St John Bosco College, South London


Using our expertise in steel structures the Walsh team developed a new purpose built school and two residential blocks in Battersea, London, within a demanding time scale.

This new school structure consisted of a 4-storey block of classrooms and a large sports hall. The residential development adjacent to this contained 102 apartments, including affordable housing for local residents.

This comprehensive task allowed us to demonstrate our capability in a range of steel structures. We created larger classroom sizes by removing the need for internal columns. We achieved this by designing various long span steel frame structures that worked in composite action with precast hollowcore floor units. We also utilised precast floor slabs to reduce the total weight of the structure, reducing foundation costs and giving an overall more sustainable solution compared to a traditional reinforced concrete design. For the two residential blocks, a cross-laminated timber load-bearing wall solution was decided on, supported by a filed raft foundation. The prefabricated wall panels allowed for a fast erection time and sustainable design.

A combined structural and services strategy was developed to reduce the overall building height of the school, reduce costs and achieve planning more quickly. We were proud to successfully complete the project on budget and in time for the start of the academic year.
