The Seoul Metropolitan Government has announced an international contest – judged by David Chipperfield – for a new £821 million transport hub in Gangnam
Open to teams of architects, urban planners, civil engineers and transport consultants – the competition seeks ‘creative and innovative’ proposals for a 150,000㎡subterranean mass-transit hub under Youngdongdaero boulevard (pictured) within Seoul’s popular Gangnam District.
The winner of the £10.27 million design contract will draw up plans for a new mixed-use complex featuring an integrated railway and bus station alongside car parking and new public and retail spaces. Planned to complete in 2023, the project will be constructed beneath a linear 56,000㎡ site located between Samseong Subway Station and Bongeunsa Subway Station.
According to the brief: ‘The goal is to establish a global communication and exchange centre at Youngdongdaero, which is already planned as the site where six metropolitan railway lines will converge, by developing the area into a mass transportation hub and multi-purpose people-centred space.
‘The project site is a major artery that moves and connects the flow of traffic to and from Gangnam to the northern part of the Han River. All public transportation, such as taxis and buses, travel on this 70-metre wide boulevard. In addition to being a main thoroughfare, at times, traffic is blocked in order to transform this space into an urban piazza, making room for street parades, K-Pop concerts, and other major events.’
Located in south Seoul, Gangnam is one of the 25 districts which make up the South Korean capital. The wealthy area is home to around 527,641 residents and is well known due to the music video ‘Gangnam Style’ by artist Psy which was filmed locally.
The prominent Youngdongdaero boulevard connects Samseong Subway Station and Bongeunsa Subway Station and features a number of underground shopping malls and car parks. Nearby landmarks within the emerging Seoul International District include the COEX convention centre and trade tower, and the Jamsil Sports Complex.
The new transit hub will bring together six railway lines which converge in the area and is expected to occupy up to six levels below street level. Between three and seven teams will be invited to participate in the competition following an open call for applications.
Bids will be assessed 50 per cent on team composition, 15 per cent on prior experience of similar projects and 35 per cent on the design concept. The competition languages are English and Korean.
Judges include David Chipperfield, principal of David Chipperfield Architects; University of Seoul professor Youngchan Kim; and Haeseong Je, chair of Korea’s National Architectural Policy Committee.
Three to seven teams will be shortlisted following an RFQ and will then be invited to submit design proposals for the contest’s second stage. The final winner, to be announced on 20 October, will be first in line for the project’s estimated £10.27 million design contract. Six shortlisted teams will also receive an honorarium worth around £70,000 each.
The deadline for applications is 5pm local time, 21 June.
