The Prep has an all weather sports pitch, netball court and cricket nets.

The school has two science labs, a design Technology workshop, music hall and ICT suite.

The Vicar of Twickenham, George Glossop and his family, who lived at Amyand House, commissioned the architect, Robert W. Edis, FSA, to build them a new home in the grounds of their house and they moved into the newly-built property in 1871.

From 1888, the original house at 32 Waldegrave Park, on which the existing main school building is based, was known as 'Heriotdene', and became the home of Henry Cheers, a highly successful Victorian and Edwardian architect from Chester, who designed many schools, town halls and libraries across England: among them Hull Northern Library in 1895; the 'Victoria Jubilee Technical School' of Preston, Lancashire, in 1897 (since renamed the 'Harris Building', and now forming the main administrative block of the University of Central Lancashire); Chorley Training College in 1905 (now Chorley Public Library); and town halls from Oswestry and Halifax to Hereford and East Ham.
