Work began on the Science Building (the School's eighth building) in August 1987 by builders Paynter Dixon and Architect Butler & Sky led by Mr Maurice Beavington. Mr David Price (former Head of Sciences) was central to the planning and lay-out of the building, this included;
- 2 levels with 6 well-equipped laboratories.
- Staff work rooms and preparation areas
- Chemicals and equipment storage space
- Students' club room and a Common Room for all school staff.
It was completed in April 1988 and refurbished in 2006 to become a Junior School Building for Years 5 & 6. It is now known as JS4 housing Years 4 & 5.
