At the closure of the war, the school building was restored to the School Committee and the college was re-opened in November 1945. Noble convalesced in London and was temporarily substituted by the senior master Yung Kai-yin. When Noble resumed duty in 1946, the enrolment had increased to such an extent that around 600 students crammed into the building originally designed for 350. The college premises in Bute Street, Mongkok proved to be too small to operate an ideal school. A project for building a new school was therefore contemplated and negotiations resulted in the selling of the existing land and building to the Mongkok Church.
