Buy a combined appliance. If you can’t fit a separate fridge and freezer or washing machine and tumble dryer in your kitchen, consider buying a combined fridge freezer or washer dryer instead. This will give you a huge space saving without losing any functionality, and with a washer dryer you can even set a load to wash and dry in one go. Refer this link to know more:
