The largest house in the boarding family, Weaponness is the co-ed Sixth Form house providing room to 60 students. Weaponness was fully renovated and extended in 2021 and is one of the most striking and modern boarding houses in England. The renovation project also won several awards.

As a co-ed house, Weaponness has a large open-plan kitchen and lounge giving access to both girls and boys. In addition to this, single-sex lounges can be found on both the boys’ and girls’ wing. Both lounges have a small kitchenette. In the larger co-ed lounge, students can enjoy a game of pool, table football or any of the board games provided.
