The built environment is a huge influencer on ‘sustainability’, we spend over 90% of our time working, living and playing within our buildings. Despite sustainability and corporate social responsibility initiatives it is irresponsible that we have generally failed to grasp our influence and to address the potential to move the needle on wider global sustainability and climate issues.

Restorative and regenerative approaches can flip this enabling buildings to become part of climate regeneration solutions. Maybe sustainability is not a journey, but a state of equilibrium, based on giving as much as we take. On the negative side where we take more, we are unsustainable and no matter how much we reduce our impacts we will always remain unsustainable. On the positive side 'to do more good' we open doors to restore environments and
