Interior design has been characterized by infinite alternatives in coatings, finishes, and furniture to achieve unique and unrepeatable spaces. Designers are constantly coming up with innovative solutions and materials specifically created for a distinctive spatial perception. However, there is also a trend that seeks the warmth of the interior spaces by exposing the raw building materials as they are. The richness of materials such as wood and concrete gives that feeling of durability and low maintenance that, combined with an attention-to-detail design, makes spaces look warm yet stay true in essence. See below for 35 examples of interior spaces where concrete and wood appear in their almost purest state.
What is architecture? For some, its traditional role is to bring together imagination, technical knowledge, and problem-solving, allowing architects to design and construct while balancing ideas with the means to realize them. From the stone and wood of early buildings to the steel and concrete of the 20th century, each era demanded not only an understanding of form but also of the properties and potential of the materials in use. This grasp of materials has always been a core part of the creative process, though its scope was limited by the know-how and technologies available.
Over time, that balance has begun to shift. Architects have moved from merely using materials to actively designing them, applying scientific principles and experimenting with biological, chemical, and computational processes. This evolution has expanded the possibilities of architecture, intersecting nature, technology, and art, while pushing the role of the architect into a more experimental, science-driven dimension, where the manipulation and creation of materials becomes central to the creative act rather than merely a means to achieve forms or structures.
Surfing is, without a doubt, one of the most visually striking and fascinating sports. A fluid choreography that combines strength and delicacy, like a dance on the waves, gathers enthusiasts across the world's oceans. Yet, behind this image of freedom and connection with nature, the sport also carries contradictions. It is a symbol of outdoor life and respect for the ocean, but on the other hand, it is marked by territorial disputes over waves and by an environmental footprint that rarely receives the same attention given to its aesthetics. In times of climate crisis, this paradox becomes even more evident. Surfing depends directly on the health of marine ecosystems, the very ones most affected by pollution and global warming. This tension has been pushing a new generation of shapers, architects, and material designers to seek alternatives, from plant-based and recycled foams to the reuse of industrial waste, in order to reconnect the sport with its ecological dimension.
What if the best kind of play isn't the safest? For decades, cities have built playgrounds to be clean, colorful, and easy to supervise. Yet these spaces—designed more for adult peace of mind than for children's curiosity—often strip away what makes play truly transformative: risk, unpredictability, and self-direction. Rising safety standards, shrinking public space, and the commercialization of play equipment have only further narrowed the possibilities for children's independent exploration. From a junkyard in 1940s Copenhagen to the concrete landscapes of postwar Amsterdam, a handful of architects, planners, and activists have challenged the idea that play must be neat and controlled. Their unconventional playgrounds—made of loose parts, raw materials, and abstract forms—gave children the freedom to build, demolish, explore, and get dirty.
Concrete is anything but a consensus. Some love it, others hate it. It can feel as tough as granite or soft as velvet — all depending on whose hands are doing the shaping. Treated with engineering precision or a touch of artistic flair, concrete stops being just a material and starts acting alive. It plays with light, surprises with texture, and somehow gives form to silence. Although dense and structural, concrete can take on an almost immaterial presence: light, ethereal, and contemplative. In certain spaces, it seems to disappear, dissolving into the shadows or vibrating with the surrounding light. More than just a construction element, it becomes a language, capable of evoking emotion, spirituality, and time.
Concrete is often seen as the material of modernity, defined by its structural strength, raw finish, and unmistakable gray tone. It became the default palette of 20th-century architecture, a symbol of functionality and permanence. Yet, concrete is not bound to this chromatic identity. Its color is a byproduct of the cement, aggregates, and chemical composition used in its mix, and it can be intentionally altered through pigmentation. Among the many hues explored, red stands out — not only for its visual intensity, but for its ability to root buildings in place, evoke cultural references, and imbue architecture with a material presence that feels both elemental and expressive.
Pigmenting concrete involves the addition of mineral-based colorants — usually iron oxides — during the mixing process. Unlike paints or coatings applied to the surface, these pigments are integrated directly into the concrete mass, ensuring the color permeates the material and remains stable over time. Red pigments in particular are often derived from iron oxide (Fe₂O₃), a naturally occurring compound found in clay, hematite, and other iron-rich minerals. Their deep, earthy hue connects contemporary construction with ancient techniques — from Roman pozzolana mortars to the red earth buildings of West Africa and South America.
As climate uncertainty and ecosystem changes reshape design priorities, architecture plays an increasingly active role in these discussions, rather than merely observing. Within this perspective, the idea of making a "re" encourages a conscious step back to rethink, reconnect, and realign the relationship between buildings and their environments. This approach, central to regenerative architecture, extends beyond specific technologies or scales, encompassing everything from master plans that aim to re-naturalize cities to national pavilions that combine art and science.
What is the way forward? On the one hand, many current discussions emphasize technology; on the other, there are approaches that, rather than being in opposition, complement one another and broaden the range of possibilities, drawing on tradition, ancestral knowledge, and a profound understanding of the environment. Among these perspectives, the work of Rudolf Steiner and the anthroposophical movement, developed in the early 20th century, offers a vision and insights that connect architecture with ecological rhythms, materials, and community life.
