Hi Fizzy Bubbles,
You could have more pantry shelves and have it in there if you want more benchtop space.
Just a couple of ideas for you, in the ensuite have your bench all the way across, that allows for more cupboard space. And more shelves in the linen, you can't have too much linen storage lol.
Your plans look great!
Hopefully we're not that far off having our slab down! Fingers crossed it's soon!
