King John's Palace (Colnbrook) Grade II listed structures include four milestones, Beech, Oak and Linden Houses at Upton Hospital, St Ethelbert's Church, Slough and Slough railway station. 1918 saw a large area of agricultural land to the west of Slough developed as an army motor repair depot, used to store and repair huge numbers of motor vehicles coming back from the battlefields of the First World War in Flanders. In April 1920, the Government sold the site and its contents to the Slough Trading Co. Ltd. Repair of ex-army vehicles continued until 1925, when the Slough Trading Company Act was passed allowing the company (renamed Slough Estates Ltd) to establish an industrial estate. Spectacular growth and employment ensued, with Slough attracting workers from many parts of the UK and abroad.

During the Second World War, Slough experienced a series of air raids, mostly in October 1940 (the largest number of people, five, dying as a result of a raid on the 13th), and an emergency hospital treating casualties from London was set up in Slough. Local air raid deaths and deaths at the hospital account for the 23 civilian lives recorded lost in the borough area. After the war, several further large housing developments arose to take large numbers of people migrating from war-damaged London. Between 1955 and 1957 the town was the site of the Slough experiment, a large-scale road safety trial. The old Slough library was opened on 28 November 1974. It was officially called the Robert Taylor Library, named after Alderman Taylor in recognition of his contribution to the library service. The library was officially opened by the Mayor, Councillor DR Peters, on 15 May 1975. It was demolished in May 2017 as part of the programme of redevelopment in the town centre.
