Laurelbank, Victorian heritage mansion in Willoughby, Australia.

Laurelbank is a Victorian mansion with sandstone foundations and slate roof located on Penshurst Street in Willoughby, New South Wales. The building features decorative iron columns along its verandahs and now serves as a function center while maintaining its original gardens with laurel trees and jacarandas.

The site was part of a 240-hectare grant made to Archbold James Sterling in 1850. Former Auditor General William Lithgow acquired it, and in 1854 Laurel Bank Cottage was built for Mr and Mrs Joseph Griffiths, with stables and market gardens. The Florances bought it in 1924; in 1964 Ku-ring-gai Lodge Pty Ltd acquired it for Masonic meetings.

The name Laurel Bank comes from the row of laurel trees planted along what is now Laurel Street, a boundary still visible on the site. Since 1964 the cottage has served the Ku-ring-gai Lodge, now the Laurelbank Masonic Centre Pty Ltd, which uses it for Masonic meetings and functions.

The building currently operates as a function center, so access may vary depending on scheduled events and private bookings. When visiting, look for the preserved external features and take time to walk through the original garden areas if they are open to the public.

The original stable buildings still stand behind the main house, featuring the same Victorian Italianate details as the mansion itself. These outbuildings reveal how the entire property was designed as a unified architectural composition.
