The panels of Wonderwall are constructed out of strips of reclaimed wood. The strips of wood species suar, teak, meranti, and bekirai java wood are combined at random, and used with the raw, uneven sides to the front. The strips are interspersed with openings. The intense natural weathering and erosion of the wood provide a raw texture. After mounting, connection lines between the panels are hardly visible. Each panel is handmade. The tiles are treated for insects, a fire retarding treatment is optional. The dimensions of a tile is fixed are 15 x 60 cm, with 7.5 cm cut out. Wonderwall Train can be used for interior and exterior applications, but exterior wear and tear will be quite severe.
