Although nearly all of the spaces were structurally altered in one way or another when Hall, Todd, Littlemore, and Farmer took over as the architecture team in 1965, the Reception Hall was the one space that was left largely untouched. After reengaging with the Opera House in 1999, Utzon designed the interior of this hall, which opened and was renamed the Utzon Room in 2004. It is the only interior space of Utzon's design in the entire building. On the wall hangs a 46-foot-long wool and cotton tapestry designed by Utzon. The piece is titled Homage to C. P. E. Bach and was inspired by Bach's Hamburg Symphonies and Raphael's painting Procession to Calvary.
