If you have room, a walk in larder is fabulous. I had one before, but don't have space now, so I have a larder unit with pull out drawers in my new kitchen and love it to bits. It's only 50cm wide, but holds so much, and it's so easy to find everything.
On a similar note, drawers rather than cupboards wherever possible.
If you don't need them, I'd do without wall cupboards, but that's mainly personal choice as a very short person, plus I think they make kitchens look smaller.
As a short person, when we finally choose our final house, I will have one area of lowered work surface, as I find, for example, rubbing in for pastry, or mixing things in large bowls and such like quite difficult on a normal height one.
Double, or at least 1.5, sinks are very useful if you have space.
Get lots of people to come round and design things with you, and then go to somewhere like DIY Kitchens and buy it for a quarter the price. You can show them a design and they will tell you what to buy, and it's all done online.
Get a really really good fitter, because that's what makes real difference to how it looks and works.
Alternatively, get a local independent company to work with on the whole process.
