Interior Space and Exhibition Design Hight To Hight Head Spa And Hair Spa by Wensong Wang Hight To Hight is a head spa and hair spa interior located in Shenzhen. The design draws on Southern European culture and on the symmetry and proportion of Ottoman architecture. Walls and floors are finished with distressed cement art tiles. Glass mirror surfaces widen the space and create changing light and shadow. Arched door frames are accented with slim metal lines. The interior is divided into three zones: an aroma healing area, a bar socializing area and a cultural gallery. Vintage lighting adds a warm and calm atmosphere.
