This expansion, designed in a similar style by Buchanan & McKay, Architects, and built by Peter Doulan, was named "Coronation Hall" to commemorate the coronation of George V and opened on 8 July 1911. Following incorporation, the council area developed a strong industrial character similar to its northern neighbours of Alexandria, Waterloo and St Peters. A "Sydney Morning Herald" profile of the council in 1914 expressed this change: "During the first year of its existence, the council had less than £1000 to work upon. This year the revenue will reach £6000. The district now carries a population of 8500, which is housed in 1750 buildings. Like its neighbour, Botany, Mascot has developed into an industrial centre, and in this respect is making splendid progress. In fact, the whole district will in time become the Birmingham of Australia." With these changes in the local area, the "North Botany" name of the council however raised negative connotations and it was felt in council that it was too similar in name to their southern neighbour; As a result, in early 1911, council conducted a referendum of ratepayers to decide on a new name, with "Ascot" being chosen, which referenced the nearby racecourse. However, when council submitted this request to the state Minister for Public Works, Arthur Griffith, and the Commonwealth Postmaster General, Josiah Thomas, it was rejected based on the view that "Ascot" was a term already well-used for place names. Council then debated on several other options, including "Boronia" and "Booralee", before "Mascot" was chosen, accepted and proclaimed on 31 October 1911. The council established a reputation for its probity and prudent financial management, at a time when the small Sydney municipalities were often struggling to keep up with infrastructure demands, population growth and political infighting. The "Construction and Local Government Journal" praised Mascot council in this vein in a March 1920 editorial, noting "Mascot is essentially a working man's suburb, but the fashionable socialism of Labor Government does not appear to find favor with the sturdy, thrifty working men and intelligent women who have votes in this Municipality, and the reason is not very far to seek, for it is a remarkable circumstance that nearly all the residents own their own homes." At the same time, planning had begun for the construction of a larger public airfield at Mascot, with the Commonwealth Government purchasing 65 hectares for this purpose in 1921.
