In Vietnam, the tube house has almost become a vernacular form in densely populated cities like Hanoi and Ho Chi Minh City. This typology originated from ancient façade taxes and as a strategic response to urban land scarcity and optimization of street frontage for commerce. Their traditional structure typically relies on the front façade for daylight and ventilation. People living there often face the challenge of designing in a space defined by the deep plots, limited street frontage, and close neighboring buildings, restricting natural light and airflow. To counter this fundamental lack of perimeter exposure, Vietnamese architects usually employ several strategies oriented towards internal environmental manipulation. This curated collection explores tube houses under 100 m2, where their small size increased the need for absolute spatial economy and the verticalization of function, which directly influenced design decisions across all projects.
It's no exaggeration to say that Renzo Piano is one of the most unanimously respected architects in the world of architecture. With an oeuvre that blends respect for context, lightness and technology to create environmentally conscious and aesthetically pleasing structures, his approach combines advanced materials with traditional techniques. In projects of various scales, the Genoese architect maintains an essential thread: the implementation of passive architectural strategies, highlighting the importance of these methods for sustainability and energy efficiency. This is often made explicit in his sketches, as an initial concern, and clearly comes through in the finished works. Here are some examples of iconic projects developed by his office in recent decades.
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.
The main role of architecture is to create structures that protect us from the environment and create spaces that are safe and comfortable for all types of needs and activities. By providing shelter, architecture also shapes the way people interact with their surroundings. Building technologies of the past rarely managed, however, to create a complete separation between us and the outside world.
While impermeability was a desired outcome, the porous building materials available always allowed some water, wind, or outside particles to leak into the interior spaces. In contrast, modern technologies now allow for almost completely impermeable building envelopes, allowing for complete separation between indoors and outdoors, thus relying on engineered systems to regulate temperature, airflow, or humidity. This article explores the differences between these two contrasting approaches, exploring how building facades are equipped to regulate indoor comfort and its environmental impact.

Understanding the temperature gradient in a building is essential in cold or temperate climates, where airtight enclosures and continuous insulation are used to prevent heat loss. However, this approach is not suitable for tropical areas like Central America, where the climate is marked by a consistent alternation between wet and dry seasons rather than four distinct ones. Factors such as proximity to the sea, elevation, and local topography influence microclimates across short distances, but high humidity remains a common challenge. Sealed, airtight walls with no ventilation can quickly become breeding grounds for mold, making the thermal strategies of temperate climates problematic. In response, local designers have developed alternative approaches that embrace, rather than resist, the outdoor environment, allowing airflow and evaporation to manage interior comfort.
The intersection of architecture and medicine profoundly shaped modernist design, where transparency, light, and air became essential tools in the pursuit of health. Emerging from the tuberculosis crisis of the late 19th and early 20th centuries, the sanatorium evolved beyond a medical facility into a testing ground for architectural innovation. The necessity of fresh air, sunlight, and sterility transformed these spaces into prototypes for modernist principles, influencing spatial organization, material choices, and design philosophies that extended far beyond healthcare.
More than sites of treatment, sanatoriums embodied contemporary medical theories in built form. At a time when tuberculosis — often called the white plague — devastated populations worldwide, medical professionals prescribed environmental exposure as the primary therapy. Architecture adapted accordingly, producing buildings with expansive terraces, large windows, and streamlined interiors designed to optimize ventilation and maximize natural light.
Humid environments present some of the most complex challenges in architectural design. From the tropical monsoon season of Southeast Asia to the equatorial heat of Central Africa, these environments demand solutions that account for intense moisture, high temperatures, and the constant battle against mold, decay, and stagnation. Yet, for centuries, communities in these regions have developed architectural techniques that do not fight against humidity but instead work with it, leveraging local materials, climate-responsive design, and passive cooling techniques to create sustainable and livable spaces. By considering atmosphere as a sensory and climatic phenomenon, architects will craft spaces that are not only evocative but also responsive, adaptive, and sustainable.
In recent years, working from home has become increasingly common, creating a need for domestic spaces that accommodate both professional and personal life. This is especially true for artists, where the integration of living and working spaces is essential. Often, these spaces must also serve as areas for exhibiting artistic production, such as paintings, sculptures, ceramics, and more.
This fusion of work and living environments has influenced architectural and interior design trends, prioritizing flexibility, multifunctionality, and aesthetics that foster both creativity and comfort. Open-plan layouts, modular furniture, and adaptable lighting solutions are now key elements in designs that support the seamless coexistence of work and personal life.
