Green Roofs: The Latest Architecture and News

On February 20, Renzo Piano Building Workshop announced that the building permit for the Hôpital Universitaire Saint-Ouen Grand Paris Nord (HUSOGPN) has been officially granted. The project is a state initiative responding to rapid population growth, increasing demand for care, and evolving technical standards with a "next-generation" hospital in Saint-Ouen-sur-Seine, a commune in the northern suburbs of the French capital. The hospital will be located on the site of the former PSA factory, once an industrial engine of the region and now large and well-connected enough to host a program of rare scale: 986 beds and 288 day places, a workforce of over 5,500 professionals, and facilities equipped with contemporary technology for areas such as surgery and maternity. Envisioned as a "hospital-landscape," the building designed by RPBW in association with Brunet Saunier & Associés stands out for featuring a 1.3-hectare roof garden and an urban forest with over 1,000 trees.

Cities bring together the best and worst of the human condition. They concentrate opportunities for work, social networks, and cultural production, but they also expose deep social inequalities. Among the many forms of urban exclusion are limited access to transportation, housing, leisure, or safety issues. One form that is rarely discussed is thermal inequality. In lower-income neighborhoods, where there are fewer trees, parks, and permeable surfaces, heat accumulates and thermal discomfort dominates, resulting in higher energy consumption and health risks. As concern about the climate crisis grows, this discussion becomes more urgent: extreme heat is no longer just a climatic phenomenon but also a spatial expression of inequality.

Extreme heat is one of climate change's most urgent and rapidly growing consequences, especially in cities. Urban areas are particularly vulnerable because they trap heat in building materials and urban streets, creating dangerous conditions for residents. As temperatures continue to rise and heat waves lengthen, cities are grappling with how to remain livable in the face of this intensifying threat.

Urban living has become synonymous with limited space and creativity for compact apartments. As cities become more dominated by concrete and steel, there is an exciting, yet unsurprising, rise in interest in embracing the green thumb, even within the constraints of a dense urban environment. This interest is not purely to tend aesthetic tastes, as studies consistently show that exposure to nature reduces stress, improves focus, and enhances overall well-being. However, in dense urban environments, the challenge lies in finding innovative ways to make this vision a reality for apartments where every inch matters.

As record-breaking temperatures sweep across European cities, practitioners have recognized that existing infrastructure is poorly equipped to address the impacts of climate change. In response to this concern Roofscapes, a startup emerging from the MIT School of Architecture and Planning, has developed innovative solutions to amplify urban climate resilience. Their approach focuses on the strategic adaptation of underutilized spaces such as rooftops. By tackling the immediate challenges posed by extreme heat, the startup's work epitomizes how architectural innovation can directly contribute to addressing climate adaptation needs in cities. The company was recognized as one of ArchDaily's 2024 Best New Practices for their innovative approach to tackling urban issues such as affordability, lack of biodiversity, rising urban temperatures and repurposing.

Dating from the1940s, the air raid shelter in Hamburg’s St. Pauli district has been reimagined as a „green mountain,” with expansive gardens covering the top of the wartime structure. Known as the Hochbunker, translated as ‘high bunker,’ the location has undergone a substantial restoration and refurbishment process introducing restaurants, event spaces, and a hotel, together with a rooftop urban park. The bunker has opened to the public on July 5, 2025, with the purpose of reconnecting the community with the iconic structure and its complex history.

Stefano Boeri Architetti has been declared the winner of the international competition for the redevelopment of a former industrial site in downtown Bratislava. The project includes the transformation of one of the largest abandoned areas in the Slovak capital, with the aim of creating an active new central hub for the city, complete with parks and public spaces, residential units, and a variety of amenities. Stefano Boeri Architetti’s master plan proposal, titled “Urban Oasis,” has been appreciated by the jury for integrating familiar typologies, creating a “European matrix” of medium-density developments organized around accessible public spaces.

Foster + Partners, led by Norman Foster, has just released the designs for a new office tower in New York, United States. Spanning 139,354 square meters, “350 Park Avenue” will be the office space for Citadel Securities, committing to at least 78,967 square meters of the overall space. Seeking to rejuvenate the iconic street, the all-electric tower will integrate into the urban fabric of New York, standing alongside architectural landmarks in Midtown Manhattan.

MVRDV has just begun construction on the LXK Office and Residential Campus in Berlin. Situated in Friedrichshain, near Berlin Ostbahnhof, the development spans approximately 61,200 sqm and boasts city center views from its green rooftops and terraces. Designed as two buildings, a horizontal band encircles the middle of either structure, serving as a distinctive landmark in Berlin.

Architecture in Mexico has a vast history that is made up of various aspects that touch astrological, political, spiritual and economic issues. Although today there are only ruins of some of the most important pre-Hispanic complexes, thanks to the in-depth research that has been carried out, we can have some representations of what those buildings that laid the foundations of what makes us today were like. In these representations, it is possible to notice the presence of natural materials that were a response to their environment such as basalt stone, stucco and some vegetable paintings whose remains persist to this day.
