Since it first opened over 40 years ago, HCCS's pupil population has grown, leading to expansion of the school buildings. In the last five years, a new Arts building was opened, as was an extension to the science department, and a complete refurbishment of all the science rooms was completed during the summer of 2007. Partially funded by donations and sponsorship from parents and local businesses, the Arts building is home to the art and music faculties, along with a number of rooms dedicated to Sixth Form use on the first floor including a common room, and other 'A level only' courses such as sociology and photography.
In September 2006 a new dining hall facility was completed. This building helped to resolve the problem of over-crowding at lunchtime, allowing lunch to be served in two sittings, rather than four. It also houses a dedicated 'bistro' for the use of Sixth Form pupils, which currently provides food in the mornings, which ends after lunch.
In 2013, the sixth form/arts block was redeveloped, also expanding the sixth form building. Temporary buildings were installed on the site for use as teaching facilities for the 6th form during the building period due to the structural defects discovered in the original facility.[3]
In 2016, the Arts building was demolished and has been replaced with a building which has its own theatre. The sixth form is also in this building, with teaching rooms, a common room and a quiet study area. It also has its own cafe which is only for students in year 12 and 13, as well as teachers.
