Donald Insall Associates

Donald Insall Associates is a practice of conservation architects and heritage consultants working across the historic environment. Its services cover conservation architecture, heritage consultancy, new design within historic settings and townscape advice. The firm’s approach rests on researching a building’s materials, construction, history and use before deciding how it should be repaired or adapted. Clients include custodians of significant historic buildings, commercial developers, preservation trusts seeking National Lottery Heritage Fund support, country estate owners and local authorities. Recent projects include the John Rylands Library in Manchester, the restoration of the Camellia House at Wentworth Woodhouse, the conversion of the Old War Office, a reordering of Chester Cathedral’s west end and a long-running conservation programme at Westminster Hall. The practice is listed in London.
