One of the last large brownfields in Bratislava has been awaiting its transformation for years. Today, a new phase is beginning for the area known as "Zváračák," located on Račianska Street near the Bratislava's city center.

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.

Foster + Partners has developed a masterplan for a 38-hectare former industrial site in the heart of Constanța, a port city in Romania's Dobrogea region. The design transforms the site into a "city within a city," incorporating cultural and educational buildings, retail, entertainment, sports and leisure facilities, public parks, and botanical gardens. The project aims to reconnect the urban landscape and enhance the city's experience. The proposal is rooted in Constanța's history, from its Greek and Roman origins to its more recent industrial heritage.

Czech practices UNIT Architekti, A69 - Architekti, and British firm Marko & Placemakers propose transforming the largest brownfield site neighbouring Prague's historic city centre into a dynamic urban hub. The masterplan, selected within a 2-stage international competition comprising 57 entries, envisions "a multifunctional urban framework" that mediates the infrastructural complexity of the site, establishing a new identity for the area.

The Royal Academy of Arts in London has announced the four shortlisted proposals in their Urban Jigsaw competition, which aims to generate ideas for the renewal of Brownfield sites in London. After appraisal of many high-quality entries, four finalists have been selected to move onto the next stage of the project. See the finalist proposals after the break.

The Royal Academy of Arts in London have launched a new international ideas competition which aims "to refocus attention to the huge potential of the brownfield sites that still exist across London." 'Brownfield' sites, or those earmarked for potential building development that have had previous development on them, are plentiful in the UK capital. This competition seeks "speculative ideas [which] make the most of these missing pieces in London’s urban jigsaw."
