisture doesn’t penetrate the door.  I would love to have a solid one piece door but your right, they are expensive.

A door made from a single slab of solid wood does exist, but you’re right to be cautious. Large, one-piece timber is rare and very expensive because of how hard it is to source and season properly. Even with high-quality drying, a solid slab door is much more prone to warping, twisting, or splitting over time as it reacts to changes in humidity and temperature. That’s why most external and internal “solid wood” doors are actually constructed from multiple pieces of timber, often engineered or laminated, to give the look of solid wood but with much better stability. If you want longevity without spending thousands, an engineered solid-core door with a hardwood veneer is usually the smarter choice.

I think I would use a slap that is stored by myself in a very dry place for long time like 2-3 years and see if it cracks, bends or not, then use it and probably you need to do CNC machining on both side to take the bends off. I have seen those ones you mentioned and they are not bad I would say, you can cut them to the size you want and I think they are FD30 in general.
