DH fitted out an old cupboard as a larder copying some ideas from those posh ones -it's quite functional but its a good concept and amazing what you can cram in.
3 half-depth shelves at the top for jars, packets etc
Spice racks inside doors, one side narrow for tiny jars, the other deeper for things that are not heavy (gravy granules etc). (Mine are just wire ones from ebay).
Then a full depth shelf at about worktop level, another shelf and the cupboard base gives you three tall spaces for cereals, wine bottles, big containers and the veg box. I think the larder in the OP's link doesn't make good use of its lower space TBH!
I have another base unit with pulling-out inner drawers that takes some overflow of pasta packets, baking stuff (like this). They are lots more accessible than if they were on a deep shelf. If I'd had a slightly bigger larder cupboard I might have put one or two similar shallow-ish drawers inside it for those though.
YY to plastic tupperware and lunchboxes in a wicker basket, excellent poncey way to hide the hideous things. Also they are nice for tea towels but Pag is right you don't want to find a mouldy courgette has managed to hide from you in the bottom of one.