Courtyards have long been a fundamental aspect of traditional Chinese architecture, serving as central spaces around which domestic life is organized. These spaces play a vital role in creating a harmonious living environment, offering benefits that range from regulating indoor temperatures to enhancing social interactions and fostering a close connection with nature.
There are many advantages to incorporating interior courtyards in residential projects, both in urban contexts and in more natural surroundings. In both cases, they are a key element in improving the quality of the home's interior space in various ways. Whether in the form of a central cloister, side courtyards, or through perforated slabs and the addition of skylights, these spaces play a vital role in creating a harmonious living environment, offering benefits ranging from the regulation of interior temperature to enhancing social interactions and fostering a close connection with nature.
Beach houses along the Caribbean coast perfectly blend comfort, nature, and tranquility. With landscapes of white sands and crystal-clear waters, the Caribbean is home to some of the world’s most enchanting seaside retreats. Whether situated on popular islands like the Dominican Republic and Cozumel in Mexico or secluded spots like the untouched beaches of Costa Rica, these homes are designed to fully immerse guests in the lush natural surroundings, providing a uniquely serene experience.
Water and daylight? At first glance, they seem like distant concepts: one is tangible, while the other, —though intangible—, manifests itself through its effects and perceptible qualities. Both are powerful and recurring resources in architectural design, often employed only for compositional purposes. However, in the context of indoor pools, this combination is frequently functionally oriented, prioritizing 'protection' from external stimuli. This one-dimensional approach can restrict the dynamic interaction between water and natural light, leading to aesthetic, functional, and operational challenges.

Polycarbonate, commonly used in roofing and industrial cladding, has gone beyond its initial applications to become a material widely used across various architectural typologies. Its combination of strength, lightness, easy installation, and ability to allow natural light to pass through has made it an attractive option for residential,educational, and even cultural architecture projects. In homes, polycarbonate not only helps create bright and comfortable environments but also allows for creative use of translucency to generate private spaces without sacrificing visual connection to the outdoors.
Snøhetta has announced a project to rebuild the Refuge de Barroude, a mountain refuge located in a UNESCO World Heritage site in the Pyrenees Mountain range of France. The old building, destroyed in an accidental fire ten years ago, is set to be revived as a stop-off point for hikers on the Haute Route des Pyrénées and as a support center for the staff of the National Park. The next phase of the project is due to begin in 2025.
As the architecture industry shifts its focus towards greater sustainability and energy efficiency, many modern projects in the world’s hottest (and getting hotter) environments are unearthing more traditional ways to control temperature, light, and ventilation by learning from the past to save us from the future.
As the temperature drops in the Northern Hemisphere, cold outdoor spaces are overcome with frost, ice, and snow, and we find ourselves rushing from one heated indoor environment to the next, less willing or less able to stop and appreciate the natural world around us.
Apart from dragging a spruce or fir tree inside and dressing it up in yuletide costume, we tend to leave the real natural world to its own seasonal devices until it reemerges in Spring. However, by inviting the positive effects of plant life into our homes, we can improve both our mental health and the air we breathe by filling them with peace and joy all year round, not just at Christmas.
Not nearly as complex an architectural typology as the word suggests, a ‘clerestory’ is a simple – if lexically loose – a portmanteau of ‘clear’ and ‘story’. Denoting a section of the wall that contains windows or cavities above eye level. The word is often assumed to have a religious context. Clerestories historically appeared at the upper levels of Roman churches, Hebrew temples, and early Christian architecture after all. And the earliest references we have to the feature come from religious texts.
Today, religious structures are often typified by the light their high windows allow to stream in, both figuratively and literally, from a higher source. At the CES Chapel in Taiwan, for example, ‘light diffuses through the glass clerestory and brightens the apse throughout the day,’ explains JJP Architects & Planners, about an interior design concept driven by natural lighting, ‘the chapel is filled with a spiritual aura, with a bright cross projected deep into the space.’
Walking down the streets of cities like Hanoi and Saigon in Vietnam, you might encounter houses with surprisingly narrow facades in contrast to the stacking of three to five floors, with windows for ventilation and natural light only on the front facade. These are the famous traditional Tube Houses. According to ancient popular culture, this type of housing emerged due to property taxes being based on the width of the facade, but the true reason is to optimize land use, allowing a larger number of plots in the same square.
However, this legacy is now being recreated in contemporary designs by Vietnamese architects. Old facades give way to innovative solutions featuring atriums for natural lighting and ventilation, courtyards and interior gardens, greenery incorporated into different environments, split-levels, etc., allowing for high-quality spaces. With that in mind, we have put together a selection of Tube Houses, together with their respective section drawings. Check out below:
