New York City is a place of constant transformation. Since the late 18th century, when it became one of the world's largest ports, it has established itself as a hub of innovation, commerce, and cultural diversity, attracting immigrants from all over. The rapid industrialization of the 19th century spurred a proliferation of factories, warehouses, and working-class neighborhoods, like Brooklyn and the Lower East Side, which shaped the city's urban and economic growth.
In densely populated cities, the demand for more living space has led to a growing trend in home extensions. With limited opportunities for new construction and a desire to preserve historical urban fabric, homeowners are increasingly looking for innovative ways to expand their homes. Home extensions offer a practical solution to modern needs, allowing residents to stay in familiar neighborhoods and maintain their ties to the community.
There are several approaches to these renovations. Home additions take various forms, ranging from isolated rooms with specific functions near the main house, to volumes directly attached to the original structure. These extensions can be built on the ground floor or take advantage of vertical space by constructing additional levels on the existing building.
Like a musical composition, there is a particular category of buildings whose history might be compared to an unfinished symphony. Alternating between high notes and moments of silence, these structures are intermittent narratives that have spanned centuries. One of the most emblematic cases is the Sagrada Familia, which has been under construction for over a century and is on track to be completed this decade. While a hundred years of construction is no small feat, another building in this group surpasses that range: the Cathedral of Málaga, located in southern Spain, has been in the making for over five centuries.
Driven by Renaissance influences, the cathedral began construction in 1528. Since then, it has experienced periods of interruption throughout its history, resulting in an unfinished landmark. The cathedral is still missing one of its towers, has incomplete elements on its facade, and its vaults are exposed to the weather due to the absence of a covering structure. Over the years, various works have been undertaken—including the recent adaptation of tourist access to the domes—but one major task remains: the gable roof. Originally proposed in 1764 by Ventura Rodríguez, its design has been reimagined and will now be executed using contemporary wooden construction techniques.
The term "retrofit," unlike rehabilitation or restoration, has been adopted by the market to address technological upgrades in existing buildings. These projects focus on aligning constructions with local technical standards and adapting spaces to be more functional and sustainable, meeting current demands.
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.
Selected by ArchDaily as one of the Best New Practices of 2024, IDK is injecting a fresh and dynamic approach to building communities with quality architecture.

The three, driven by a strong mission, to help communities and progressive institutions, organizations and cultures thrive – have been researching and delivering community-oriented projects that embody experimental building with a holistic approach. Their work focuses on nurturing social development, with an emphasis on ecological awareness, local material use, smart resource and budget management, respectful refurbishments, and designing only what is necessary without "over-building."
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.
Listed buildings are important architectural testaments to a society's rich and diverse history. Formally recognizing these buildings protects their significant architectural elements from alterations and demolitions while creating socio-economic avenues to aid their conservation. However, these buildings also run at risk of being alienated from new materials and modern building systems that allow them to function optimally today.
Integrating new materials and building services without interfering with the building’s original character is a unique design challenge. Whether adding new materials during structural renovations or integrating modern fire protection systems, there is a need for sensitivity and balance. This applies to various elements of listed buildings, including walls, floors, roofing, and façades, ensuring they are future-proofed for an extended lifespan.
Kohn Pedersen Fox (KPF) has announced an expansive project to redevelop and refurbish the Foster + Partners designed 8 Canada Square building, also known as HSBC Tower, in Canary Wharf, London. Following an international competition, the remodeling plans include removing large parts of the 42-story building to introduce terraces and additional functions. According to Canary Wharf Group and the Qatar Investment Authority, this represents the largest transformation of an office tower into a sustainable mixed-use building. The project is set to begin in 2027, after the expiry of the HSBC lease.
Throughout the history of architecture, energy efficiency, and CO2 emissions were considered marginal issues until the late 20th century. The low scores of some iconic modernist buildings in the Energy Star certification program illustrate this situation. The MetLife/PanAm Building (designed by Walter Gropius and Pietro Belluschi in 1963) received a dismal score of 39 (on a scale of 0 to 100), while the Lever House (designed by Skidmore, Owings & Merrill in 1952) scored 20. The worst performance was by Mies Van der Rohe's iconic Seagram Building, constructed in 1958, which received only 3 points. On the other hand, two revered Art Deco buildings from the 1930s, the Chrysler Building and the Empire State Building achieved scores of 84 and 80, respectively, as a result of extensive upgrades to their mechanical and insulation systems.
In 1853, at the New York World Expo, a man climbed onto a suspended platform and ordered the rope supporting it to be cut. He dropped a few inches, but the safety system activated, and the platform remained stable, to the delight of the watching crowd. At that moment, perhaps not even Elisha Graves Otis realized how his invention would permanently change the course of architecture.
