Being up to date with new technologies, understanding the best solutions for each project, and knowing the products present in the market and those that will be used in the future. We have observed that these themes arouse great interest in the architects, students, and architecture lovers who visit our site every day. In 2019, ArchDaily began to focus more on materials, covering products, construction techniques, and raw materials in general. The year is coming to an end, so we have compiled the most viewed articles on these topics, trying to understand what they imply for the present and where they will take us in the coming years.

At the beginning of 2019, we identified 3D printing as a trend that would influence architecture in 2019. This was not a difficult prediction to make. Aside from noting a 70% increase in reader interest in 3D printing throughout the previous year, we saw how the architectural community has had a long-running engagement with 3D printing, from using the technology to tackle homelessness, to creating affordable yet complex structural connections.

This does not mean that 2019 was a "boring" year in the 3D printing world. In fact, while the influence of the technology in the architecture of 2019 was predictable, the various ways in which this influence manifested was not. Throughout the year, 3D printing seemed to appear everywhere, from spanning a canal to replicating timber, and imagining neighborhoods for Texas and Mars.

When we talk about roofs or fifth facades it is already a classic to think about green roofs. In reality, there is a wide range of uses and possibilities that materialize in different ways depending on the specific technical needs of each roof as well as the spatial and climatic possibilities of each location. The roofs can also be favourable spaces to develop structures, extensions, recreational areas and interactive spaces. It could even play a key role in the integration of a building with the landscape.
