Completed in  two phases from 2004 – 2016, the SciTec facility hosts world class laboratories in the Stringer Biology Department, as well as advanced, industry-standard technologies in the Patrick Engineering Centre. The development was made possible by nearly £8m in donations from OOs, parents, and supporters, in addition to support from the Grocers' Company and other institutional funders.

J M Mills Pavilion

The J M Mills Pavilion commemorates Mike Mills' astonishing 80 year involvement with the School, and was the flagship of the first phase of the Sports MasterPlan. It boasts four changing rooms, a dedicated scorebox, umpires’ facilities and a unique triangular tea-room and balcony with a view across the Main to St Peter’s Church spire. It was generously supported by over 100 cricketing OOs and many parents.

The Adamson Centre for Modern Languages

Occupying the former mathematics and science building opposite SciTec, the Adamson Centre was made possible by the legacy of Fred Adamson (D 37) and by other donations, including a Sony language laboratory. A beautiful, modern refurbishment meets the vernacular architecture seamlessly, and provides a stimulating environment for the study of Oundle’s broad range of modern languages.

The Cripps Library

Completely refurbished in 2011 thanks to over £500,000 in donations, the Cripps Library provides a welcoming and studious environment for individual pupils and classes. Its collection comprises over 24,000 books, alongside rooms for group study and presentations in the Dudley Heesom and Peter Ling Rooms, as well as the Clive Jacques Rare Book Room.
