Experimenting with a very rigid material, Antony Gibbon imagines a residential project where the outer concrete shell twists and turns, in order to create livable spaces. With a very basic function, the proposal is an invitation to push technical boundaries and unleash the imagination.
With the intention of maximizing available space and avoiding steep construction costs, researchers from ETH Zurich’s Department of Architecture have devised a concrete floor slab that with a thickness of a mere 2cm, remains load bearing and simultaneously sustainable. Inspired by the construction of Catalan vaults, this new floor system swaps reinforced steel bars for narrow vertical ribs, thus significantly reducing the weight of construction and ensuring stability to counter uneven distributions on its surface.
As opposed to traditional concrete floors that are evidently flat, these slabs are designed to arch to support major loads, reminiscent of the vaulted ceilings found in Gothic cathedrals. Without the need for steel reinforcing and with less concrete, the production of CO2 is minimized and the resulting 2cm floors are 70% lighter than their typical concrete counterparts.
Air-conditioning isn’t just expensive; it’s also terrible for the environment. Accounting for 10% of global energy consumption today, space cooling in 2016 alone was responsible for 1045 metric tons of CO2 emissions. This number is only expected to increase, with the International Energy Agency estimating that cooling will reach 37% of the world’s total energy demand by 2050.
Cracks, which could be classified according to their thickness as fissures or fractures, are serious problems in the construction industry that can negatively affect aesthetics, durability and, most importantly, the structural characteristics of a project. They can happen anywhere, but occur especially in walls, beams, columns, and slabs, and usually, are caused by strains not considered in the design.
ETH Zurich has unveiled details of “Concrete Choreography,” an installation recently inaugurated in Riom, Switzerland. The installation presents the first robotically 3D printed concrete stage, consisting of columns fabricated without formwork, and printed to their full height in 2.5 hours. The process is expected to greatly improve the efficiency of concrete construction while achieving the fabrication of complex components.
Physical models have, for centuries, been a highly-effective way of explaining an architectural idea, allowing the audience to experience a concept in a plan, section, elevation and perspective all at once. However, a model can communicate so much more if you deviate from traditional cardboard materiality. If you want to express the monolithic massing of your latest scheme, or its expressive texture, then a model of plaster or cement may capture so much more than a digital rendering ever could.
Creating a concrete model is profoundly engaging, as it forces us to follow a methodology similar to that of large-scale construction: make a mold / formwork, mix the cement or plaster with water, and then pour. When done correctly, the resulting model could stand as an architectural sculpture in its own right.
Below, we have rounded up concrete models from the ArchDaily archives, giving you the inspiration to set your concrete model ideas in stone.
Matter Design Studio has partnered with CEMEX Global R&D to challenge the relationship between the mass of materials and the physical effort of contemporary construction practices, exploring the movement and assembly of heavy objects on a real scale, manufactured using advanced computing. The objective of Walking Assembly is to eliminate the crane from the constructive equation, transferring the effort from people to objects, freeing them to play with the mass.
Why use concrete in bathrooms?
Béton brut or "raw concrete" is a naturally porous material that provides many advantages for the design and build of a bathroom. As a waterproof and pressure-resistant material, it is easy to clean, doesn't deteriorate, prevents bathroom fungus and is low maintenance. Attractive as it is functional, concrete is versatile for both on-site furniture and wall coatings, floors and even shower trays. In addition, due to its thermal mass, concrete is an excellent material for floor heating.
Pro Tip: There are a variety of concrete finishes, but for the safety of daily bathroom users, you must add a surface sealer and a certain percentage of traction to avoid slippage.
Below, we've compiled 26 concrete bathrooms that find intimacy in béton brut.

Paris La Défense is seeking to vitalise the ‘interstitial volumes’ that lie beneath its central esplanade, interlocked with underground infrastructures. Located at the heart of La Défense, those spaces are very close to public transport and offer high potential due to their distinctive size and morphology. The aim is to use them to develop a new offering of activities accessible to the public – and see a lively and unusual destination emerge as a result. Paris La Défense, as the urban planner, developer and manager of the business district, is launching a competitive dialogue process. The purpose to this process is to award an architectural, programming, engineering and planning services framework agreement for the vitalisation of the central residual volumes. A bonus of 200 000 € will be given to the selected candidates who will complete the procedure.

The idea of turning cold, raw materials into elegant shapes has always fascinated artists, architects, and designers. In the Carrara marble sculptures of Lorenzo Berdini and Michelangelo, human forms were carved from heavy blocks of stones with great detail and precision. There is no difference in architecture: from taking a light volume off the floor, to leaving a small indentation between a structure and a fence, to altering the lining of a block, there are several devices to make buildings visually lighter.
3D printing itself is no longer a new technology, but that hasn’t stopped researchers and innovators around the world from coming up with new applications and opportunities. Some experiments with new materials have been driven by sustainability concerns and others are simply the result of imagination and creativity. Others have chosen to invest their time utilizing more traditional materials in new ways. Materials, however, are just the beginning. Researchers have developed new processes that allow the creation of objects that were previously impossible to print and, on a larger scale, new building typologies are being tested - including a Mars habitat!
The architectural and engineering feats of Spanish architect Santiago Calatrava can be admired around the world, but his City of Arts and Sciences, designed alongside Felix Candela, has remained a modern architectural marvel. Like many international visitors, Lebanese photographer Anthony Saroufim found himself inherently attracted to the highly publicized building complex with a specific, tailored angle - unraveling the relationship between the built reality and the people interacting with it.
Living Architecture has published photographs of the Peter Zumthor-designed “Secular Retreat” as it nears completion in Chivelstone, Devon. The retreat will be the Pritzker Prize-winning architect’s first permanent building in the UK.
The dramatic, layered concrete and glass retreat is the seventh commission in the Living Architecture series, “designed by leading artists and architects in distinctive, unique sites across England.
