The characteristics of Gwenael Nicolas' design are translucency, emotional coloring and attractive forms. When you come to use the products or encounter the spaces, you realize the designs are not just about superficial beauty, but that considerable thought has also gone into their functionality. The design originates from a story board with subjects as the central focus, then he incorporates an element of discovery and unpredictability in the design. Each project is created like a perfume with a first, second and third note. at first the design seems cool and abstract, but when you interact with it, "surprise" something unexpected happens, and a smile appear on your face. Finally the more you use it the more you feel attached to it.
