We undertook detailed and extensive research into the history and development of Dial House, including discovering the architect’s drawings from the 1920s to show what work had been carried out. This enabled us to engage proactively with the local planning authority’s conservation officer. The location of Dial House, Bourton on the Water, is the classic Cotswolds village and draws tourists from all over the world to see its honey-coloured 17th and 18th buildings. Dial House is a deceptive building; originally constructed in the 16th century, it was extensively altered, extended and apparently re-fronted in 1923. The exact degree to which this early 20th century work had altered the building had, before our involvement, not been well understood, and indeed the list description was particularly inaccurate.
