Three rules for making good design are:
Functionality: The design should be functional and meet the needs of the user. This means considering the intended purpose of the space and the activities that will take place there and designing the space accordingly. For example, a modern living room interior design should have comfortable seating and enough space for entertaining. In contrast, a kitchen should have ample counter space and storage for cooking and meal preparation.
Aesthetics: The design should be pleasing to the eye and harmonise with the surrounding environment. For example, a bedroom should be designed to be a peaceful and relaxing retreat. In contrast, a dining room should be designed to be formal or casual, depending on the desired atmosphere.
Sustainability: The design should consider the environmental impact and be sustainable in the long term. This means using materials and products that are environmentally friendly, as well as designing the space in an energy-efficient way.
