Jiri Lev (/ˈjɪrɪ ˈlɛv/, Czech: Jiří Lev) is an Australian building and urban designer, working in the field of sustainable public, residential and disaster-relief development.
Lev's works are known for their prolific use of sustainable, natural or near-raw construction materials and construction methods (Gulgong Holtermann Museum, Courtyard House) such as locally sourced timber, rammed earth, stone, hempcrete, canite or clay and lime renders. He advocates for sustainable, resilient and ethical architecture in his writing, lectures and workshops.
In 2014 Lev founded ArchiCamp, an irregular grassroots gathering of accomplished architects and architecture students, introducing the concept of loosely organised, guerilla style events, focused on learning, networking and invited architectural intervention within disadvantaged or disaster-stricken rural communities.
In response to the 2019–20 Australian bushfire season, Lev established Architects Assist, a “platform for equitable access to sustainable and resilient architecture.” By February 2020 the organisation represented approximately two thousand members, architects and architecture students providing pro bono assistance to the community.
Lev was born in the Czech Republic to parents Jiri Loew, Czech architect and academic and Lydie Loewova, architect. He studied architecture under Richard Leplastrier and Kerry and Lindsay Clare at the University of Newcastle.
