[3][4] The Edwardian Gothic main wing of Wesley dates from 1917 and was designed by the winner of a competition, Byera Hadley (1872–1937),[5] an English-born architect who had emigrated to Australia in 1887.

[5] The brown face brick and sandstone building originally consisted of the central wing, dining room, chapel and Master's residence.

The interiors are detailed in a neo-Gothic style with polished timber staircases and wainscotting, leadlight windows and quatrefoil plaster ceilings.

Further extensions were added in 1965 when Fowell, Mansfield & Maclurcan increased the capacity of the chapel and in 1969 when the same firm designed the Tutors Wing.
