The Chikushi Gas showroom near the station tells the benefit of lives with fire through its facilities and town-opened activities. The uniquely shaped fireplace is centered in the space as a symbol, giving the fire warmth, and the calm atmosphere gently spreads to the surrounding. We reinforced the spread of warmness and brightness with artificial lighting impressively. In the grand stairs, we were conscious of reproducing the natural rays with intense lighting, like sunlight coming in from the top.
