FURNISHING A SMALL KITCHEN: CREATIVE AND FUNCTIONAL IDEAS

In any case, some things are essential, even in a small kitchen, such as a refrigerator, for example.  Nowadays there are plenty of compact, energy efficient solutions on the market so that even a restricted space can house a decent sized fridge. The space under the sink is useful for this, as well as a tall unit or wall unit. The important thing is to calculate the right distance between the fridge and sources of heat such as ovens.
Speaking of ovens, also in this case there are several compact built-in solutions, but you could also consider an alternative, such as a countertop electric oven or air fryer that can be stored in a cupboard and brought out as and when needed. They can be placed temporarily on the worktop or a cooking hob not in use, taking up space only when necessary.

An induction cooking hob is ideal where space is at a premium because when not in use it provides a linear, easily cleaned surface on which to place things.
The sink bowl can be covered with a mobile worktop to add work space.
The kitchen back panel can also become a practical storage wall on which to fit kitchen roll holders, utensils, spices and condiments.

What about a dishwasher? We often forgo this appliance in a small kitchen, convincing ourselves that a sink is enough for dishwashing.  
Actually, in a small kitchen, without this appliance there’s a risk of creating untidiness, not to mention of consuming much more water to hand-wash dishes. Also in this case, there are compact models that can be built-in or stand alone connected to the sink drain, which wash place settings for four or six people, rapidly and effectively.
