In order to have clean air in the smoking room in the 1st and 4th floors in “GRAND TREE MUSASHIKOSUGI”, the complex shopping mall, we took 2 specific measures. Firstly, by setting the carved wall and utilizing the character of the smoke -smoke is pulled to walls- we induce the smoke to the exhaust outlet on the ceiling. Secondly, by setting the fan between the ashtray and the exhaust outlet, the secondhand smoke and smoke from people’s mouth are quickly drawn in. With those measures, the smoke is immediately cleared out from user’s breathing area. The room in the 1st floor is a 4m×3m space. By putting a white halftone dots seat on the mirror-made end wall, the reflected space including the curved wall and counter looks foggy and thus users think as if the air flows to the deeper inside. The room in the 4th floor is a sunroom with 2 walls and a ceiling glass-made and faces an external terrace which is a place of relief. The curved wall also functions to block glances from the external terrace and an adjacent mansion. Big and small halls on the wall draw in the smoke around ashtrays and bring in external lights to the inside and then give a depth to the space. This smoking room creates an effective air flow as equipment and also by a visual effect. We successfully provided a smoking experience.
