I'm trying again without a pantry... [...] it's just not that easy to let go of certain ideas
One shouldn't let go of some ideas either, even though I basically welcome you "loosening up" in this regard. You can never get all wishes fulfilled at once, or you just hinder yourself with them. But simply striking them out shouldn’t be done lightly either; instead, one should classify their wishes into "must," "would be nice," etc.
The pantry would not really be a major sticking point in my most recent proposal, but: without it, the utility room would be so much smaller that without reducing the guest/workroom, a wardrobe space would come out of it.
By the way: in my most recent proposal, it could easily be moved to one of the northern corners of the utility room.
I am a fan of the classic pantry (especially for foodstuffs that like a constant, almost cellar-like climate). That is, on one hand, I am not a proponent of the pantry as a storage room for excessive bulk purchases, and on the other hand, I find your view of separating it from the heating room correct.
But however one is inclined: I know this is probably a matter of personal preference. And I’m not a big fan of "re-education." The same applies to the wardrobe: it is your house, and if you are okay with leaving clothes in the workroom, then don’t build a formal wardrobe in your house just because of the opinions of fellow discussants in a forum.
