Isleworth Studios were based on Worton Hall, in Isleworth. The house was built in 1783 then rebuilt and extended in the early 19th century.
Film producer George Berthold Samuelson acquired the house, together with a nine-acre estate in 1913.
The ground-floor rooms became dressing rooms, canteen, wardrobe and other offices; the upper rooms became bedrooms for anyone staying overnight.
Filming of Conan Doyle's A Study in Scarlet began in summer 1914, and the studios were officially opened on 1 July that year.
