Show moreIn 1986, the ‘Economic Reform’ had brought significant economic success to Vietnam. The cities such as Hanoi, HoChiMinh City, and Danang, expanded enormously, and building activities increased to accommodate population growth and housing demand. The rapidly increased income allowed middle-class and upper-class families to pursue their dreams to own a private home. However, most housing projects were built without any city guidelines and lacked thoughtful design. [5] Because of high land prices and valuable frontage for business uses, most new private buildings and houses, 3 to 5 stories, were built to maximize their footprint, on very long and narrow frontage properties. Many of these infill houses were constructed, however they had limited daylight and poor natural ventilation. [4] For my thesis, I have studied typologies of the Vietnamese infill house. The study analyzes 4 types of infill sites based on different site access. In response to the analysis, six house schemes were developed on two of the types of long and narrow infill sites, in the high-density area of Hanoi, Vietnam. The design investigates different site strategies, and applies suitable building techniques to create viable living spaces that improve natural daylight and ventilation.
