Can architecture shape comfort before mechanical systems enter the equation? As buildings account for nearly 40% of global energy consumption and people spend close to 90% of their time indoors, thermal performance has become one of architecture's most urgent concerns. Yet despite often being associated with insulation values, energy ratings, or mechanical systems, thermal performance begins with spatial decisions made long before technical equipment is introduced. Orientation, airflow, daylight, and the placement of openings all influence how a building absorbs, retains, and releases heat throughout the day.
Thermal performance is not only about reducing energy demand but also about maintaining comfortable indoor conditions in response to climate. Closely tied to thermal comfort—the way occupants experience temperature, airflow, humidity, and radiant heat—it influences health, well-being, and productivity as much as it does operational efficiency. Research suggests that healthy indoor environments can improve learning ability and productivity by up to 15%, reinforcing the growing relationship among environmental performance, resilience, and space quality.

When is a form still circular or rectangular? In twentieth-century modernism, this question was largely absent. Architecture was built on clarity, reduction, and formal purity. Influenced by architects such as Le Corbusier and Ludwig Mies van der Rohe, modernist design established a visual order based on rational geometry, industrial materials, and the rejection of ornament. Circle and square, function and expression, were kept strictly apart—a logic that dictated the rigid, modular layouts of traditional bathrooms for decades.
How can the most structured elements in architecture give rise to unplanned forms of everyday life? "Spontaneous order" describes how structured systems can generate unplanned but coherent patterns of behavior. In urban discourse, it is often used to describe cities: frameworks of streets, plots, and buildings that are designed, while everyday life is not. Movement, encounters, routines, and informal uses emerge from simple spatial rules rather than explicit programming. In cities, this is visible in how sidewalks, stations, and thresholds operate. The structure is fixed, but the social order is fluid, setting conditions for behavior rather than defining it.
A similar logic can be observed in architectural micro-infrastructures such as locker systems. Like cities, lockers rely on structured frameworks that do not prescribe how life unfolds within them. A locker system is highly controlled in architectural terms: repetitive modules, strict grids, standardized dimensions, controlled access. Yet once in use, it produces spontaneous behaviors. People pause in corridors, return at irregular times, linger near locker zones, or briefly interact with others doing the same. What appears to be a strictly infrastructural storage system begins to generate informal social and spatial behavior.
Fired clay has been used in construction for over 9,000 years, evolving from vernacular craft into one of the most widely applied materials in the built environment. Its durability, water resistance, thermal performance, and adaptability have made it a staple for facades, sanitaryware, flooring, architectural surfaces, and structural systems. Today, new manufacturing technologies are extending these possibilities as architects and manufacturers confront the environmental implications of material extraction and production.
What defines the atmosphere of a home? Beyond material palettes and natural light, sound plays a defining role in how spaces are perceived and inhabited. The reverberation of footsteps across stone, the muted calm of a textile-lined room, or the way music carries through an open-plan interior all shape the sensory identity of domestic space. Architecture is experienced not only visually, but acoustically.
The concept of the "soundscape" describes this relationship between people, sound, and the built environment. In residential architecture, sound is more than background noise or technical performance; it influences privacy, concentration, rest, and emotional comfort. Geometry and materiality act as the primary acoustic conductors: while concrete, glass, and stone reflect and amplify, timber and upholstery soften and absorb. Ceiling heights, circulation paths, and room proportions further shape how sound travels and settles across a space.

Water has always occupied a unique position in architecture: elemental yet elusive, functional yet symbolic. It is both a material and a medium that shapes cities, structures rituals, and influences how space is perceived. Across cultures, water is understood not only as a source of life but as a carrier of meaning, associated with purification, renewal, and continuity. Its presence in the built environment often extends beyond utility, becoming a device through which architecture engages the senses and constructs atmosphere.

When walking into a large living space, a hotel lobby, or an open-plan workplace, the first thing that can be noticed is not what divides the space, but what holds it together. There are rarely clear boundaries, no obvious rooms, no strict partitions, yet the space still feels organized. Some areas invite a pause; others dictate movement; others foster community. The transitions are subtle, but legible.
At the same time, these interiors are expected to do more. They must accommodate constant change, withstand intensive use, and respond to environmental pressures by reducing waste, extending lifespans, and avoiding frequent replacement. The question is not only how a space looks, but how it performs over time. What is actually doing the heavy lifting?

For all the spatial experimentation of the contemporary workplace, one condition has remained largely unchanged: people are still sitting. Studies suggest that office workers spend up to 89% of their working day seated—close to 36 hours a week—despite decades of ergonomic awareness. As workplaces become more flexible, social, and design-led, this contradiction becomes harder to ignore.
The office is no longer organized around a single mode of operation, nor by a fixed spatial logic. Work has become multifunctional, shifting between collaboration and concentration, collective exchange and individual focus. In response, architecture and interior design are moving away from uniform, repetitive layouts towards environments that reflect the variability of human behavior.

What if the most advanced elements in a bathroom were the ones you could barely see? In spaces where walls, ceilings, and floors form uninterrupted surfaces, fixtures retreat, and water itself becomes the primary material shaping experience. The careful placement of fixtures in bathrooms, such as sinks, taps, showerheads, and shower drains, each asserting their presence as both an object and a function. But what happens when these elements begin to disappear?
Instead of adding mounted elements to a bathroom's design, some approaches work through subtraction. The bathroom is no longer composed of visible objects, but understood as a continuous surface. Fixtures recede into walls and ceilings, allowing water, light, and atmosphere to take precedence. What takes shape is a form of minimalism and something more: an architecture that absorbs its technical systems entirely, allowing fixtures to disappear, leaving only their effects. The experience itself becomes the protagonist, no longer mediated by visible objects, but shaped directly through water, light, and space.

