Castle Hill School

We are thrilled to be designing and building Castle Hill School’s new straw bale classroom.

The new Castle Hill School building will be a sustainable and fun learning environment for its pupils. Straw, stone, lime, earth, and wood are the main building materials. These natural materials have been carefully chosen to create a comfortable, super insulated healthy space ideal for young people to explore ideas.

About the new classroom

The straw bale classroom will be used to host pre and after school clubs, for cooking classes and as a library and informal ICT suite. It will be an adaptable space that can be changed to suit the needs of the group. Straw and clay will be used to create soft reading nooks for informal learning.

The outside is as important as the inside for learning opportunities. The new building will incorporate changes to the playground area creating more Incredible Edible beds, a veranda for covered outdoor playing and a green roof will increase the habitat space for birds and wildlife. The building will be clad with larch which we are hoping will be sourced from Hardcastle Crags by local company Black Bark and lime render will provide weather proofing for the straw bale walls.

This super energy efficient building will maximise the warmth from the sun from glazing to the south side. Calculations show that only minimal heating will be required to provide optimal temperatures once the heat from the pupils is taken into account. Straw bales provide excellent insulation properties and the internal cob walls will hold the heat from the sun and act like a radiator.
