In today's world, learning is no longer confined to classrooms or defined by formal education alone, it happens everywhere, in many forms. From music halls and sensory libraries to neurodiversity training centers and public schools reimagined, the spaces that support learning are becoming just as varied as the ways we learn. This selection of unbuilt educational projects submitted by the ArchDaily community reflects that shift, exploring how architecture can embrace difference, nurture curiosity, and create environments that support a broad spectrum of cognitive, emotional, and social needs.
21st Europe, a Copenhagen-based think tank founded by former SPACE10 creative director Kaave Pour, has introduced its second major blueprint, Continent of Play. Developed in collaboration with design and architecture studioSpacon, the proposal reimagines playgrounds as vital civic infrastructure, positioning them alongside museums, transport hubs, and energy grids as defining spaces for Europe's future.
Across diverse climates and landscapes, architects are reimagining the home as a place deeply rooted in its surroundings, where architecture and environment work together to nurture well-being. This curated selection of unbuilt residences, submitted by the ArchDaily community, are conceived as sanctuaries, offering respite from the pace of urban life and drawing on the restorative qualities of greenery, water, and open air. Nature is utilized as an active presence, shaping courtyards, guiding circulation, and influencing the choice of materials and colors.
In today's architectural discourse, masterplanning is increasingly recognized as a means to reconcile growth with long-term social, cultural, and environmental priorities. Beyond organizing buildings and infrastructure, these large-scale proposals aim to regenerate urban fabrics, adapt historic or underutilized sites, and establish frameworks for inclusive and resilient communities. Submitted by the ArchDaily community, the projects featured in this edition of Unbuilt Architecture highlight how masterplans can respond to contemporary challenges while preparing cities for an uncertain future.
Spanning diverse geographies, from Europe to the Middle East and the Americas, the selected projects reinterpret industrial complexes, cultural sites, and residential neighborhoods through strategies that prioritize sustainability, mobility, and collective identity. Many share a focus on regenerative design: reopening historic canals, creating climate-adapted public spaces, and introducing green corridors and community hubs to reconnect people with their environments. Together, they showcase how masterplanning is evolving into a critical tool for rethinking how cities grow, adapt, and sustain civic life.
The summer of 2025 has brought extreme heat across Europe and beyond, with record-breaking temperatures and widespread climate-related impacts. Red alert warnings have been issued in France, Italy, and Spain as temperatures exceeded 46°C in parts of the Iberian Peninsula. These conditions have led to school closures, restrictions on outdoor work, and pressure on urban infrastructure, including power grids and public transport systems. The heatwave has simultaneously intensified wildfire risk across the Mediterranean. In western Turkey, ferocious wildfires near Izmir forced the evacuation of over 50,000 people as high winds and low humidity fueled rapidly spreading flames. In Spain's Catalonia region, two people died in a wildfire that raced across farmland and old structures in Torrefeta on July 1. Similar disasters have occurred in Greece, France, and Italy, with evacuations throughout southern Europe as widespread heat‑induced drought exacerbates fire season intensity.
Urban green spaces are considered one of the most appropriate and accessible ways to mitigate the effects of rising temperatures in urban environments. As the global climate warms, cities worldwide face more frequent and extreme heat waves, putting their citizens at risk. Many cities are employing strategies for reducing the impact of urban heat islands, which are generated when natural land cover is replaced with surfaces that absorb and retain heat, such as pavements and buildings. This raises the temperature by several degrees compared to the surroundings. Cities have their micro-climate, influenced by this phenomenon combined with a series of often overlooked factors. For a climate strategy to be efficient, all factors need to be taken into consideration.
Foster + Partners has just released the design for the redevelopment of Palas Iași, a major mixed-use development in Iași, a city in eastern Romania. The proposal includes a new masterplan centered around the historic Palace of Culture and aims to improve urban connectivity, enhance public green spaces, and upgrade the existing commercial infrastructure. Developed in collaboration with Romanian developer IULIUS, the project aims to bring together retail, cultural, and landscape elements within a unified and accessible framework.
Phase four of the King's Road Park masterplan, designed by Foster + Partners for St William, has received detailed planning permission. The design, located in the London Borough of Hammersmith & Fulham, comprises two residential towers of 28 and 38 stories, a seven-story podium building, and 1.9 acres of new parkland and public open space, totaling 357 new homes. The residential buildings incorporate communal spaces, including a ground-level amenity and a rooftop garden sheltered by a louvered canopy. The towers' slender profiles are intended to complement the existing urban skyline, featuring terracotta paneling in a nod to local architectural styles.