In highly-curated environments such as Disneyland Paris, architecture operates under a different set of expectations. Buildings are not only required to perform, they must also communicate, often instantly. Within this context, the facade becomes a visual marker that can serve as a threshold, mediating light, air, and perception. One strategy that has gained traction in this setting is the use of semi-opaque envelope systems. Neither fully transparent nor entirely enclosed, these facade systems introduce depth and variability.

During renovation projects, replacement is often preferred over refurbishment. Used fixtures are removed, new products specified, timelines secured. Particularly in hospitality projects, where closures are costly and operations are tightly scheduled, installing new components appears to be the most reliable solution. It is faster, easier to coordinate, and aligns with established workflows. Refurbishment operates differently. It requires careful dismantling instead of disposal, evaluation instead of substitution, and trust in the quality of what is already there. It introduces complexity into a process designed for efficiency.
The recent renovation of Brenners Park-Hotel & Spa in Baden-Baden demonstrates that under the right circumstances, this additional effort can become a deliberate architectural strategy for similar projects, especially when the original materials were never intended to be temporary.
Set along the outer breakwater of Port de Cap-d'Ail, located next to Monaco, the Beach House occupies a threshold between land and sea. Surrounded by water and docked boats, the building sits in close dialogue with the harbor, exposed to the shifting light, reflections, and atmosphere of the Mediterranean. Within this setting, the house reads almost like another vessel moored along the harbor wall.
When architect Dave Rowles began work on the project, however, the residence offered little of this character internally. The former private home had been stripped back almost entirely, leaving a raw concrete shell. The renovation, therefore, began with a fundamental question: how can an interior capture the qualities of its surroundings? Rather than competing with the powerful maritime context, the design focused on creating a calm, material-driven interior that frames and amplifies the beauty and experience of the surrounding landscape crafted from oak, cedar, marble, and stainless steel details. In collaboration with barth, a company specializing in interior craftsmanship, Rowles transformed the concrete structure into a cohesive interior, where natural materials, light, and refined detailing define both the interior and exterior spaces.
Does design guide usage, or does usage guide design? Students struggle to maintain focus, employees flinch under harsh lighting, and occupants withdraw from rigid spaces, often in response to environmental conditions that only become visible once a space is occupied. Light falling across a room, the resonance of sound, the texture of surfaces, or the rhythm of circulation can support focus, calm, or inspire creativity, but each can also inadvertently heighten stress and distraction. Architects and designers are exploring and questioning: how are design decisions informed, and whose knowledge is considered essential in shaping space?
What if industrial leftovers weren't waste, but the start of architectural design? At Rieder's headquarters in Maishofen, Austria, over 1,300 cubic meters of timber, 180 ceiling elements, and hundreds of upcycled glassfiber-reinforced concrete fragments come together in a building shaped as much by reuse as by planning. The new production hall, designed by Kessler² Architecture, treats material leftovers as a design resource. Developed as part of a long-term investment in sustainable manufacturing, the timber-concrete hybrid building introduces a facade technique that inverts conventional architectural workflows: instead of designing first and producing components afterward, the building envelope is generated from the material remnants already available on site establishing a new language for industrial architecture.
The pursuit of stronger, lighter, and more durable materials has guided architecture long before polymers or carbon fibers existed. One of the earliest large-scale examples of composite materials can be found in the Great Wall of China, where stone, clay bricks, and organic fibers such as reeds and willow branches were blended to create a resilient and lasting structure. These early techniques reveal a timeless intuition: distinct materials, when combined thoughtfully, produce properties unattainable by any single element. As the construction sector faces urgent ecological pressures, this intuition is being revisited through the lens of sustainability, with architects and engineers exploring bio-based, recycled, and hybrid composites designed not only for performance but also for circularity and environmental responsibility.
The potential of existing buildings to shape cities and communities in flux through reuse and adaptation is the key focus of HouseEurope! and their activism: addressing the pressing challenge across much of Europe, where it is often easier, cheaper, and faster to demolish buildings than to renovate. For decades, construction policies, industrial practices, and market systems have favored new development, often undervaluing the cultural, social, and environmental significance of existing structures. For their work advocating systemic change in architecture, HouseEurope! received the 2025 OBEL Award under the theme "Ready Made." In a conversation with ArchDaily, collective members of HouseEurope! Alina Kolar and Olaf Grawert discussed the organization's approach to architecture, policy, and collective action.

Noor Riyadh 2025 brought large-scale light installations to public sites across the Saudi Arabian capital, temporarily transforming transit hubs, historic districts, and significant landmarks into illuminated urban environments. From November 20 to December 6, 2025, Riyadh became a citywide gallery of light, motion, and shifting perception. The festival's fifth edition featured 60 artworks by 59 artists from 24 countries, including more than 35 new commissions, responding to the theme "In the Blink of an Eye." Through light as both medium and concept, the installations reinterpreted the capital's rapidly evolving architectural landscape and reflected how perception shifts in spaces shaped by heritage and ambitious urban development.

Across recent architectural discourse, interior design has been centered on how spaces shape psychological and atmospheric experience, and on what gives interior environments their emotional resonance. Attention has shifted toward small details rather than relying primarily on form or structure. Light, for instance, is not only a technical requirement but also an architectural material in its own right. It can structure space, animate surfaces, define textures, and shape atmosphere while influencing well-being. At the same time, the characteristics between minimalism and maximalism shape how atmospheres are perceived, prompting reflection on how approaches to simplicity or exuberance might influence mood. Rather than existing as opposing aesthetics, these tendencies explore how interiors interact with mental states, reflect personal identity, and respond to the subtle shifts in the way people inhabit and experience space.
