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.





Renzo Piano Building Workshop (RPBW), in collaboration with Sydney and Hanoi-based PTW Architects, has begun construction of the Isola della Musica, a new opera house and convention center in Hanoi, Vietnam. Commissioned by Sun Group, the project was first conceived in 2017 and forms part of a broader masterplan that reshapes the existing boundary between West Lake and Đầm Trị Lake. Inspired by the region's history of pearl cultivation, the building features a series of curved concrete shells whose forms and surfaces evoke the texture and luminosity of mother-of-pearl.
