By the time you arrive at the Windsor, a long-awaited, controversial A$300-million redevelopment and restoration of one of Australia’s grandest and most historic hotels will possibly be underway. Or not . . . depending on the progress of the applications, objections, and appeals that have been raging for several years now. The Windsor opened in 1883, an upper-crust establishment that has oozed sophistication and hosted the rich, famous, and glamorous. The hotel holds a special place in Australia’s history as the setting for the drafting of the country’s Constitution in 1898. The planned facelift, expected to take 2 years (once it starts), will add a 26-story tower (and 152 guest rooms) behind the heritage building. But some things won’t ever change: The renowned “high tea” will continue to be served each afternoon, as it has been for 130 years. Many guest bedrooms have striking views of Parliament House and the Treasury Gardens.
