Sir Donald Insall: Conservation Architect Dies at 100 2026

Sir Donald Insall, the renowned conservation architect who led the restoration of Windsor Castle after the devastating 1992 fire, has died at the age of 100. His death marks the end of a remarkable career dedicated to preserving Britain's architectural heritage.

Insall was known for his meticulous approach to conservation, distinguishing it from mere preservation. He famously said, "Preservation is what you do for marmalade," emphasizing that historic buildings should be revived and given new purposes rather than simply frozen in time.

Early Life and Career

Born in 1926, Insall studied architecture and quickly developed a passion for historic buildings. He founded his own practice, Donald Insall Associates, which became one of the leading conservation architecture firms in the UK. His early work included the restoration of Kedleston Hall in Derbyshire, Robert Adam's Palladian masterpiece, which he described as "our first big job."

Insall's reputation grew as he took on increasingly prestigious projects, always advocating for a thoughtful approach that balanced historical accuracy with modern needs.

Windsor Castle Restoration

The 1992 fire at Windsor Castle, which broke out on the Queen's 45th wedding anniversary, was a national disaster. Insall was appointed to lead the restoration, a task that required both sensitivity and innovation. The fire had destroyed large sections of the castle, including the historic State Dining Room and St George's Hall.

Insall's team employed a range of strategies, from complete restoration to renewal in spirit. He told Country Life in 2018: "As well as keeping things as they were, or putting them back as one thinks they were – which is chancy and not the main aim – we had to find new solutions to parts that had been irreparably destroyed." The restoration was completed in 1997 and was widely praised for its craftsmanship and respect for the original design.

Other Notable Projects

Beyond Windsor Castle, Insall worked on numerous high-profile projects. He renovated Kelmscott Manor, the Oxfordshire home of William Morris, after it was acquired by the Society of Antiquaries in 1961. He also restored Kedleston Hall and worked on many other historic buildings across the UK.

His approach often involved marshalling teams of architects, craftsmen, and builders to ensure that every detail was handled with care. He believed that conservation was not just about maintaining the status quo but about finding new ways to keep historic buildings relevant.

Legacy and Impact

Insall's influence extends beyond his own projects. He trained a generation of conservation architects and was a vocal advocate for heritage protection. His writings and lectures emphasized the importance of understanding a building's history before making changes.

He received numerous awards and honors, including a knighthood in 1997 for services to conservation. His practice, Donald Insall Associates, continues to thrive and is involved in major restoration projects.
