So I'll give my two cents too :) Splitlevel, if you like it. It's perfectly fine if it appeals to you. I assume you have thought about all the pros and cons.
An access from the garage to the house can definitely make sense, but to the pantry?
1. Exhaust fumes might get in when you open the door – food...
2. The pantry then becomes a dirt trap. Where should you put your clothes and shoes? In the garage or only later in the cloakroom?
3. The passage is simply too narrow with a shopping basket and especially with a baby carrier, toddler, diaper bag! Better to plan a generous roof from the front door to the garage or mirror the ground floor and plan access in the other rooms.
The cloakroom gets cramped. With 2 children there are tons of shoes, jackets, sports and school bags hanging there... In the end, everything ends up in the hallway.
Also, the cloakroom is poorly accessible – the same applies to the toilet!! – and in the end, hardly anything really gets put there. I'm speaking from experience ;)
That means things end up hanging or lying somewhere else!
And as I said, the access to the toilet is not optimal. Hiding the cloakroom twice doesn't help if every guest who needs to pee has to pass it.
If there are no children yet, placing the large bathroom is very impractical. Children need help bathing for several years, later also when showering. And on the toilet, of course, and when brushing teeth...! So why hide the large bathroom? I am not a fan of a parents’ bathroom and a kids’ bathroom. Of course I support having a second bathroom. We will have that too, but on another floor with the two older sons (8 and 12) in the attic. Nevertheless, the large bathroom on the upper floor is freely accessible for everyone – for the parents, for the youngest, and also at any time for the 2 older ones! Everyone can use it. At any time! This separating through the bedroom always gives me the impression that children are not welcome here. How will children see it later?
Long story short: a second bathroom is definitely useful, but the large bathroom should be freely accessible for all family members. Better a shower bathroom for the parents!
Otherwise, I quite like it. Views wouldn't be bad regarding window arrangements etc.
