Detail: Lattice Roof, Onagawa Station

摘要

It only took minutes for a tsunami wave to reduce Onagawa Station in Miyagi Prefecture, Japan, to a pile of rubble on March 11, 2011. Four years later, a new train station by Shigeru Ban, hon. faia, opened about 500 feet inland from the original building footprint. Topping the three-story, 9,682-square-foot structure is a gently sloped, white membrane roof, inspired by the outstretched wings of a seabird and supported by a wooden lattice, a signature of Ban's work. The lattice comprises laminated veneer lumber (LVL) arches made from Japanese larch. Yasunori Harano, project architect for Shigeru Ban Architects, and his team worked with local timber subcontractor Key-Tec Co. to slice the 3.5-inch-deep LVL beams lengthwise to warp each half to the desired curvature and roof height, before layering them back together during the construction.
