As you can see in this exclusive spoiler Jodie Whittaker has a more organic tardis in Series 11. The steps look ornate, almost victorian.

I would say that the new Tardis will be more like the 8th Doctors, very grand and Victorian. For what I can make out of the Tardis Console it looks like it nods back to the old style one.
