To fully know a city's architectural heritage, one must look beyond its designated sites and iconic buildings. For many, understanding a city's urban fabric and what makes it tick also means discovering the smaller-scale, locally appreciated, conserved buildings and popular gathering spaces. This is especially true when considering bustling Vietnamese cities, with their peculiar architectural characteristics, which can only be appreciated when learning about their many inspirations and historic layers, combining traditional Vietnamese motifs, modernism, local materiality, and climatic design solutions, but mostly by learning about the site constraints that are addressed through the implementation of the narrow tube houses and low-rise buildings.
