Sutton High School is an independent day school for girls aged 3–18 in Sutton, Greater London. It is run by the Girls' Day School Trust (GDST). It was founded in 1884 by the then Girls' Public Day School Trust (GPDST), and was a direct grant grammar school (some pupils having their fees paid by the local authority as in a state grammar school) until this system was abolished in 1976. The first headmistress was Miss Margaret Whyte, and there were 80 pupils on the opening day, 17 January 1884. It has been listed in "Top 100 Independent School" Sunday Times Parent Power Guide, November 2011. Buildings The school's accommodation includes a mix of the purpose-built and the converted from a range of periods, and its oldest building predates the school's foundation in 1884. The school opened in a residential property, Park House, in Cheam Road, which was rented by the Girls Day School Company. By 1886 this had been extended on both sides. This group of buildings is still at the core of the school, and the front door forms the basis of the school logo. In the period between the world wars the buildings were extended westward along Cheam Road, and in 1932 Suffolk House was acquired. The assembly hall was built in 1935, linking Suffolk House to the existing buildings. In 1930 Homestead House in the parallel Grove Road was acquired, to be followed by Hayes House and its neighbour, so that the school's grounds extended between the two streets. The Library was built in 1938, to the south of the core, and in 1959 the Lilian Charlesworth Room was added above it, named after Lilian Charlesworth who had been headmistress from 1939. A new science and language block was opened in 1971 and a swimming pool in 1972. In the 1990s a new "Garden Building" was built, and the former Dene Hotel was bought and converted into a sixth form unit. The school opened its new sustainability-built prep building, Fernwood House, and its new MUGA or multi use games area in September 2022.
