Ste Garlick, left, and Chris IredaleThe appointments mark a new approach to the group's leadership, with a dual fractional leadership model designed to ensure both leaders remain actively engaged in professional practice while leading the organisation. Both will continue in their existing professional roles while leading the AECB, ensuring the organisation benefits from leaders who remain actively involved in the day-to-day challenges and opportunities facing the built environment. Garlick joins the AECB from multidisciplinary design practice BDP (Building Design Partnership), where he is the strategic and advisory lead for decarbonisation and retrofit. An experienced architect and sustainability leader, he combines technical expertise with collaborative leadership to help organisations navigate complex sustainability challenges, adapt their buildings and estates, and build organisational resilience. At the AECB, his focus will be on strengthening collaboration across a growing membership, building on the organisation's evidence-based approach to building performance, and broadening its influence across the wider built environment.
