This early years education building was delivered on a tightly constrained site adjacent to a Grade II listed school in Lambeth. The structural design responds to challenging ground conditions, spatial requirements and heritage constraints while enabling efficient construction on a limited urban plot.

Early design ideas explored a combined CLT folded roof with a steel frame which created efficient spans and minimised material waste. The hybrid system was ideally suited to Modern Methods of Construction (MMC), supporting rapid onsite assembly and reduced disruption to the neighbouring school. Alternative structural frames were researched which included light gauge steel frame and traditional timber and masonry construction, which both had advantages for the build, but ultimately a MMC route would be favoured by the client.

Given restricted access and variable ground conditions, the building is supported on piled foundations, ensuring safe load transfer and mitigating settlement risks close to existing structures. The foundation system also provided the stability necessary for the split-level configuration adopted to maximise usable volume on the compact site.

This split-level arrangement delivers a double height hall at ground level, a mezzanine with a viewing balcony and music room, and spacious upper storey classrooms. The structural grid and load paths were carefully coordinated to maintain openness and flexibility while fitting within the tight footprint.

Externally,the duotone brick façade— red brick below and white glazed brick above— required careful detailing to manage differential movement, support varied window openings and integrate soldier course brickwork. Irregular window geometries introduced localised structural requirements, including bespoke lintel solutions and incorporation of recessed seating.

Sustainability is embedded within the structural strategy. The CLT folded roof provides a low carbon, high performance solution while contributing to the building’s warm interior character. Additional environmental measures include solar shading, natural ventilation, photovoltaics and an air source heat pump.
