Practice
Donald Insall Associates has pioneered a creative approach to managing change in the heritage environment over 65 years. A 140-strong practice of both architects and heritage consultants, we have led nationally significant projects including the revitalisation of Rochdale Town Hall and the decade-long conservation work to Westminster Hall which won the Europa Nostra Award in 2024. We operate across eight studios across the UK: London, Bath, Birmingham, Chester, Conwy, Manchester, Oxford and York.
Our work is underpinned by our specialist expertise. We have comprehensive knowledge of architectural history, conservation, traditional materials, repair technique, and modern standards and technologies.
Our expertise is authoritative and widely respected, including by local authorities, Historic England and other key stakeholders. Our work has been recognised with over 200 awards, including the RIBA, Civic Trust and Europa Nostra conservation awards.
Our values towards people and the planet are reflected in our BCorp certification, ISO 14001 accreditation and employee ownership structure.
