As climate variability intensifies, extreme storms are becoming more frequent in some regions while water scarcity deepens in others. Architects are increasingly pressed to reconsider how buildings engage with rainfall as an environmental force and a design resource. How can architecture move beyond shedding the excess water to actively collect, store, and reuse it? What would it mean to treat rainwater as a material that shapes resilient and meaningful spaces?
As the year culminates, it's once again time for the ArchDaily team of curators to reflect on the best-performing projects of 2025 and consider what readers were most interested in. Through this diverse overview, we assess the cross-continental similarities and differences in trends and construction development. This year brought us many grand cultural and public spaces by Lina Ghotmeh, BIG, Zaha Hadid Architects, DnA, and Serie Architects, who populated events like Expo Osaka and the Venice Biennale, as well as a surprising number of museums and public or landscape works in China and the rest of the Asian continent. However, while these were sought-after projects, the leading works remained, unsurprisingly, residential projects.
More specifically, the houses that were most viewed on the ArchDaily global site were concrete houses that bore considerable injections of greenery and landscape focus. They propose layouts highlighting voids and double heights, as well as inner courtyards or large openings to the exterior. While some references did suggest traditional or vernacular elements, modernist revivals were still predominant. Material trends are much more tame, with a recurrence of raw concrete use, as wood and stone were common accent elements. Still, the more interesting thing about the works this year is the efforts brought by architects in situating and setting the projects within their surroundings, bringing special attention to landscape and how projects merged with nature.
Earth-based flooring materials comprise natural elements such as clay, sand, silt, lime, and organic fibres. They offer both structural performance and sensory engagement when used in both outdoor and interior spaces. Due to their thermal properties, durability, and sustainable qualities, these materials have evolved from vernacular construction techniques into high-value architectural elements that are always being reinvented and optimized. There are several types of earthen floorings, each offering unique benefits, and they are increasingly used in interior settings.
It shouldn't be too surprising that architectural concepts were traveling around the globe long before the online spread of information. While many regions share certain historical events and hence references (such as colonization and the mid-20th-century independence movement/ turn of political systems), others might have simply developed parallel solutions to similar climates and material availability. Additionally, it was only natural that with the dissemination of a more uniform architectural pedagogy acquired while studying abroad, followed by the internet boom, we would find almost twin projects from every corner of the world. While these might look nearly identical from some angles, they might bear different layers and stories. Then again, they might also display the same reasoning and prompts shared by counterparts from across the seas.
Student housing has undergone a remarkable transformation over the last century. Once seen as a utilitarian necessity, providing shelter and basic amenities for students, this architectural typology has evolved to address increasingly complex societal, cultural, and urban demands. Starting with Le Corbusier's modernist approach at the Cité Universitaire in Paris, student housing has reflected broader trends in architecture, urbanism, and social change.
Today, these buildings must cater to a highly diverse and transient population, navigating the pressures of affordability, density, and the evolving living standards of young adults. With rapid urbanization and increasing student mobility, universities now face the challenge of designing housing that is not only functional but also adaptable to different cultural and social contexts. This has led to more flexible, innovative solutions that promote both privacy and community living.
Sloped terrain offers a tantalizing prospect for developers. With breathtaking views over either natural or urban landscapes, often without the realistic possibility of being overlooked by future development, a parcel of land on a slope provides a high reward. However, whether it’s the extra excavation involved to cut and fill or cantilever out on a flat surface, the complications of water drainage, or the loss of light and difficulty of access at the front of the property, building on sloped terrains is not without its difficulties.
But it’s not necessarily the angle of the site that’s most at fault, it’s the shape of the building. By splitting up a multi-story structure and repositioning – possibly even disconnecting – each level, projects designed to comply with the existing topography by applying multiple ground levels can reduce the amount of excavation required. The split floor plan can also help to improve access and natural light and increase both interior and exterior space.
