Buildner has announced the results of its competition, the Last Nuclear Bomb Memorial No.6. This competition is held each year to support the universal ban on nuclear weapons. In 2017, on the 75th anniversary of the 1945 bombings of Nagasaki and Hiroshima, which claimed the lives of over 100,000 people, the United Nations adopted the Treaty on the Prohibition of Nuclear Weapons.
High-rise architecture continues to serve as a primary tool for accommodating density in rapidly evolving urban environments. Traditionally defined by efficiency and repetition, the tower is increasingly being reexamined as a more complex spatial and organizational system. Across different geographies, architects are testing how vertical structures can move beyond singular functions to incorporate layered programs, environmental strategies, and new forms of occupation.
The following selection brings together unbuilt projects submitted by the ArchDaily community, highlighting a range of approaches to the contemporary tower. From mixed-use developments and residential high-rises to speculative ecological proposals, these works reflect an ongoing shift in how vertical architecture is conceived. These towers engage with broader questions of privacy, coexistence, adaptability, and urban integration.
Residential architecture continues to offer a productive ground for unbuilt exploration, revealing how architects respond to site, climate, and constraint at the scale of the domestic. In this Unbuilt edition, submitted by the ArchDaily community, the selected projects bring together a range of proposals that reconsider the house not as an isolated object, but as a spatial system shaped by its environment. These works position architecture as a framework that negotiates between ground, material, and inhabitation, often emerging directly from the conditions of the site.
Across varied geographies, from Kerala and Cartagena to Amman, Tromsø, and Zwolle, the projects demonstrate diverse responses to domestic architecture. They include compact urban dwellings organized through vertical layering, courtyard houses partially embedded within the ground, residences adapted to sloping terrains, and typological transformations shaped by regulatory constraints. Some projects explore linear spatial sequences rooted in traditional proportions, while others organize domestic life around atria or excavated voids that mediate light, ventilation, and privacy. Together, these proposals examine how the house can be structured through section, material, and environmental performance rather than formal expression.
