Six Unbuilt Collective Housing Projects Explore Densification and Nature

ArchDaily has put together a collection of six innovative collective housing projects that haven't been built yet, showcasing different approaches to increasing density and how architecture interacts with nature. These initiatives come from places like Costa Rica, the U.S., Ukraine, Iran, and Uzbekistan, plus one modular design that doesn’t have a specific location. Three projects focus on making the most of urban land, one proposes a floating housing complex to address land scarcity, and two emphasize suburban living with a strong connection to nature. They tackle big issues like creating livable spaces, adapting to climate change, and balancing private and communal areas. Notably, there's LTR1, a vertical neighborhood by Carazo Arquitectura, planned for 2026. Antonia Piñeiro wrote the article, published on July 31, 2026, emphasizing the urgent global housing crisis and how innovative architecture can support personal and community development.
