Sustainable temporary architecture seems like a dichotomy but should be a major concern for the construction industry. Now aware of its impact, architecture must contribute to a more sustainable management of resources and despite their short time frame, ephemeral structures should be no exception to the rule. This work aims to develop a simpler and more accessible computational workflow based on the particle system tool Kangaroo inside Grasshopper to match design intent with available material stock. The proposed research examines the potential of combining raw or reused materials, such as wood and plastic, with easily accessible architectural technologies and tools to generate temporary and sustainable constructions. The workflow allows for many design variations using only simple and intuitive tools in both its digital and physical stages and aims to support the simple development non-standard, responsible temporary architecture that fully implements the principles of a circular economy.