With the invention of the elevator, the sky became the limit, and buildings of 7 to 10 stories began to appear. Mosette Broderick, Director of Architectural and Urban Studies at New York University, explains that the Equitable Life Assurance Building that opened in 1870 with seven stories inspired both fascination and fear.
In preparation for the city of Asturias, Spain, to become one of the hosts of the FIFA World Cup in 2030, the El Molinón stadium is proposed to undergo a major remodeling process. Home Real Sporting de Gijón, the stadium is reimagined by the architecture office Sordo Madaleno together with Orlegi Sports. The proposal aims to increase the stadium’s capacity to accommodate 9,000 additional visitors to the 33,650 fixed seats during the World Cup. It also strives to reconnect the venue to its surroundings and the city of Gijón, Asturias.
RSHP’s design proposal for the Bromley-By-Bow Gasworks regeneration project has just been approved by the London Borough of Newham’s Strategic Development Committee. The 23-acre site dates back to the 1870s, housing the largest collection of Victorian gasholders worldwide, making the project one of the largest regeneration proposals in the Lower Lea Valley in London. After three years of design development, the scheme reimagines the gas holders into a mixed-use development offering new high-quality residential architecture.
In response to the Czech Republic's soaring real estate prices, architecture firm KOGAA has transformed a former storage facility in Brno into DADA Distrikt, an affordable and diverse housing development. The project's economic approach, achieved through shared funding and direct sales, bypasses extra costs associated with developers while refurbishing a part of the city’s industrial heritage, transforming it into an active urban district. The project also features sustainability measures aimed at lowering its maintenance costs, further exemplifying the intersection of affordable housing, heritage restoration, and sustainable urban living.
The project is now part of Open House Brno, a free weekend festival held annually that allows visitors to enter and explore various locations across the city and discover their stories and architectural narratives. This year, the festival follows the curatorial concept of “Inclusion and Accessibility”, showcasing barrier-free integration of urban locations and the societal impact of buildings. A total of 58 locations will be available to visitors, exploring a variety of programs and scales demonstrating
The Santiago Bernabéu Stadium is now recognized as a symbol of Madrid, Spain. Home to the Real Madrid football team, the stadium built in 1947 occupies a key position in the city, adjacent to a major transit artery. The stadium went through several refurbishments since its inauguration, most aimed at increasing the seating capacity. A major modernization process began in 2012, following an international competition. The winning design team is L35 Architects, in collaboration with GMP and Ribas & Ribas. The refurbishment project aimed to redefine the building’s relationship with the surrounding urban spaces, to improve accessibility, and to integrate more activities, from sporting to leisure, commercial, and socio-cultural functions.
Throughout the city's history, buildings have changed their use and function, which is inevitable, as each era presents unique issues and requirements. Factors such as housing types, population density in specific areas, and the emergence of new businesses and services reshape the cityscape, often outpacing the adaptability of existing structures. Therefore, revitalizing or rehabilitating buildings is logical but also necessary to meet the demands of a changing landscape.
In April 2019, a devastating fire engulfed the 860-year-old Notre Dame Cathedral in Pars, severely damaging its wooden roof and leading to the collapse of the 19th-century spire, originally designed by Viollet-le-Duc. Immediately after, French President Emmanuel Macron promised that the iconic monument would be restored in just 5 years, an ambitious deadline. As the restoration of the roof structures nears completion, in February 2023, the scaffolding for the reconstruction of the spire has been assembled. The Spire is expected to be finished by the end of the month.
Henning Larsen has been selected as the winner of an international competition for the design of Kurfürstendamm 231, a new mixed-use urban development in western Berlin, Germany. Other finalists in the competition included Cobe, David Chipperfield, and Mäckler Architekten. The winning concept centers the neighborhood around an urban courtyard which acts as a large-scale meeting place for the local community. Nine buildings define the courtyard, including the existing Agrippina House, which is set to be rehabilitated through the project.
MVRDV has revealed its design for the extensive renovation project of the Theater Koblenz, in Germany. The project includes an interior redesign and a significant backstage element makeover. The proposal, which operates within the confines of the existing structure, balances the many requirements of the brief: history preservation is taken into account alongside essential technical improvements and roof rehabilitation. Additionally, the operations building's façade on Clemensstraße will be renovated to give this backstage entrance a contemporary, expressive appearance that emphasizes its inclusion in the theater complex, clearly separating it from the building's original guest entrance. The repair preserved a significant portion of the structure for future use and used biodegradable materials as much as feasible to reduce carbon emissions.
