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.
These key styles and architectural movements are often maintained and even highlighted, as architects give a second life to many rundown or abandoned buildings, transforming them into popular coffee joints. They are reviving smaller heritage sites by pushing for their restoration and regular use by the community, encouraging visitors to acknowledge the historic relevance of the space, as they covet it.


Educational architecture remains an exploratory ground for unbuilt exploration, offering insight into how learning environments can evolve alongside changing social, ecological, and pedagogical values. In this Unbuilt edition, submitted by the ArchDaily community, the selected projects bring together a range of proposals that examine schools, libraries, nurseries, and academic centers as spatial frameworks for care, knowledge, and collective growth. Rather than treating education as a fixed program housed within singular buildings, these projects approach learning spaces as adaptive environments shaped by landscape, climate, and human interaction.
Across varied geographies, from Mediterranean hillsides and Central European courtyards to tropical cities and distributed campus models, the proposals explore diverse architectural responses to contemporary education. They range from child-scaled kindergartens organized around trees and cloisters to libraries conceived as civic landscapes, biodiversity-centered academic buildings, and schools imagined as walkable urban systems.





In Vietnam, the tube house has almost become a vernacular form in densely populated cities like Hanoi and Ho Chi Minh City. This typology originated from ancient façade taxes and as a strategic response to urban land scarcity and optimization of street frontage for commerce. Their traditional structure typically relies on the front façade for daylight and ventilation. People living there often face the challenge of designing in a space defined by the deep plots, limited street frontage, and close neighboring buildings, restricting natural light and airflow. To counter this fundamental lack of perimeter exposure, Vietnamese architects usually employ several strategies oriented towards internal environmental manipulation. This curated collection explores tube houses under 100 m2, where their small size increased the need for absolute spatial economy and the verticalization of function, which directly influenced design decisions across all projects.
