Designed by Architect Foster and Partners and Engineer Buro Happold the faceted roof of the Sage Gateshead concert hall changes appearance as it reflects the changeable british weather looking equally alluring on an overcast day or in bright sunlight. The roof of the Sage consists of 3,000 panels made from stainless steel and 250 made of glass. Each stainless steel panel has a linen finish to reduce the glare and is about four metres long and a metre wide. Each panel is solid and designed to prevent noise from heavy rain causing a distraction during concert performances.
