Jorge Drexler sings, in one of his songs, that “we always look at the river, contemplating the other riverbank”. Beyond understanding everything that was done, looking back at the past year can serve to get some clues about the future. This 2021, we published more than 160 articles in the Materials & Products section, covering a wide range of topics. From complex concepts such as 4D printing or very little processed materials such as hempcrete and bamboo, drawing a retrospective of the covered themes and understanding what interested our readers the most is an interesting exercise to foreshadow some trends in the future of the construction field. Looking at our most viewed articles, three large themes are evident: 3D printing, pre-fabrication, and interior renovation. Below, we present a compilation of each topic, reflecting on what we can dare to say about the trends in the construction industry that should consolidate in 2022.
