This green roof was planned and built to star as the pilot project of AREA, the African Research & Exchange Academy, the brainchild of Dr. Ajume Wingo, a man dedicated to helping his country and community.

The vernacular architecture of Cameroon tends to look inward to protect against the glaring light, heat, and dust of summer and the relentless, winter winds and rains.

With the indispensable ingenuity of structural engineer Terence Lendzele, Dakin designed the glorified “shed” to wrap itself around volcanic stone. She dug up native grasses, perennials and soil (2-3 inches in depth) and carried it in buckets up to the roof, laying it down exactly as it lived on porous rock nearby.
