An open international ideas competition has been launched for the £60 million regeneration of a disused nuclear bunker in Busan, South Korea
Backed by Busan Metropolitan City and site owner Kyungdong Construction – the contest seeks ‘creative and unique’ proposals for the 4,330m² underground structure.
Located in the foothills of Hwangnyoengsan Mountain, the abandoned complex was constructed during the Japanese colonial era and significantly expanded in the late 1960s.
The project – which also includes a 134,663m vacant plot above the bunker – aims to kick start regeneration in the wider area where Kyungdong Construction owns 13 million square meters of land.
According to the brief: ‘The basic plan is to interconnect the bunker and the ground site to develop a creative and unique place worthy of becoming a famous sight in Busan.
The document continued: ‘It is hoped that the program proposed will contribute to the development and improved socio-cultural publicity of the community. It is also expected that the proposed program concurrently takes into consideration the financial feasibility of the plan in terms of actual development and operation.’
Nearby visitor attractions include the mountain’s beacon tower and observatory. The site – which borders the high-density and low-income Mulmangol village – is also close to Busan City Hall and public transport facilities.
Busan is Korea’s second largest city after Seoul and is home to around 4.6 million inhabitants and the world’s fifth largest seaport.
Snøhetta won a high-profile contest for the city’s new opera house in 2012 and SYNWHA Consortium won a seperate competition for a new 27 hectare waterfront park last year.
Other landmarks in the city – which is home to the Busan International Film Festival – include Coop Himmelblau’s $150 million Busan Cinema Centre complex.
Organised by the Busan International Architectural Culture Festival, the latest contest is open to all architects, designers, urban-planners, artists and students regardless of experience.
Proposals may integrate existing cultural events into the building programme and submissions may include sketches, paintings, models, 3D images, collages and other formats.
The winning team will receive around £35,000 and an invitation to develop detailed designs. Any overseas or non-architect winners may be required to partner with a qualified local firm to deliver the scheme.
A second place prize of approximately £20,000, third place prize worth £7,000 and four honourable mentions of £3,500 each will also be awarded.
The registration deadline is 20 May and entries must be submitted by 6pm local time on 30 June.
