Originally presented at the 18th International Architecture Exhibition of La Biennale di Venezia 2023, One Hundred and Fifty Thousand Trees explores the lifecycle of timber architecture through the lens of Sara Kulturhus in Skellefteå, Sweden. The installation examines the building’s construction, material supply chains, and the ecological impact on the forests from which its timber was sourced. By asking whether a balance can be struck between using forests as a resource and preserving fragile ecosystems, the project provokes critical dialogue on sustainability in contemporary architecture.
