What differentiates a truly stunning, minimally designed interior from one that’s just not full of a lot of stuff? From a room that’s sophisticated and rich rather than plain and boring? Creating simple spaces isn’t hard, but it does require a particular balance of key design ingredients to make the right minimal mix.
When a space doesn’t have a lot of actual items in it, you have to be even more strict with basic design rules like balance, proportion and harmony. Furniture should all be in proportion with itself — meaning nothing sticks out as too big or too small. The visual weight of a room should be balanced (meaning one side doesn’t feel too much “heavier” than any other side).
There should be harmony among your furnishings; not everything has to “match” but they should complement and coordinate. And of course, if you are going to add something too big or too small for dramatic effect — go either really big or really small to exaggerate that you’re doing something intentional.
