“Unkai” means sea of clouds in Japanese.
We designed extension wing of existing ski gondola station includes cafe space and deck terraces. Since the site is Located in the middle of steep slope in Mt. Tomamu, over hanging deck terrace is supported with cantilever beams in order to minimize construction area.
From the deck terrace we can overlook excellent view of Unkai in summer and frozen tree landscape in winter.
