The Abbey is a heritage home at 272 Johnston Street in the suburb of Annandale, Sydney, Australia. It is listed on the Register of the National Estate and the New South Wales Heritage Register. It is also listed by the National Trust.
The Abbey was built by John Young, a builder who had migrated from England to Australia. After working for some time as a builder in Melbourne, Young moved to Sydney and continued a successful career. In 1877, he bought land in what is now the suburb of Annandale, where he had visions of creating a garden suburb that would rival exclusive harbourside suburbs like Darling Point. He proceeded to build an extraordinary group of eight homes along a ridge near Rozelle Bay: The Abbey, Oybin, Kenilworth, Rozelle (now demolished), Greba, Hockindon, Highroyd and Claremont (now demolished).
The Abbey was the most outstanding of these homes, an "imaginative, romantic house loosely modelled on a Scottish manor". It was designed in a variation of the Victorian Free Gothic style and incorporated stencil work, hand-painted panels, timber architraves, a Gothic vault and a tower with gargoyles. (Young was the principal builder of St Mary's Cathedral, Sydney, and it was rumoured that he had stolen gargoyles from the cathedral to use on his Annandale homes.) He also used reinforced concrete, which was quite an innovation in those days. Since Young was a Freemason, the house was decorated with Masonic symbols. It was completed in 1882.
Young built the home to impress his wife and encourage her to return from the UK. She did not return and they never lived in it. The Abbey was occupied by housekeepers while Young lived in a house called Kentville, near Rozelle Bay, which has since been demolished. From 1887, the ballroom and stables of The Abbey were used as a boarding house for private schools.
