This forest-surrounded vehicle research and development facility is a hub for the company's mission of "continually making better cars. Based on the concept of "spinning thread", the origin of the company's business, the external shutters are made of extruded aluminum profiles, crossed in the front and rear direction, like spinning threads, and have the function of shading, while their spindle shape directly reflects the company's brand concept. The interior design creates a unique space for this site, focusing on the densely forested on-site environment and the issues inherent in it.
