The ‘tube houses’ that dominate Hanoi’s streets

HANOI (AFP) – Tall, thin and brightly coloured, Hanoi’s “tube houses” dominate the city’s streets as nine million people compete for space in Vietnam’s bustling capital.

Although Vietnam saw a number of villas and garden houses built during the French colonial period, Hanoi has few of these grand residential homes.

Instead, tree-lined streets are packed with dwellings that are barely four metres wide, but are three times that in depth.

Typically, a tube house might be home to a family of four but two or three generations of relatives sometimes have to jostle for space.

The first tube houses – known as nha ong in Vietnamese – are thought to have appeared in the capital at the end of the 19th Century, when villagers looking to sell silver, traditional herbs and tools began to move to the area.

A narrow architectural style evolved from the limited available space, said senior lecturer at the National University of Civil Engineering Tran Quoc Bao.

The design is still a favourite in modern day Hanoi, where architects now refer to them as “adjoining houses”.

“This model of house is essential for an urban architect (today). The adjoining house is a combination of both the traditional and modern residence,” the Hanoi-based lecturer told AFP, adding that they can also be found in many other Vietnamese cities.
