As one walks along the beachfront of Barcelona, the shoreline feels like it has always been there: sand, palm trees, a long promenade, restaurants, shops and modern hotels, when the reality is that it has not always been this way. Until the 1980s, Barcelona's seafront was a working barrier of railway lines, factories and informal housing, and wastewater ran straight into the Mediterranean. Starting in 1987, Barcelona has continuously created large promenades and passages between the city and the sea, creating an environment that today many might read as previously empty space, but is actually the result of decades of infrastructure and social complexity, along with a municipal effort to transform the city's territory and its relationship to the water. Following that transformation raises three questions that frame this article: who was displaced to open the waterfront, who governs it today, and who keeps it standing?

The buildings and construction sector accounts for around 39% of global CO₂ emissions and nearly 50 per cent of global material extraction. Operational carbon emissions which are associated with the energy consumed to run the buildings also rose by 1% to 9.9 billion tonnes of CO₂ in 2024, even as building energy use intensity (EUI) has improved. These figures point to persistent gaps in the way buildings are designed, constructed and upgraded. One important area for closing those gaps is the building envelope insulation, which remains central to controlling energy demand, improving thermal resilience and reducing carbon emissions.

The RIBA Stirling Prize 2026 has been awarded to Lion Green Road, a housing development in Coulsdon, South London, designed by Mary Duggan Architects with RUFFARCHITECTS for Croydon Council. Comprising 157 homes across five residential blocks, the project combines privately owned and socially rented housing on a former car park. Presented annually by the Royal Institute of British Architects (RIBA), the Stirling Prize recognizes a building considered to make a significant contribution to the evolution of architecture and the built environment. The 2026 winner was announced at a ceremony at Old Billingsgate in London on October 15, marking the prize's 30th anniversary.

The World Monuments Fund (WMF), an independent nonprofit organization dedicated to the preservation of historic architecture and cultural heritage since 1965, receives nominations through the World Monuments Watch, a flagship advocacy and conservation program. Every two years, the Watch selects 25 sites from the nominations received from individuals and community-based organizations worldwide. Nominations for the 2027 World Monuments Watch closed on March 20, 2026, with a total of 372 public nominations from 84 countries and territories. Before announcing the selected sites in early 2027, the WMF offers an analysis of the nominations. Global data shows three main causes of heritage endangerment worldwide: government austerity, intensifying climate impact, and lack of access to specialized skills and expertise. At a time when political priorities tend to stray from history, the call is to recognize heritage sites as an area of shared opportunity rather than a burden.

What do architects do? This age-old question reveals the perennial dichotomy between two aspects of building–how to construct, and why to build. Despite its ancient origins and its name deriving from Ancient Greek, the profession is one that has transformed over the centuries. Its present-day form, usually dated to the Italian Renaissance, makes a distinction between the act of building and the intellectual and aesthetic decision-making behind it. However, we may be in the midst of another nascent transformation. The commissioning of architecture has historically remained separate from the practice, but as can be seen in the work of MASS and projects like the Moving Windmills Innovation Center, this distinction is beginning to blur.

Where rivers, reservoirs, and rainfall can no longer be relied upon consistently, water is increasingly being sought in the atmosphere. Fog, atmospheric humidity, and condensation each offer different ways of collecting it. When architecture begins to collect water from the air, surfaces, structures, and open spaces become part of the water system.

According to UNICEF, Jordan's National Water Strategy estimates that each person has access to only about 61 cubic meters of renewable water per year, far below the 500 cubic meters commonly used as a threshold for absolute water scarcity. Around half of the population receives piped water only once a week, while groundwater is being extracted faster than many aquifers can naturally recharge.
