The Abbey is an historic house located at 272 Johnston Street in the Sydney suburb of Annandale, New South Wales, Australia.

The Abbey was the most outstanding of these homes, an "imaginative, romantic house loosely modelled on a Scottish manor".

The Abbey was occupied by housekeepers while Young lived in a house called Kentville, near Rozelle Bay, since demolished.

As part of the bohemian Sydney Push scene, Geoffrey Davis "frequently hosted wild parties in the 1960s and '70s" [6] in the 50-room mansion.

He continued to lease out some of the original separate units for two decades while proceeding with a long-term restoration of the house.

In early 1983, the novelist Christina Stead lived in the house during her last months, cared for by Dr Davis's wife.

[5] Michael Hogan and Ann Sherry restored the house over four years to 2015,[12] working with heritage architect Alan Croker.
