This visionary design not only respects the historic integrity of the listed building but also fulfills the client’s ambitious goal of becoming the most sustainable school in London. The construction unfolded in harmony with the school’s timetable and a tight schedule, demonstrating ABL3 Architects’ commitment to minimizing disruptions.

To avoid any impact on the listed building, the new structure was ingeniously elevated on stilts, preserving precious playground space. Accessible through a narrow 1.2m side passage, the construction process utilized a crane during school holidays for heavy loads, ensuring a seamless and efficient operation.

From the river’s perspective, a commanding balcony steals the show, aligning perfectly with the water’s edge. The entire composition harmonizes with the idyllic setting, transforming a complex brief into an elegant and inspiring architectural solution.