Andanzas y visiones españolas is the book in which Miguel de Unamuno collects his experiences during excursions through Spain's cities and countryside, accompanied by friends and colleagues. More than a precise geographical description, the text consists of narratives in which each region and every feature of the territory leaves a deep imprint on his thought. The literary discourse actively weaves the diversity of setting, climate, and contextualism as foundational threads, presenting the territory not only as a physical place but also as a space for reflection and contemplation. This attentive engagement with the landscape—so diverse within Spanish architecture—also resonates in the built environment, fostering in contemporary practice a sensitive adaptation to the country's varied climatic conditions, both through design strategies and material choices.

In certain parts of the world, construction is still dominated by wet systems—concrete, masonry, and cementitious materials that are poured, cured, and fixed in place. While this has long been considered the norm in some south-east Asia countries, such as Singapore, Thailand, Malaysia, and China, in most of these regions, they typically share a common trend where labor is relatively inexpensive. This serves as one of the reasons to make concrete more easily available, as one of the typical downside of concrete is its intensive labour cost - this further differentiates concrete as a cheaper and more efficient material system to be building out of.
However, not enough considerations in the region are given to the sustainability aspect when using these wet construction materials,often overlooking the significant drawbacks of its material lifecycle and the difficulty to recycle it without downcycling - making it one of the more unsustainable materials available to be built out of.
When designing a space—whether at the scale of interiors, architecture, or infrastructure—materiality is a central concern. Beyond aesthetics, materials determine how a project functions, ages, and endures. Some architects—such as Wang Shu and Kengo Kuma—have built their practices on a deep sensitivity to the potential and limits of materials. But even in the most pragmatic sense, the question arises: What lasts? What doesn't? And how do materials change over time? Naturally, materials shape atmosphere and appearance—qualities that often matter most to clients. Yet increasingly, the discourse around materiality has shifted from structural substance to surface treatment. When did we start focusing more on "decorating" our spaces by layering one material over another, rather than relying on the inherent beauty and performance of the building fabric itself?
The desire to see the world from above transcends cultures and time — an almost instinctive impulse to seek new horizons, gain perspective, and momentarily step outside everyday life. Observation towers embody that desire: built in forests, mountains, urban parks, or coastal landscapes, they invite us to pause, look closely, and discover the surroundings in a quiet or playful way. These structures offer more than just views; they offer experiences. As we climb their steps or ramps, our bodies take part in a ritual of transition — from ground to sky.
During the Time Space Existence exhibition, organized by the European Cultural Centre in Venice, Pritzker Prize-winning architect Alejandro Aravena and his firm ELEMENTAL unveiled a full-scale prototype for a new approach in incremental housing solutions. Titled the USB Core, standing for Basic Services Unit housing prototype, this proposal aims to demonstrate how efficient construction can provide all the essential housing components in a minimal space. The prototype is also the result of a collaboration between the architecture office and concrete manufacturer and researcher Holcim, and is built out of a newly developed type of net-zero concrete mix. It also incorporates fully recycled aggregates, in alignment with circular economy principles. The collaboration aims to demonstrate a more environmentally conscious yet cost-effective way of providing essential services to at-risk communities without harming the planet.
While on site in Venice, ArchDaily's managing editor Maria-Cristina Florian had the chance to sit down with Alejandro Aravena and discuss the implications of this collaboration, the urgent need for housing, and the role of the architect as the coordinator of a process involving many actors.
What makes a building architecture? The eternal debate over what distinguishes architecture from mere utilitarian construction has often included affordable and social housing as an influential topic, sparking different points of view. This question is particularly significant in the Latin American context, where unique conditions go beyond cost concerns, whether imposed or unavoidable. Limited access to financing, the prevalence of self-construction, and the spread of informal settlements are interconnected factors shaping the built environment. These dynamics foster an aesthetic that, for some, challenges notions of good architecture, manifesting in urban landscapes where exposed materials become a defining feature.

Concrete towers dominate the skylines of Asian and African cities - looming edifices embodying development. With access to the tools and materials of industrial modernity, the Global South steps onto the world stage showcasing its bounty. Yet, at the depths of rising ambitions, the construction material speaks to colonial legacies and extractive economics that result in power imbalances in the geopolitical sphere. A climate crisis on the horizon only intensifies the complicated relationship between building materials, sustainability demands, and sovereignty of many countries.
Once seen as purely utilitarian, bare concrete blocks have increasingly become part of an architectural transformation. In regions where warm climates make insulation unnecessary, this material can be left exposed, free of cladding, finishes, or embellishment. In doing so, texture, bond, and form can define the building's character and simplify construction while creating new opportunities for expression and identity. This also creates a platform to explore the concept of material honesty. Beyond its aesthetic value, using a material "as is" can significantly reduce construction costs and minimize maintenance during the building's lifespan.
Architecture and its atmospheric qualities have long been a subject of discussion, yet reaching a consensus on the matter remains elusive. This is largely because spatial experience is deeply personal—rooted in emotions, sensory perceptions, and individual preferences that are difficult to articulate in words alone. The way one perceives, feels, and interacts with a space adds another layer of complexity, making it challenging to define and agree upon its atmospheric impact. Nevertheless, architects and designers continuously strive to shape environments that are not only functional and comfortable but also capable of evoking emotions and leaving a lasting impression on their occupants.
