Jj, Aston Works does this to a certain degree. You can get a donor chassis and they will build whatever you want but normally a rebuild of an old classic.
This service normally costs between £300-500K. In theory they could expand this to a more custom nature of modern cars but I am not sure the demand is really there.
This is also how Zagato started back in the day and they still make models for Aston look at the Shooting brake.
I think Aston have a good custom build and specials structure that actually is superior to any other brand with Ferrari on a similar level.
