The Hotel Stellar is located on the corner of Wentworth Avenue and Wemyss Lane, in the inner city suburb of Surry Hills. This heritage listed building began as a four storey warehouse designed by Robertson Marks Architects and built in the Federation architectural style in 1918. Three new floors were added in 1925 when it was named Roylt House. It was predominately used by the garment industry until 1972 when it ws partly renovated to suit Stellar Mining, a sapphire mining and polishing business. In 1980, it was remodelled to an inner city residential serviced apartment development known as Stellar House. It was repainted in the historic 1925 heritage colour and renovated in 2013 to it's present 4-star level of hotel accommodation.
