When you live in a small space, you need to make your furniture work extra hard and no where is this more important than your kitchen. 
Look for kitchen units that are devoid of fancy gadgets. Whilst magic corner units, for example, might look great and make life easier, they often steal valuable storage space from the unit itself, space which you can not afford to sacrifice. Likewise drawers, often provide less storage space than shelves in the same area.
Try to find pieces of furniture that provide more than one function:

I spent ages searching for a kitchen bookshelf that was deep enough and sturdy enough to support our wide cookbooks. This unit from Ella's Kitchen Company does just that and more. By moving our dry foods to the cute scoop drawers, I've freed up a whole shelf in a kitchen cupboard and the hooks make a pretty decorate display area. I ordered it unpainted and painted it to match the rest of the kitchen.
