I wish this was my house but, sadly, it isn’t. It’s Forty Hall, a Grade I listed manor house now owned by the London Borough of Enfield. It was originally built in the early 17th century for Sir Nicholas Rainton, a leading haberdasher who later served as Lord Mayor of London. The house has been a museum since 1951 and recently re-opened following a complete renovation and refurbishment.
I thought it would be interesting to find something about Forty Hall among our records so I decided to look it up in the Valuation Office survey. This survey was carried out in the years leading up to the First World War to assess the base rate for a new property tax called increment value duty, which had been introduced under the Finance (1909-10) Act 1910. Although increment value duty proved controversial and the legislation was repealed in 1920, 1 the surviving records of the survey now have a second ‘life’ in the archives. They are now one of the most popular sources for house history and local history, and are often used by family historians and professional researchers too.
