[3][4][a] Construction started with the demolition of everything except the original facade of Newland House in 1926.

[9] The third phase involved inserting an Art Deco staircase into Newland House.

[10] The design for the main building involved a symmetrical main frontage with fifteen bays facing onto Newland with the end bays slighted projected forwards; the central section featured a portico with paired Doric Order columns and balustraded parapet; there were sash windows on the first and second floors with a stone surround which extended to both floors.
