Whilst working on proposals for a new science block development, the practice were asked to review possible locations for a new expressive arts space, within the existing school , which occupies the site of the original manor house, Thornton Hall, on the banks of the River Ouse. The only area meeting the space requirements of the brief was an “L” courtyard within the heart of the school, that housed a collection of poorly maintained lean-to buildings. The solution was a modern insertion that was entirely top-lit and naturally ventilated via a series of lantern lights, punched into the roof structure. Key to the success of the space was maintaining natural light to the surrounding stained glass windows. Areas of existing brickwork and stone mouldings remained exposed as reminders of the historic fabric beyond.
