A team led by French architecture practice Coldefy, comprising CITYFÖRSTER, Sporaarchitects, TREIBHAUS.LAND, and Marko & Placemakers, has won the competition to design a masterplan for Rákosrendező in Budapest. The project is developed for the Budapest Capital Asset Management Centre, acting on behalf of the Municipality of Budapest. The design outlines a 15-year scheme to transform a brownfield site long regarded as the city's "rust belt," located on the eastern side of the Hungarian capital. The regeneration plan includes over 10,000 apartments, new transportation links, and commercial and civic spaces, forming a comprehensive urban redevelopment strategy aligned with 15-minute city principles.
Abuja was named the capital city of Nigeria on December 12, 1991. Located in the central Federal Capital Territory (FCT), it replaced the most populous coastal city of Lagos in a process of structural reform aimed at national integration and more balanced regional development. Like other capital relocations, Nigeria's capital was moved for strategic reasons to transform Abuja into the country's new administrative center, often referred to as "the center of unity." It was envisioned as a planned city based on a master plan developed by the United States-based consortium International Planning Associates (IPA). More than three decades later, a new master plan titled "City Walk" has been developed by MAG International Links Limited and designed by Benoy as a mixed-use district integrating hotels, offices, residential, retail, cultural, educational, and healthcare facilities, alongside a 450-meter tower and a 13,000-seat indoor arena across 250 hectares.
On March 5, 2026, Skidmore, Owings & Merrill (SOM) revealed images of a new landmark project in Kazakhstan, in Central Asia. The project consists of two towers, the "Iconic Complex," and a master plan for the area, the "Gateway District." The complex is located in Alatau, a new city along the Almaty–Qonaev highway planned to become an international investment hub. A strategic project for the country, the city's master plan extends through 2050, with the first phase of major infrastructure projects scheduled for completion by 2030. Within this context, SOM's design is expected to serve as the city's economic and administrative nucleus, establishing the central business district of Alatau City and setting a benchmark for future investment projects in the area.
Battersea Power Station is a former coal-fired power station located on the south bank of the River Thames in London, originally designed by architects J. Theo Halliday and Giles Gilbert Scott. Notable for its appearance on the cover of Pink Floyd's 1977 studio album Animals and in Alfred Hitchcock's 1936 film Sabotage, the station is one of the world's largest brick buildings and is known for its Art Deco interior fittings and décor. Recognized today as part of modern industrial heritage, the site's transformation into a commercial development began in 2012, with the adaptive reuse guided by a masterplan designed by Rafael Viñoly. On February 16, Battersea Power Station announced the appointment of the strategic urban design practice Studio Egret West to evolve the original masterplan for the remaining 16 acres of the 42-acre riverside neighbourhood in the southwest London.
Urban masterplans remain an exploratory ground for unbuilt speculation, offering insight into how cities might recalibrate mobility, ecology, and collective life in response to accelerating environmental and social pressures. In this Unbuilt edition, submitted by the ArchDaily community, the selected projects bring together a range of large-scale proposals that examine urban centers, waterfront districts, infrastructural corridors, and cultural landscapes as spatial frameworks for reconnection and resilience. Rather than treating the masterplan as a rigid blueprint, these projects approach urbanism as an adaptive system shaped by climate, topography, infrastructure, and public space.
Across varied geographies, from Northern European town centers and Mediterranean coastal districts to Central Asian polycentric hubs and Gulf megacities, the proposals explore diverse architectural and urban strategies. They range from park-led civic transformations built over highway tunnels to elevated pedestrian networks above active transport systems, mixed-use blocks structured by historic planning logics, marina developments integrating environmental stewardship, and research-driven models for equitable landscape urbanization.
Foster + Partners, in collaboration with Angola's Ministry of Transport, has unveiled the master plan for the Icolo e Bengo Aerotropolis, a large-scale development planned around the recently completed Dr. Antonio Agostinho Neto International Airport. The proposal organizes business, research, residential, and hospitality programs within a landscape-led framework structured around the airport. Development is planned to proceed in phases, beginning with the business and cultural district located to the north of the site.
