The school is housed for the most part in traditional buildings but enjoys excellent, modern facilities. A major investment programme has produced outstanding accommodation for IT, Music, Technology and Science to add to our existing well-equipped teaching rooms and Library Resource Centre. There are also specialist facilities for Art, Dance and Drama, air-conditioned computer suites, a gymnasium, fitness suite, sports hall, outdoor swimming pool and extensive playing fields.

Testbourne library is a modern e-learning library, using Eclipse.NET. The library has over 5,000 books ranging from Reference, Audio, Fiction and Non-Fiction books as well as popular magazines and newspapers. The library is kept up-to-date, and we try to ensure that all books are no more than 10 years old. The librarian regularly liaises with teachers for book requests.
