St John’s has been a leading preparatory school for boys in Pinner, Harrow, and Northwood since 1920. Founded by Mr. Claude Norman, the school began in a single classroom at St John’s Church, Pinner. As it grew, it moved to The Briary in Moss Lane, then to Barrow Point House in 1927. A devastating fire in 1930 destroyed the building, but it was rebuilt and remained home to St John’s for the next 40 years.
