The Olympic Delivery Authority (ODA) has unveiled the designs for the London 2012 handball arena.

Designed by Make Architects with PTW and Arup, the arena features retractable seating for up to 7,000 people, as reported by CJ last week.

The copper-clad building will feature a concourse level with glazing that allows visitors outside to watch the events inside.

100 light pipes in the ceiling will allow natural light into the venue, while a rainwater harvesting system will flush toilets with water from the roof.

In legacy mode the venue will seat 6,000 and be used for five-a-side football, netball, basketball, volleyball, badminton, table tennis, handball and Futsal.
