Patio - Level with Indoor tiles or Not?

[Triassic]

I'm about to starting to lay the hardcore for the patio and wondered what your thoughts are on laying it, so that the finished outdoor tiles are level with the indoor tiles. I worry that in the age of torrential rain that I'm asking for water ingress issues. Maybe drainage is key?

The alternative is a step down from the patio door onto the patio.

Your fine doing that 

But I would always put an Acor across the full length of the doors
