The Great Western Building is a building in Mumbai, India.
This large and palatial-looking building has served many uses. It was once the residence of the Governor of Bombay. William Hornby, a former governor who was instrumental in constructing the Hornby Vellard which bunded the breach at Mahalaxmi, lived here for a few years of his term in office. It also served as the Admiralty house, residence of the Commander in Chief of the Indian Fleet from 1770–1795.
Around 1800 it was purchased by the Government and transformed into The Recorders Courthouse until 1878. The original porch was removed when the street was widened. The property was purchased by Rustomjee Jeejeebhoy and then sold to the Sassoon Family.
In 1883 it was sold again and converted into a hotel known as the Great Western Hotel. A new five-storied wing was added in the early 1890s. It was designed by renowned architect S M N Chandabhoy who also designed another smaller three-storied building in the later 1890s.
In time the hotel closed and the rooms have been divided and further subdivided for optimum rental.
