Buildner has announced the results of its Re-Form: New Life for Old Spaces, an international ideas competition examining the adaptive reuse of small-scale existing buildings. The competition invited architects and designers to propose transformations of used, abandoned, or overlooked structures with an approximate footprint of 250 square meters, located anywhere in the world. With no fixed site or program, participants were encouraged to explore alternatives to demolition and new construction through reuse strategies grounded in contemporary social and environmental concerns.
As an open-format competition, Re-Form foregrounded sustainability, feasibility, and community impact over formal or typological constraints. Submissions ranged from precise urban insertions to more speculative rural interventions, reflecting a broad range of approaches to working with existing fabric. Many projects focused on how limited, often marginal spaces could be reactivated to support new forms of collective use while responding to material, climatic, and ecological conditions.
However, despite their enclosed design appearing to be an obstacle for new uses, recent decades have seen initiatives that embrace and repurpose these structures. These projects integrate silos into the urban environment, emphasizing their significance as part of the local collective memory.
Retrofit has become a key practice in contemporary architecture, standing out for its ability to revitalize existing buildings without the need for demolition while offering significant economic and social benefits. This approach is gaining ground in the architectural field, driven by iconic projects and public and private initiatives.
The landmark of Piraeus, located in the heart of the largest passenger port in Europe, began construction in 1972 but remained unfinished and vacant for decades. Finally completed in 2023, after an international competition, it now stands as Greece's first green and digital skyscraper. The architectural firm PILA took on the design of the facades, while the office ASPA-KST designed the commercial spaces, and the new general architectural study was entrusted to Betaplan. After over four years of renovation, Piraeus Tower officially opened its doors to tenants and visitors on June 4th with a night of celebrations, establishing itself as a bustling hub and injecting vitality into the area.
There is an increasing character of abandoned buildings in many African cities and Limbo Accra; a spatial design practice, roots itself in the experimentation of their repair, reuse, and transformation. The practice views these buildings as a unique architectural typology that includes key city landmarks, from the abandoned Independence house in Lagos to the incomplete airport tower in Accra, amongst others. They see them as major opportunities for modern public space and as symbolic sites for spatial justice. Through techniques such as photogrammetry, Limbo Accra has been creating a digital archive of these buildings and collaborating with artists and designers to propose new prospects for them. ArchDaily had the opportunity to speak with Dominique Petit-Frère, the co-founder of Limbo Accra, about the collective character of these buildings, Limbo Accra’s approach to their transformation, and navigating challenges in the adaptive reuse of these structures.
Most of us have probably imagined living in a castle at some point, whether during childhood, enchanted by fairy tales, or as adults studying European monarchies. Considering this fascination, what would you think if you had the chance to buy your castle? In mid-2014, you could make that dream a reality in Turkey for just $370,000. Each luxurious 325-square-meter castle came complete with blue turrets and spiral staircases. The only catch? Your castle would be one of 731 identical ones. But who cares about exclusivity when you have the chance to live in a Disney fairy tale?
As the demand for affordable housing grows and the availability of low-cost properties diminishes, stakeholders in housing must become more innovative in their approach to social housing development. One opportunity lies in restoring and repurposing abandoned buildings. While building new houses remains the primary strategy for Housing Authorities and Associations, rehabilitating derelict buildings can be a more economical option. This approach not only maximizes the use of dilapidating infrastructure but also provides an economic opportunity to increase affordable housing within the city. Although rehabilitating derelict residential buildings may seem like an obvious solution, it becomes even more crucial when considering abandoned commercial, institutional, or historical buildings for social housing.
The relocation of a capital city is a complex urban decision with various dimensions and consequences for both the old and new capital. It can be driven by political, economic, societal, and other factors, and has urban and architectural implications for residents. These include factors such as location, planning, building design, the purpose of the old capital, climatic conditions, and separating the political/administrative hubs from cultural and economic cities.
In light of the ongoing urban discourse, countries like Egypt are constructing a new capital city to alleviate population and urban stress on Cairo. Similarly, Indonesia is planning a new capital in response to challenges faced by Jakarta, such as pollution, traffic congestion, and rising sea levels. It is valuable to examine other countries in the global south that have relocated their capital cities, noting the architectural and urban lessons learned from their experiences.
During their visit to the 18th International Architecture Exhibition in Venice, ArchDaily had the opportunity to engage in a conversation with Sevince Bayrak and Oral Göktaş, founders of the Istanbul-based studio SO? Architecture and Ideas, curators for the Pavilion of Türkiye. Their exhibition, titled Ghost Stories: Carrier Bag Theory of Architecture, explores the status and hidden potential of abandoned buildings across Türkiye to discover more hopeful proposals for the future. The conversations opened with an exploration of the status of these forgotten structures and their hidden potential, leading into the intentions behind the exhibition in Venice and the curator’s message for the wider audience.
For the 18th International Architecture Exhibition of La Biennale di Venezia, the Bulgarian Pavilion will present the exhibition titled “Education is the movement from darkness to light.” Curators Boris Tikvarski, Bojidara Valkova, and Mariya Gyaurova, joined by Belgian photographer Alexander Dumarey, have chosen to focus the exhibition on the subject of depopulation, urban decline, and rural flight, expressed through the image of abandoned schools present in the country. The project was selected following a national competition organized by The Ministry of Culture, The Chamber of Architects in Bulgaria, and the Union of Architects.
In a new show at Kunst Haus Wien in Vienna, the Austrian artist continues his investigation of architecture where few civilians tread.
Gregor Sailer’s quest for unusual structures and buildings takes him to some of the most extreme reaches of human civilization — from military field exercise centers in the USA and Europe to a mining center near Chuquicamata in the Atacama Desert to Arctic snow fields.
During his explorations of abandoned places across Europe, award-winning French photographer Romain Veillon has stumbled upon enchanting architectures that have been left to decay for decades. In his latest book Green Urbex: The World Without Us, Veillon explored what the world would look like if the human race disappeared and nature took its course without any human interference.
A building stands out along the maritime walkway in Palma, Mallorca's capital. Designed by José Ferragut Pou and completed in 1960, the building was a poster child for the modern architectural movement sweeping the globe at that time. Today, like many of its brethren, it stands in abandoned disrepair.
Lluís Bort is the Spanish architect and photographer behind "Empty Architecture," a photographic compilation of abandoned buildings from throughout the island of Mallorca, Spain.
“Abandonment Copies” is a research project created between 2016 and 2018 by artist Sandra Calvo consisting of a film, archives, drawings, interviews, and a video display which was exhibited in the Mexican pavilion during the 2021 Biennial of Venice. The project highlights architecture as a reflection of the migration process between Mexico and the United States, comparing and contrasting the houses where migrants work in the US and the ones they build in Mexico with the remittances they send.
