The Crown Point site above Burnley, with a brick shed and two radio masts, has long been an eye sore visible from the surrounding towns. Our proposal replaced the shed and the masts. To maximise visibility, the base was raised by building on the lower part of the brick shed. The top half of the shed was demolished, the rubble formed the hard core onto which a concrete base was made. The mound was then covered with soil and turf. New fenced paths were created through the boggy landscape.

The tubes are arranged in such a way that the weight of each layer is transferred by steel rings to that are bolted together by horizontal bolt in shear to the layer below. The rings also act to tie the tubes in each plane to each other. As the layers are rotated slightly one to the next this twist provides horizontal in-plane bracing. The ends of the tubes simply cantilever past the lines of support provided by the rings-in effect the rings and tubes provide a load path for the weight of the tubes down to the foundation.

Mild steel comes in a variety of size with walls of variable thickness. This gave us the variability to develop the structure and sound. Being heavier, the fabrication process is more difficult but the weight helps with the mass required to resist overturning under wind load and live loads and due to the asymmetric form. Unlike stainless steel or aluminium, mild steel can be relatively cheaply welded. To prevent rusting the steel will need to be galvanised. This will give a shiny appearance when the construction is new, and will dull slightly over time while still reflecting light in an interesting way.
