As we move towards an environmental and regenerative paradigm for crafts, with new objectives, methods, and practices, questions arise regarding the aesthetics of these emerging forms. To address this issue, the main author developed a module aimed at exploring furniture design at the intersection of regenerative materials, structures, and aesthetics. In this context, five cases have been selected to frame the quintessential characteristics of these new raw aesthetics. These case studies showcase varying approaches, with some generating new aesthetic qualities by introducing novel processes, while others embrace a strictly analogue approach to highlight literal aesthetics. The resulting aesthetics have been categorised in this paper as Bio-Brutalism. This emerging aesthetics retains the essential elements of traditional Brutalism, such as stripped-down, raw, monolithic appearance, non-treated finished surfaces, and a commitment to preserving design heritage. However, it also diverges in significant ways, with three core elements identified: subtractive locality, time-based dynamic aesthetics, and nature-human hybrid collaborative processes.
