In Vietnam, the history of cities can easily be seen through their urban patterns, landscapes and housing typologies. Most recently, the economic
reform in 1986 has resulted in huge impact on the Vietnamese society. The rapid economic growth and privatisation of the market has resulted
in the appearance and significant development of the “new tube house” which soon became the most dominant housing type in Vietnam. Hanoi,
the capital city of Vietnam, has a long history and also is very rich in architectural styles and typologies which are reflected in its urban pattern.
However, there is no actual clear boundary in urban scale as the new tube houses are scattered all over the city and they are adapted differently to
the contexts. This paper aims to investigate how the traditional urban tube houses in Hanoi transformed into the new tube house and, on the other
hand, present the results of a survey conducted in Vietnam on how these houses respond to the Vietnam local climate and perform in terms of
energy consumption.
