Eton Manor has a history as a sports venue, and this new iteration was built as a training facility for the 2012 Olympics, complete with a temporary space for aquatics training. Nine competition tennis courts with seating for 10,500 spectators will serve as the venue for the Paralympic tennis events.

Future Use: After the Games, Eton Manor will become a permanent sports complex with tennis and hockey facilities, and seating for 3,000 spectators.

The Velodrome was the first venue to be completed, 18 months before the Games. It seats 6,000, and both the track and exterior cladding are made from FSC-certified wood. The building relies on natural ventilation and its roof harvests rainwater that will offset its water use by 70 percent.

Future Use: The Velodrome will fall under the jurisdiction of the Lee Valley Regional Park Authority and, with the neighboring BMX Bike track, form the center of a new VeloPark for community use and to train competitive athletes.

The Riverbank Arena has one competition and one warm-up pitch, which share a blue-and-pink color scheme. This marks the first time that Olympic hockey pitches aren’t the traditional green—a change that will make the yellow ball easier to spot.

Future Use: The pitches will be moved to Eton Manor, at the northern edge of Olympic Park, to be part of a permanent sports complex.

Twenty-thousand square meters of recyclable PVC fabric were used to clad the temporary 12,000-seat Basketball Arena, and will be used as a platform for lighting displays during the Games. The PVC is stretched over a modular 1,000-metric-ton steel frame that was erected in just 3 months.

Future Use: Essentially a giant flat-pack structure, the arena will be dismantled after the Games. There is speculation that the entire venue will be shipped to Rio de Janeiro for use in the 2016 games.

Wrapped in silver-toned PVC and topped by an inflatable roof, the Water Polo Arena seats 5,000 and boasts a 37-meter competition pool, plus a smaller training pool. It has the distinction of being the first bespoke water polo venue ever designed for an Olympic Games.

Future Use: Designed as a temporary venue, the arena will be deconstructed after the Games. Many of the building components, including the seats, were rented so that they can be returned and reused.

The Copper Box, which will host the handball and modern pentathlon competitions, can hold up to 7,000 spectators on retractable seating around a 2,750-square-meter playing field. The building’s name is inspired by its cladding—3,000 square meters of sustainably-sourced copper. The arena’s roof is pierced by 88 light pipes that bring in natural daylight to help offset energy use.

Future Use: After the Games, the Copper Box will be turned into a community sports center that will seat up to 6,000 and offer activities ranging from basketball to wheelchair rugby. A café and fitness club are also planned.

Hadid’s office says that the design of the center, which can hold 17,500 spectators, is inspired by the geometry of water in motion. It has a minimal column structure along the 160-meter-long roof to avoid interrupting sight lines. Featuring three different pools and a warm-up area for divers, the center will host the swimming and diving events during the Games.

Future Use: The building was designed to be scaled down to hold 2,500 in its post-Olympics capacity as a public aquatics center.

This lightweight steel structure is the central venue of the Games. As the largest structure built in Olympic Park, holding 80,000 spectators, it will host the opening and closing ceremonies, as well as many of the track and field events.

Future Use: After the Olympic Games conclude, the stadium will be scaled down to leave just the lower, permanent seating tier, which holds 25,000. The deadline for bids for reuse has been extended until late July; the goal is to sign construction contracts at the end of October and have the reconfigured stadium reopen in 2014 under a 99-year lease.
