We lifted 20 tonnes of soil on to the green roofs of the Muse with our own hands and the result, photographed last June, only four months after planting, has contributed to National Geographic’s feature promoting the use of green roofs on buildings for environmental and ecological reasons.

Again I give thanks to Dusty Gedge for advising me on soil design and procurement, as well as native wildflower meadow planting and arranging monitoring to measure the growth in biodiversity.
