Our Philosophy

To unlock the full potential of a building one needs to consider every stage of a project and explore the opportunities that lie between the disciplines.

Sustainable Built Environments (SBE) was formed in 2001 by a multi-disciplinary team of industry professionals passionate about the role that the built environment could have in shaping thriving communities and cities. Over these years our team has delivered an enormous portfolio of work, locally, nationally and internationally.

The founding father and leader of SBE was David Oppenheim, still recognised today as an influential thought leader in the field of ESD and after whom the National Architecture Award for Sustainable Architecture is named. Sadly, David passed away in 2007.

David's holistic and integrated approach to design has become our philosophy. As architects and engineers we understand the importance of inter-disciplinary collaboration to the successful delivery of a performing building. As dedicated ESD consultants our aim is to work with and support design teams to navigate the sustainable building landscape – from meeting Town Planning and statutory energy efficiency requirements through to designing and constructing high performing and innovative buildings, and achieving recognition for best practice and excellence along the way.
