Year 2010
Location Hanoi, Vietnam Context Future arc comeptition - international competition Area 6000 sqm Program link land, sustainable residential, market in the river Team Le Quang, Hoang Phuong Lien Status Citation The Red River flows from southwestern China through northern Vietnam to the Gulf of Tonkin. Once reaching the lowlands near Viet Tri city, the river and its distributaries spread out to form the Red River Delta. The reddish-brown heavily silt-laden water gives the river its name. The annual silt volume is approximately 100 million tons or about 1.5kg/m3.Thus, the delta is a major agricultural area of Vietnam with vast area devoted to rice. However, Red River is also notorious for its violent floods with its seasonally wide volume fluctuations. The local life, therefore, is badly damaged. That’s why it is essential that the land is protected, but yet there is no empirical solution. |

1.RED RIVER
The site is at the capital city. It has a thousand-year history and is always the sacred land of VietNam
It was developed from riverside agricultural and handicrafts villages along the river.They formed traditional urban units of ancient city - PHUONG or guild
The site is in close promixity to the old streets quarter. It is near the city cultural and political center and the intersection of city urban development derection until 2030. It locates in the biofuel source area.

Site Analysis
GROUND_HIGH LEVEL CLASSIFICATION Permanent water level(100%S) Maximum water level(60%) Lowest water level(150%S)
In Vietnam, there are 2 main seasons: dry season and rainy season. Annually, rainy season lasts from May to November while dry season lasts from December to April. For six months of rainy season, 46% of the Middle Bank section is flooded, causing great damage to local life. In dry season, it is often available but still the dilemma is that the dry river implies difficulties in river traffic and economic development.
2.PROPOSAL
|
1. First, we dig canals to increase the river ‘s volume. The dug soil would then be used to bank up the river, improving the site’s altitude. Thus, the site is guaranteed to be above water level all year round.
2.Setting canals in an increasing order will not only extend precipitation volume but also facilitate agricultural activities. 3.Create an area spanning 1,000 kilometres around the construction site with inclusive resource zone from which energy, food, water and materials can be easily accessed. |
3.Masterplan
In this project, the construction site is chosen to be Bãi Giữa (“Middle Bank”) - the low-lying land in the middle of the Red River under Long Bien Bridge.
To the north of the chosen site lie a plenty of traditional handicraft villages, as well as old streets – Hanoi cultural center to the South, West lake along with ecotourism sites to the West and Gia Lam district to the East which is the new orientation for urban development. However, despite that strategic position, the area of Middle bank is still abandoned for years, leaving the local residents in drifting cottages, vulnerable to flooding season.
In this marginal space next to the city, around twenty migrant families living in floating boats and beneath ragged huts occupy the area. They come from different parts of the country, lacking legal status, vocational skills, and adequate income. Many make their livings as garbage collectors. Life in this small community of Middle Bank means facing the seasonal flooding of the river, a lack of stable employment or regular access to basic social services, as well as negative perceptions from the wider society.
