This 1FE school expansion project for Smitham Primary School, Coulsdon, included the provision of a new build classroom block, refurbishment of teaching accommodation and site-wide landscaping.

The structural frame solution for the new build classroom block uses a combination of cross-laminated timber for the floors, roof, external and internal load bearing walls along with steel beams and columns where structural framing elements are required in order to suit the architectural space planning.

A raft foundation was favoured instead of strip foundations to provide a more cost effective solution.

Lyons O’Neill have also designed a new infiltration system to discharge the additional surface water run-off generated from the additional impermeable area from the site to the water table.
