Richard Griffiths will talk about the conservation and design issues raised by two projects that he has undertaken; Sutton House, a Tudor house owned by the National Trust, which he rescued from a derelict condition as a historic house and community and arts venue; and the old Royal London Hospital, where he acted as conservation consultant to AHMM for its conversion to the new Tower Hamlets Town Hall. In each case a forensic analysis of the many historic layers of alteration, the issues faced by the buildings in giving them a viable future, and the resolution of the conflicting requirements of listed building and building control legislation, led to a strong conservation and design response to the challenge of giving them a sustainable future socially, economically and environmentally, for the benefit of the community.
