“The 1000-capacity auditorium will have a rooftop dome, glass-covered walkway and outdoor terraces, under Sir David Chipperfield’s vision for the £45m IMPACT Centre, which could open by 2021. The complex, which will provide a long-awaited home for the Scottish Chamber Orchestra, is also expected to become a major new Edinburgh International Festival venue.” The IMPACT Centre “is expected to be open every day, attract more than 250,000 visitors each year and generate £25 million for the economy.”
