Chimneys are among the most quietly persistent elements in architectural history. Yet their presence persists in nearly every cultural and climatic context, serving as a technical feature and a spatial, atmospheric, and symbolic device. It populates dense city skylines and anchors rural horizons alike, its vertical silhouette as ordinary as a window or a doorframe. This apparent ordinariness is deceptive. The chimney is one of the few architectural components that links the intimate scale of interior life with the expansive forces of the environment. For architects and designers, the necessity of the chimney presents a choice: to let it recede quietly into the building's functional fabric or to amplify it as a central, expressive element that shapes a project's identity.

Riken Yamamoto, born in Beijing in 1945 and raised in Yokohama shortly after World War II, is a Japanese architect celebrated for fostering community through architecture. After founding his practice, Riken Yamamoto & Field Shop, in 1973, he became renowned for works ranging from social housing, such as Hotakubo Housing and Pangyo Housing, to civic projects like the Hiroshima Nishi Fire Station and Saitama Prefectural University, all unified by modular simplicity. Honored in March 2024 as the Pritzker Architecture Prize Laureate, he was praised by jury chair Alejandro Aravena for "blurring boundaries between public and private," fostering spontaneous social interaction, and "bringing dignity to everyday life" by enabling community to flourish through thoughtful design. In this interview with Louisiana Channel, the architect reflects on the social role of architecture, emphasizing the inseparable bond between housing and context, and the need to create spaces that foster visible, meaningful relationships.

Reform and adaptation of spaces represent a significant parcel of projects ordered to architecture firms, and reuse of preexisting structures is not newness. Functions and needs change over time, therefore adaptations are required to meet new demands. However, no matter how much the maintenance of a building is, in most cases, preferred in economic and ecological sense to its demolition and a new construction from the beginning, the logic of the reuse of a space does not usually extend to its parts that become, thus, rubble.

El Garaje by Nomos has been announced as the winner of the 2021 AR House Awards 2021. Selected from a shortlist of 15 global practices, the jury praised the project for how it "rethinks the housing typology as an element to reactivate underused spaces in cities and transform rigid and obsolete infrastructure into lively solutions". House Hamburgö by Manthey Kula and House in Kanazawa by Shota Nakanishi Architects also received highly commended recognition, along with honorable mentions to Beaconsfield house by Simon Pendal Architect, Weekend House by AREA (Architecture Research Athens), and Hlöðuberg artist studio by Studio Bua.

All human activities affect the environment. Some are less impactful, some much, much more. According to the United Nations Environment Program (UNEP), the construction sector is responsible for up to 30% of all greenhouse gas emissions. Activities such as mining, processing, transportation, industrial operations, and the combination of chemical products result in the release of gases such as CO2, CH4, N2O, O3, halocarbons, and water vapor. When these gases are released into the atmosphere, they absorb a portion of the sun's rays and redistribute them in the form of radiation in the atmosphere, warming our planet. With a rampant amount of gas released daily, this layer thickens, which causes solar radiation to enter and and stay in the planet. Today, this 'layer' has become so thick that mankind is beginning to experience severe consequence, such as desertification, ice melting, water scarcity, and the intensification of storms, hurricanes, and floods, which has modified ecosystems and reduced biodiversity.

As architects, one of our biggest concerns should be the reduction of carbon emissions from the buildings we construct. Being able to measure, quantify, and rate this quality is a good way to start.

Yuval Noah Harari points out that, around 300 thousand years ago, Homo erectus, Neanderthals, and ancestors of Homo sapiens already used fire daily. According to the author of the international bestseller “Sapiens,” fire created the first significant gap between man and other animals. "By domesticating fire, humans gained control of an obedient and potentially limitless force." Some scholars even believe that there is a direct relationship between the advent of the habit of cooking food (possibly due to the domestication of fire) and the shortening of the intestinal tract and growth of the human brain, which allowed human beings to develop and create everything we now have.

Timber trusses are wooden structural frameworks used to support roofs or other heavy structures. Fabricated from a series of triangles linked by a ridge beam and purlins, wooden trusses are structurally advantageous due to their high strength-to-weight ratios and corresponding ability to support long spans. However, these structural components can also be used for aesthetic ends, and when left exposed, can complexify, beautify, and open an interior space.

Diversifying the materials of an interior space can greatly improve its depth and visual interest. At the same time, adding partitions or other delineations of internal space can help organize flow, circulation, and visibility. Polycarbonate, a type of lightweight, durable thermoplastic, is an excellent medium for both functions.

In its raw form, polycarbonate is completely transparent, transmitting light with nearly the same efficacy as glass. However, it is also lighter and stronger than glass and tougher than other similar plastics such as acrylic, polystyrene, ABS, or nylon, making it a good choice for designers seeking durable, impact and fire resistant materials that still transmit light. Like glass, it is a natural UV filter and can be colored or tinted for translucency, yet it is also prized for its flexibility, allowing it to be shaped into any size or shape. Finally, it is easily recyclable because it liquefies rather than burning, making it at least more environmentally friendly than other thermoset plastics. For example, recycled polycarbonate can be chemically reacted with phenol in a recycling plant to produce monomers that can be turned back into plastic.
