In advocating the repair and adaptation of existing buildings, Donald Insall Associates has established building conservation as an inherently sustainable approach to architecture, both in terms of retaining the embodied energy of the building as well as stewardship of the historic environment, or its ‘spirit of place’.

Each building is unique, and we do not impose standardised solutions to building conservation and reuse in order to achieve the best results for the building, its inhabitants and our clients. We carefully study each building and diagnose its defects to inform how to reduce the building’s energy consumption, improve the users’ environment, and ensure a sustainable future for the building.

The practice has an active sustainability group, comprising members from all levels within the practice. They meet regularly to encourage sustainable practice, monitor our offices’ energy use and the environmental credentials of our suppliers, and share them with the rest of teams across the country – for example, we only use ‘green’ energy providers across all branches.

We are accredited ISO 14001 Environmental Management Systems with corporate and individual memberships held with The Green Register of Construction Professionals. Our projects have been recognised through a number of sustainability awards for multiple projects, including the Green Apple award.
