The new theme song doors line the collaboration between the company Bertolotto Porte and the well-known architect Gianni Arnaudo. Models inspired by the theme of nature capable of furnishing the rooms with a unique style. The concept of irreverent collection compared to the parameters that determine the value of the door and that composes. The "rigid symmetry," as defined by the designer himself, is abandoned. The striking effect that comes to an avenue in perspective or fantastic wood. Everyone can play with their imagination, thus giving freedom to the imagination. As suggested by Gianni Arnaudo "into the new world brings."
