UNS Designs a 10-Minute Walkable City Master Plan for Multigenerational Living in Seoul, South Korea

UNS has revealed images of SeoulOne, a master plan designed for Hyundai Development Company (HDC) in Seoul, South Korea, intended as a new model for multigenerational living. The project, already under construction on a brownfield site in the northeast of the city, reimagines an existing industrial site and railway area as a 405,000 m² car-free neighborhood for a multigenerational community. A never-sleeping, green master plan for Seoul, SeoulOne is envisioned as a mixed-use mini-city where all essential services for people of all ages are available within a 10-minute walk. The design includes 24/7 residential towers, retail spaces, offices, a hotel, sports facilities, daycare centers, senior living facilities, and a medical center, offering permanent services within walking distance. More than 30% of the site is dedicated to vegetation, including pocket parks, roof gardens, water gardens, and a forest walk, creating a year-round green village.

The Year in Review: ArchDaily’s December Editorial Focus

From the pavilions of Osaka and Venice, to the roundtables of Belém, another year comes to a close. December invites us to pause and look back at the moments that defined architecture and cities in 2025. Reflection is not only an act of memory, but of foresight — a way to understand where we've been in order to imagine where we might go next. From shifting cultural narratives to material and technological breakthroughs, this past year underscored the importance of experimentation and adaptation across the built environment.

From Tirana to Monterrey: 8 Unbuilt Housing Projects Reimagining Collective Living

Collective housing remains one of the most active areas for unbuilt architectural exploration, revealing how architects are rethinking domestic life, density, and shared living across different cultural and environmental contexts. In this curated Unbuilt edition, submitted by the ArchDaily community, the selected proposals investigate new forms of dwelling that span mobile units, vertical developments, adaptive reuse, and landscape-driven residential clusters. Rather than treating housing as a purely functional container, these projects position it as a social and spatial framework that shapes everyday life, community ties, and long-term urban resilience.

Doca Linear Park / Natureza Urbana

The regeneration of the Linear Park of Doca, located in Belém do Pará, arises as a strategic urban intervention that combines infrastructure, landscape, and memory to reconnect the city to its waters through the enhancement of public spaces. Established over the old Igarapé das Almas — now a canal about 1.2 km long in the central median of Avenida Visconde de Sousa Franco — the project recaptures the hydric identity that historically structured the Reduto basin and which, throughout the urbanization process, has been buried under fragmented and functional logics.
