The Sage

Sage Gateshead is an international home for music and musical discovery, bringing about a widespread and long-term enrichment of the musical life of the North East of England.

The Sage Gateshead contains three performance spaces; a 1,700-seater, a 450-seater and a smaller rehearsal and performance hall, a Northern Rock Foundation Hall. The rest of the building was designed around these three spaces to allow for maximum attention to detail in their acoustic properties.

Structurally it is three separate buildings, insulated from each to prevent noise and vibration travelling between them. The gaps between them may be seen as one walks around inside. A special 'spongy' concrete mix was used in the construction, with a higher-than-usual air capacity to improve the acoustic. These three buildings are enclosed (but not touched) by the now-famous glass and steel shell. Hall One as intended as an acoustically perfect space, modelled on the reowned Musikverein in Vienna. It's ceiling panels may be raised and lowered  and curtains drawn across the ribbed wooden side walls, changing the sound profile of the room to suit any type of music. Hall Two is a smaller venue, possibly the world's only ten-sided performance space. The building's concourse was designed to be used for informal music-making. Below the concourse level is the Music Education Centre, where workshops, community music courses and day-proofed rooms, one of which is also a recording studio.

The building is open to the public throughout the day. Visitors can see rehearsals, soundchecks and workshops in progress. It has five bars, a brasserie, the "Sir Michael Straker Cafe", and "The Barbour Room" - a multi-purpose function room which holds around 200 people. There was also "ExploreMusic": a technologically well-equipped musical branch of Gateshead public library, stocking books and current magazines covering all aspects of music, a CD library with listening posts, and computers with free internet access, subscriptions to music websites and music software. However this was closed in March 2011 owing to funding cutbacks to Gateshead Council, who funded this particular part of the building.

The fact that the main entrance doors to the western end of the building are still not working properly, seven years after the building's opening, was described as "disappointing" by centre general manager Anthony Sargent in the North Music Trust's 2010-11 annual report. As of February 2012 significant work has begun on improving the entire Western entrance to the building, including brand new disabled and fire access doors and reinforced revolving doors. As of March 2012 this has now been completed.
