The Victorian estate located in the north Sydney suburb of Willoughby was originally built in 1880, and retains a lot of the home’s original period features. As well as the iconic sandstone facade, the elegant property, dubbed Tyneside, also offers high ceilings, wrought iron lacework, and ornate ceiling mouldings on the upper level. The home’s striking exterior is distinguished by its prominent balcony, decorative balustrades, and tiled patio.

The seamless blending of old and new is apparent throughout the home. For example, of the home’s four fireplaces, two remain original wood-burning fireplaces, while the other two have been renovated into gas heaters.

The property boasts five bedrooms and two bathrooms, plus an additional self-contained guest studio. Multiple living and dining areas exist inside and out, including a formal dining room (complete with a bar), an upper-level rumpus room and an attic.
