国家体育馆副馆

The Auxiliary Hall of the National Indoor Stadium sits within the National Indoor Stadium at 9 Tianchen East Road, Chaoyang District, in the southern part of the Olympic Green between the Bird's Nest and the Water Cube, part of the trio of principal venues that define the park. The main arena was completed in November 2007 and hosted gymnastics, trampoline, handball and wheelchair basketball at the 2008 Games; after a refit between 2018 and 2020 it became a dual-Olympic venue, staging men's ice hockey and para ice hockey in 2022. The auxiliary hall is a separately operated secondary space used for training, rehearsal and smaller events. The hall offers 3,000 square metres of floor on a 50 by 60 metre plan, with 25 metres of clear height and 20 metres to the catwalk, seating for 1,800 and supporting VIP rooms, boxes, function rooms and parking. That scale accommodates combinations of basketball, volleyball and badminton courts, or a stage and exhibition build. The operator states explicitly that post-Games the hall is meant to work alongside major events in the main arena, taking cultural programmes, small sports competitions, television recordings and business functions. The refurbished main building has about 97,836 square metres of floor area and roughly 18,000 seats including 240 in the training hall, and the auxiliary hall shares its foyers, security screening and loading facilities. Architecturally the main arena is known for its alternating folded-fan metal roof and glass curtain wall; the auxiliary hall continues the same silver-grey metal and glass language, sitting low beside the parent building with a shallow double-pitched curved roof over a column-free interior. The stadium is operated by a company under the Beijing Performing Arts Group and, besides ice hockey, figure skating and short-track training, hosts concerts, esports and brand launches. Aolinpike Gongyuan station on metro line 8 opens within walking distance of Tianchen East Road, line 15 serves the same interchange, buses run along Beichendong Road and the North Fourth Ring Road, and the campus has centralised parking and security entry.
