New floor height will not match height of the existing floor

[EViS]

I am undertaking a garage conversion and have a problem with floor levels. There will be two entrances into the converted garage from two different rooms (one to the side, one to the rear). However, the floor in the rear room (Floor A) is 30mm higher than the floor on the side room (Floor B).

What is the best solution to overcome this issue? I believe my options are:

a) Slope the new floor in the garage to meet the height of the two existing floors. Would 3cm over a span of 3 metres be noticeable when walked on and when furniture is positioned?
b) Create the new floor at the height of one of the existing floors and create a 3cm step in the door to the other floor.
c) Install the new floor at a height in between the existing floors (i.e. 15mm lower than Floor A and 15mm higher than Floor B).

Which solution, or any others, would be most suitable?

Slope it or use chamfered doorway threshold strips. 30mm won't have an effect as long as it is done uniformly, i.e. don't jump up in the last 450mm.

Could you not deal with the floor level issues by clever use of flooring materials?

Will a 30mm slope truly not be noticeable over that distance? And if using chamfered thresholds, do you reckon that plan c) would be best?

Could you suggest some? The idea is to lay laminate or solid wood right across Floor B and the garage (once complete).

Just have a 15mm chamfered threshold strip under each doorway.

How common is it for houses to have such differing floor levels?

Older houses normally more uneven rather than differing per se, newer houses not really (not on purpose anyway .
