On The Wing is an architectural, material and environmental design strategy that addresses history, nature and sustainability to create a place that enriches biodiversity and rehabilitates the local environment. The Centre and associated buildings are made from natural, low-maintenance materials with low embodied energy, (clay tiles, timber structure and boarding) using simple repetitive architectural elements overlaid with organic structures, patterns and systems. The buildings reflect two primary influences: traditional Kent barns, and the wings of birds and bats in flight. The overhanging roofs direct rainwater into constructed wetlands, which also purify grey water from the buildings. The cross-laminated timber (CLT) roof structure evokes the construction of local barns, and is designed to harmonise with natural forms. Habitat walls are created in the unglazed sections, using recycled timber from the site.
