During the designing process, the interior designer makes hundreds of decisions from the first idea to the last drawing. So, there is a need for a control principle: a concept that rules every detail. Without this, only ’ad hoc’ decisions can be made, so the end result will not be harmonious.

When we see a nice house, we’re not going to tell you how good the concept was, just seeing how simple the solutions are. If this control principle is missing, we will not see the house as nice.

The concept is eventually the style itself. For example, for Gothic, it is light, for historicism is to discover and improve the architecture of old ages.

But we don’t have to go that far: in fact, we need a concept when designing our lunch or our daily outfit. There is no life without concept.
