The structure's function is as a landmark structure supporting the back-lit advertising panels. It is located very close to a busy road system at Bow in the east end of London. The central D-shape is in-filled with a single large fabric panel and the lattice steelwork forming the D was also clad in fabric. During the engineering and detail design phase, the designer's concept was modified to accommodate the local wind conditions. Tony Hogg Design engineered, fully detailed the steelwork and fabric and produced the fabrication drawings.
