Knell House is a building exclusively for the Early Years set in its own garden. This creates a very secure environment for the girls to learn and play. The main facilities are:
- Two role play rooms which are frequently re-themed to stimulate the girls' imagination.
- The garden which has a wide variety of outside play equipment
- A dedicated Art room for messier activities
- Nursery and Reception classrooms
- A Hall space for gym, lunchtime and assemblies
In addition the girls visit the Junior School where they use the larger Hall (used for Productions and assemblies), the studio (where weekly ballet classes are held after school) and explore the Eco-Garden.
