Travertine —known as lapis tiburtinus by the ancient Romans— has endured for centuries as one of the most iconic materials in Italian design heritage. This limestone has left a lasting mark on architectural history, from the monuments of the Roman Empire to contemporary works like the Church of 2000 and the Ara Pacis Museum. Over time, its aesthetic has evolved alongside art and design, adapting to technical advancements while preserving its essence and relevance in modern architecture.
Reflecting on the past is often viewed as nostalgia or, from a more critical standpoint, as a sign of regression. However, looking back can offer valuable insights into a society that sometimes appears overly focused—if not obsessed—with the future and technology. In architecture, this reflection allows us to reconnect with our roots and appreciate the knowledge accumulated over generations. It invites us to explore how our ancestors designed durable structures adapted to their environment. Refined through centuries of observation, experimentation, and likely even errors, these systems demonstrate a profound understanding of local materials and building techniques.
Landscape architecture has traditionally been associated with lush greenery, rooted in the historical development of gardens and parks as spaces that bring nature into urban areas. This connection to greenery is deeply ingrained in the origins of the field, where the creation of verdant retreats was seen as both aesthetically pleasing and beneficial to human well-being. However, in regions like the Middle East, where water scarcity and harsh climates are more prevalent, there is a growing trend toward using local materials such as sand, stone, minerals, and indigenous plants. This shift reflects a more sustainable approach, reimagining landscape architecture to align with the environmental and cultural contexts of the region.
Throughout history, stone has been a vital building material because of its strength, beauty, and inherent appeal. Stone has been used to build long-lasting constructions for ages, from historic monuments to contemporary residences. Because of its resilience, it is suitable for both interior and exterior design projects, providing a diverse array of appearances. There are numerous varieties of stone, each with a distinct texture and color, including marble, granite, and limestone. Because of this diversity, stone may be creatively used by architects and builders to create accents or entire buildings. This curated selection of Unbuilt Architecture, submitted by the ArchDaily community, showcases how stone is still a dependable and adaptable building material that can combine old-world craftsmanship with contemporary style.
Thermal mass is the ability of a material to absorb, store, and release heat. Used to moderate building temperatures by reducing fluctuations, the concept is crucial in improving energy efficiency. Materials with relatively high thermal mass, such as stone, concrete, rammed earth, and brick, can absorb significant heat during the day and release it slowly when temperatures drop at night, reducing the need for heating and cooling systems. Properties like heat capacity, thermal conductivity, and density are all considered when assessing the thermal mass property of a material.
A Trombe wall is a passive solar building feature that enhances thermal efficiency. Positioned on the sun-facing side of a structure, it consists of a wall made from materials like brick, stone, or concrete, and a glass panel or polycarbonate sheet placed a few centimeters in front of it. Solar radiation penetrates the glass during daylight hours and heats the masonry wall. This wall then slowly releases the stored heat into the building during the cooler nighttime hours, maintaining a more consistent indoor temperature without the need for active heating systems.
Organizing, shaping, stacking. Transforming raw materials from the soil into architecture. This is a challenge that many Latin American architects embrace, demonstrating that scarcity can be daunting but also a rich opportunity to unleash creativity.
The use of materials extracted from the local soil serves a dual purpose. In regions with limited industrialization, using locally sourced materials makes economic sense because industrial materials such as concrete and steel are expensive and often require long-distance transportation, adding to their cost. Environmentally, choosing locally sourced materials from the start of a project reduces transportation needs and carbon emissions, supporting sustainability efforts.
“The Mindfulness City will be a sustainable city. To be mindful is to be aware — to perform best,” said Giulia Frittoli, partner and head of landscape at BIG. The Kingdom of Bhutan is a landlocked Buddhist country in the eastern Himalayas, nestled between China and India. It covers 14,000 square miles and has a population of nearly 800,000.
The Royal Office of Bhutan asked BIG, Arup, and Cistri to develop a plan for a new Mindfulness City in Gelephu in southern Bhutan, near the border with India. The city will span 386 square miles and include a new international airport, railway connections, hydroelectric dam, university, spiritual center, and public spaces.
Due to their aesthetic, sustainable, durable, and resistant qualities, stone materials have accompanied the disciplines of architecture and engineering since their origins. As is known, in Mexico, stone has been a fundamental element in pre-Hispanic constructions where experimentation was done with vaults, ashlars, masonry, etc.
However, the industrialization of this material, the perfection of techniques, and experimentation with its various applications have allowed buildings erected today to continue using it in different ways and various regions of the country, specifically in wooded areas. For this reason, we have compiled a selection of projects that include houses, haciendas, hotels, restaurants, and terraces to continue inspiring you.
From Tafí del Valle to San Carlos de Bariloche, the implementation of natural stone in contemporary Argentine architecture reveals the decisions of architects seeking to maintain a dialogue with their surrounding environment and highlight the purity of materials. While stone is one of the oldest building materials, enduring throughout history, its application in homes in Uruguay, Brazil, and Mexico highlights different characteristics in terms of textures, shapes, shades, and patterns.
