Kidd House (named after Hubert Kidd, Principal 1943-63) was built in 1981. Volunteer dayboys from Gray and Ogilvie, newcomers with no house affiliations plus a few attached to boarding Houses, moved across. It was built with a flat for the Housemaster which was later converted into an extension for the Bishops Support Unit and is now the Post Matric centre. Kidd House has about 105 dayboys.
