grey water purification system, return of storm water to the wetland system, and energy efficient glazing and solar shading on the façade. Wherever possible, natural light to the internal spaces has been maximised, with large full height and clerestory windows throughout, with the exception of certain galleries, further reducing energy requirements. Materials The material palette is raw and honest, primarily pre-cast concrete, natural timber, granite and 38 glass. These materials provide contrast with the natural landscape, and take inspiration from the work of Tadao Ando. The clerestory windows allow the roof to float above the heavy walls, like the lid of a box concealing treasures within and allowing soft indirect natural light to penetrate the interior spaces. Externally, the precast concrete is finished with a chamfered tartan grid, which draws the eye upwards and lengthways, and emphasises the scale of the building. Internally timber panelling is used to bring warmth to the spaces. The Norval Foundation
