Officials in Hanoi presented two design finalists, on Thursday, for the proposed 22-hectare Thang Long Theater.
The two plans during a government-sponsored design contest held to generate ideas for the theater which is slated to be built in the new urban area to the west of Hanoi's West Lake.
A ground-breaking ceremony will be organized during Hanoi's millennial anniversary which will take place between October 1-10.
One of the design situates the theater in a lotus pond and capped with an expansive roof that resembles a tortoise shell. The surface of the roof is patterned to resemble dragon scales.
The other design features a structure meant to evoke a red sail coasting along Ha Long Bay.
According to the Hanoi Department of Planning and Architecture, the theater will include a 1,200-1,500-seat section for classical concert performance and a multi-functional performance section of 1,800 seats. In addition to the two main concert halls, the building should feature spaces for exhibitions, fashion shows and an outdoor performance area.
The construction will mostly rely on steel, glass. Glass water pipes will be used to reduce heat radiation, the department said.
So far, most concerts and art performances in Hanoi are organized at the 900-seat Hanoi Opera House located near Sword Lake. Early this year, Hanoi opened the Au Co Art Performance Center with 730 seats.
