Founded in 2001, Trethowan Heritage began as an architectural practice delivering both architectural and heritage projects across Australia.
The practice was recognised in 2015 as a joint recipient of the Victoria Architecture Award for Heritage Architecture, and again in 2023 with the John George Knight Award for Heritage.
A new chapter began in 2025 for the practice with the architectural services concluding and the focus made exclusively on heritage consultancy - continuing our commitment to the historic built environment.
