I would contact flooring manufacture and ask them

Hi Lainie No Problems! Getting a floor transition off the shelf or made up is no big deal. Most flooring companies will be able to supply this or a good chippy can knock it up for you without a lot of fuss. Essentially you just match the timber species and apply a little floor polish. If you contact hardwood flooring distributors in your area such as Launstein , you will see what they have (or can make up for you) quite simply. If you scroll down the page in the link you will see a sample of exactly what the builder needs. Often flooring companies are best equipped to make up something like this in eg a special size as they do it all the time. As to it being 'another work scope item', any decent general contractor would have been doing this in the first place as it is an off the shelf item. Even if they couldn't get the right width, it should have been a conversation with you as to what other solutions were available ie having one made up. Regarding how it should be done to fix it now, I would be pulling up the tiles in the doorway and replacing them as they won't be able to cut it down neatly. I would then cut back the screed and reinstall properly cut tiles with a trim edge like below.

What you make the transition out of is up to you, but either way once the tiles in the doorway are properly finished you can decide what you like. Personally I would do the matching timber as it then disappears altogether. Good luck! Cheers

providing the underlying structure of the floor is suitable you can run the floor boards in the any way you want and widthways boards in the hallway should make the space feel more spacious as it flows the same from inside to out and the herringbone floor would seem a little fussy unless it's a formal front entry
