Designed by Canadian-born, Boston-trained architect, John Horbury Hunt (1838–1904), Trevenna was originally the home of the Wrights, a prominent New England family of graziers.
Some of the trees in its garden, including horse chestnuts, pines and planes, date back to the 1890s when Trevenna was built.
A sunken garden, complete with stone sundial and fish pond, is on one side of the house, while on the other a series of hedges encloses a private lawn.
They also include a herb garden and orchard and numerous dry-stone walls, some of which have been overplanted with ivy hedges.
The front garden slopes away into a series of hedges and wide perennial borders lead the eye across the Bellevue area of the University with the city of Armidale and Mount Duval in the distance.
