Westfield, Chestnut Plaza Azure Hypar

The design is based on Fabric Architecture’s Azure Hypar at Chester Racecourse. The beauty of the Azure is that it can be modified to suit different locations and requirements. For Chestnut Plaza the central mast was removed from the design to maximise the area under the canopy. The four remaining masts were fixed to the steel super structure of the underground car park below. The Azure’s curved cross members were replaced with robust but lightweight trusses to hold the extra loads needed for performance equipment. The trusses also accommodate the integral rainwater management which carries water from the canopy, through the masts and into drainage channels. PVC type 2 fabric was used due to the size of the canopy. It will require annual maintenance to keep it sparkling but if maintained properly the fabric is expected to last for at least 20 years.
