The final design has been developed to allow for a more stable design. The supports have an added surface area at the top to disperse the dead-weight of the panel roof more evenly. The axis on the supports has been re-defined with a wider base to create a more even structure the roof has been extended to allow for adequate cover from the elements and the slant is less accentuated to prevent the structure from tipping over on one side. A smooth curve has been added to the concrete platform to permit access to wheelchairs and allow further ease of access. There is a centre table to allow users to place their drinks and free their hands whilst smoking, and below this there is a cigarette tray to dispose of cigarette ash and cigarette butts. At this point it was discovered chipboard would be the least suitable material to use for the roof, as it is almost impossible water-proof therefore it has been suggested marine plywood is to be used for the roof-cover. This material is more expensive but it will never rot and therefore the structure could be re-used in future events.
