By 1900, the accommodation was already proving too small, and in 1914 it was decided to build a new wing enclosing the West Quadrangle, providing additional rooms and a chapel.

[2] John James Burnet was commissioned to draw up plans for the extension, and construction began in August 1914 but was halted by World War I.

[2][3][4] The inside was fitted with wooden stalls and carvings by Archibald Dawson, and a series of ten stained glass windows, designed and made by Douglas Strachan and representing the entirety of human life as a spiritual enterprise, was installed in 1931.

[7] After World War I, it was decided that the new chapel should be dedicated to the memory of those seven hundred and fifty-five men connected with the university who had died in the conflict.

[12] The organist is Kevin Bowyer,[13] an acclaimed performer and prolific recorder, who is artistic director of the Glasgow International Organ Festival, which is held in the chapel and has been running annually since June 2006.

[16] The director of chapel music is Katy Lavinia Cooper, who was appointed in April 2015 after James Grossmith left to become chorusmaster of the Royal Swedish Opera.
