If you are on a budget, then review these small kitchen designs. Just because you have limited space, it stills needs to be functional and comfortable, since you will be spending a fair amount of time in your kitchen.
Storage space is a premium in a small kitchen design, therefore try to maximize the cabinetry and add a pantry if possible. A pantry cost less than the equivalent cabinet footprint and will provide more useful storage space. Spend the extra money for the accessories in the cabinets: sliding shelving, lots of drawers, etc. These will increase the amount of storage than having the base cabinet.
