Each element in this design is a rectangular wood strip of the same length. The width of the strips begins at 4cm and decreases gradually as the structure continues up. Structurally, the tower is organized in two perpendicular axes, crossing at a central datum. In both axes, the strips bend in an alternating pattern as they go up, switching direction at each bend’s apex. Within each axis, the strips notch together when they cross. When the two axes cross at the central datum, they weave through each other. This weaving joint (along with the surrounding bent strips acting in tension) gives the structure its stability. An “X” in one axis weaves through an “eye” in the opposing axis. The angles of each “X” determine and stabilize the position of the “eye” that encapsulates it. As the width of the strips decreases, the radius of the “eye” increases. This causes all the strips around it to increase in radius, becoming thinner in overall plan diameter. Therefore, as each section’s strips get thinner, that section of the tower gets taller.
