Following the development of fabric structures expertise on the projects with Frei Otto, Buro Happold was instrumental in further developing the knowledge and technology of fabric structures. With Bodo Rasch, a protégé of Frei Otto, and drawing on experience from the Pink Floyd canopies, they designed folding, umbrella-like canopies to shade the courtyard of Al-Masjid al-Nabawi (The Mosque of the Prophet) in Medina, Saudi Arabia. They also designed the, at the time, largest fabric canopy in Europe at the Ashford Designer Outlet in the UK.