Malabo served as the capital city of Equatorial Guinea from the country's independence from Spain on October 12, 1968, until January 2, 2026, when a decree issued by President Teodoro Obiang Nguema Mbasogo officially transferred the capital to Ciudad de la Paz ("City of Peace"), located in Djibloho Province. Obiang formalized the move as part of a long-planned territorial reorganization. While the former capital remains an important economic center on Bioko Island, Ciudad de la Paz was conceived as a planned capital on Africa's mainland. The initiative to relocate the capital dates back to 2008, with construction beginning in 2011. The new capital, also referred to as Djibloho, after the province, or Oyala, has been framed by the government as a decentralization effort aimed at improving national accessibility.

During 2025, several sports infrastructure projects were announced that remain on our radar, most of which are scheduled for completion between 2028 and 2030. Located across Asia, Europe, Africa, the Middle East, and North America, these projects reflect contemporary masterplan strategies for the transformation of large sports venues within their urban contexts. Many of the stadiums are planned as part of broader redevelopment frameworks that include new public spaces, mixed-use programs, event facilities, and mobility upgrades, rather than as isolated structures. Designs led by international offices such as Populous, Foster + Partners, Heatherwick Studio, OMA, Gensler, AFL Architects, and VUILD illustrate a range of architectural, urban, and infrastructural responses to the evolving role of large sports facilities.
Construction has officially broken ground on Tokyo's new global headquarters for NTT, a major Japanese technology company.

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.
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.
Across varied geographies, from Tirana and Athens to Monterrey, Chaloos, Roatán, Bhola, and the DRC, these proposals explore multiple approaches to collective living: transforming industrial shells into residential structures, extending existing masterplans through landscape integration, reimagining verticality in dense urban centers, and developing modular prototypes that can adapt to changing climates or patterns of mobility. Some projects prioritize ecological strategies and local materials, while others test new models for accessibility, community well-being, or incremental urban growth. Together, they reflect a broad spectrum of architectural responses to contemporary housing pressures.
RSHP has announced the completion of the Barangaroo South Masterplan in Sydney, marking the realization of a 15-year redevelopment that has reconnected the city's north-western harbour edge to its urban core. Once a disused container port, the 22-hectare site has been transformed into a mixed-use, carbon-neutral precinct, integrating commercial, residential, and public spaces along the waterfront. Developed in collaboration with Lendlease following an internationaldesign competition, the masterplan is organized into three zones: Barangaroo South, a high-density extension of the Central Business District; Barangaroo Reserve, a reconstructed natural headland that reintroduces native landscapes to the harbour; and Barangaroo Central, a low-density residential area linking the northern and southern ends of the development.
As cities and landscapes evolve, architecture is increasingly asked to support well-being,performance, and collective experience. From stadiums that honor deep cultural memory to intimate wellness spaces that foster restoration and connection, sports and wellness typologies are expanding beyond mere functionality. They create environments where movement and health intersect with design quality, sustainability, and social meaning. Today, these spaces range from elite training grounds and recreational clubs to contemplative retreats and inclusive public amenities, shaping how communities gather, heal, and celebrate shared identity.
This selection of unbuilt proposals submitted by the ArchDaily community illustrates that diversity. In São Paulo, Luiz Volpato Arquitetura reinvents the historic Santos Futebol Clube stadium with a geometry that preserves fans' memory while introducing new commercial and social uses. In Hanoi, Van Aelst I Nguyen and Partners bring filtered light and fresh air to a dense urban sports complex. In Dubai, RSP proposes Haven, a residential development anchored in holistic wellness and nature-driven experiences, while India's Tropic Responses imagines Aira Club as a climate-conscious leisure hub. High in the Himalayas, Gadasu + Partners carve a meditative spa into mountain stone, and in Isfahan, Arsh4d Studio rethinks segregated women's parks to create inclusive, future-oriented civic space.
