The MegaDome tent was designed by Special Structures Ltd, which is collaboration between Rudi Enos Deisgn Ltd and AWD.
The Structural design was completed with NDN Membrane, a Finite Element Analysis software package. The structure is a composite cable net; more than 15000 metres of reinforced polyester webbing were used to support the membrane.
The structure has the largest clear area in front of the stage of any portable structure available for hire. The six King Poles in front of the stage form a 50 metre (164 feet) circle with a clear distance of 62 metres (200 feet) in front of the stage. At the Reading Festival there were more than 30,000 people in the structure enjoying a clear view of the performances.