Nowadays, the cycles of change around society and architecture have generated new urban models, emerging technologies, and design trends that underline the need for constant adaptability in all areas. In this context, aspects such as flexibility, reliability, and simplicity emerge as distinctive elements, both in architecture and in the components that constitute it, including materials. This is why lines such as the EGGER Decorative Collection 24+, crafted from wood-derived materials, seek to redefine concepts through a rolling series, updated at most every two years. This dynamic enables a more agile response to new trends, influences, and product innovations that arise in the built environment.
A building’s materiality is what our bodies make direct contact with; the cold metal handle, the warm wooden wall, and the hard glass window would all create an entirely different atmosphere if they were, say, a hard glass handle, a cold metal wall and a warm wooden window (which with KTH’s new translucent wood, is not as absurd as it might sound). Materiality is of just as much importance as form, function, and location—or rather, inseparable from all three.
Here we’ve compiled a selection of 16 materials that should be part of the design vocabulary of all architects, ranging from the very familiar (such as concrete and steel) to materials that may be unknown to some of our readers, as well as links to comprehensive resources to learn more about many of them.
As AI has become more accessible, we have witnessed examples illustrating its diverse applications. Prominent among these are generative AIs, which excel in their ability to “create” images through prompts, many distinguished by their composition and vividness. These AI systems are neural networks with billions of parameters, trained to create images from natural language, using a dataset of text–image pairs. Thus, although the initial question posed by Turing in the 1950s, “Can machines think?” still recurs today, the generation of images and text is grounded in existing information, limiting their capabilities.
What has surprised many is the increasingly apparent closeness to overcoming the Turing test and the growing similarity, in terms of visualizations, to what an architect with skills in this field can achieve. In this context, while the debate persists in the architectural community about whether AI can process architectural concepts, this article explores how it interprets materials to develop these visual representations. With that in mind, a single prompt was developed for this experiment (with materiality as its variable) to delve into the obtained results.
With an air of simplicity and wisdom, engineer Julio Vargas Neumann welcomes us. His two dogs accompany us as we descend after the necessary ascent to enter, and we are also accompanied by the stone walls defining the lot. We sit down and begin - or continue - the interview and conversation regarding the value of 'shicras', local materials, and earth construction. We also discuss criticisms of cement, aluminum, and steel, as well as perspectives on the future of materials in Peru and the world. Likewise, we delve into the long-neglected and recurrent rural problem in South America, discussing the inexorable need to change paradigms and priorities.
After over two decades in the making, the Perelman Performing Arts Center opened to the public on September 19, 2023. The luminous cube-shaped building was designed by the architecture firm REX, led by Joshua Ramus, to become one of New York City’s cultural keystones and the final piece in the 2023 Master Plan for the rebuilding of the 16-acre World Trade Center site. The inaugural season will feature commissions, world premieres, co-productions, and collaborative work across theater, dance, music, opera, film, and more. While only eight stories high, the venue stands out due to its monolithic façade composed of translucent veined Portuguese marble.
What does architectural restoration, transformation, or renovation entail? What factors are involved in their processes? When delving into the interiors of Spanish homes, we set out to discover the various methodologies, tools, and technical and construction strategies that are often employed, with stone as the main protagonist.
From the pre-Columbian period of the Americas –during which cultures such as the Olmec, Maya, Purepecha, and Mexica (Aztec) thrived– to the modern era where architecture has been influenced by social movements and even natural disasters, Mexican architecture showcases a valuable architectural expression, with its own unique voice and distinctive characteristics. Nobel Literature Laureate Octavio Paz argued that architecture is an incorruptible witness to history. Likewise, the materials used to shape it have acted as protagonists of that history, enduring in many cases over time and evolving thanks to the generations of architects who have contributed to it, from different perspectives.
To trace a timeline, it is possible to take as a starting point pre-Hispanic architecture, which exhibited a diversity of nuances due to Mexico's vast territorial extension. This allowed diverse cultures to find their niche and develop their characteristic architectural styles. Subsequently, the era of Spanish colonization, which itself drew influence from Islamic architecture, represented a noteworthy turning point in architectural development. This phase endured until the advent of Mexican Independence in the 19th century. In turn, this marked the initiation of social and cultural movements, both during and after the Mexican Revolution in the early 20th century.
Materiality is a determining factor in shaping the character and experience of a building. Playing with the aesthetic and tactile qualities of materials, the design process encompasses their analysis, selection, and arrangement to create purposeful and sensory-rich spaces. Alongside textures and patterns, exploring materiality also involves the study of color possibilities. The versatile role of color in architectural materials extends beyond mere aesthetics, as it can broaden design opportunities and influence emotional responses, functionality, cultural relevance, and environmental performance.
Even though each material has its distinctive inherent color, the addition of artificial or natural pigments can modify them in favor of the project’s identity. Delving into the debate on maintaining raw aesthetics or changing a material’s natural hues, we showcase various projects to study the differences between using natural versus artificial pigmentation of glass, concrete, brick, stone and wood.
