Boronia House, Mosman, Sydney, Former residence and heritage-listed house in Mosman, Sydney, Australia

Boronia House is a two-storey brick residence at 624–632 Military Road, Mosman, set back from the street in an open garden behind a stone fence capped with iron cresting. It faces south and has a substantial two-storey wing at the north-east corner, added probably in the late 1890s, with a glazed bay featuring Art Nouveau detailing in the drawing room.

James and John Kearey, carriage builders from Newtown, built Boronia and its twin Telopea in 1885 as their own homes, sharing a garden and entrance. The 1890s depression forced the sale of their assets, and Boronia was bought in 1896 by money broker George Willis Godwin, whose family kept it for 50 years. Mosman Council acquired it in 1952 and restored it in 1985.

The house is named after a native Australian flowering plant and features a formal Victorian garden with evergreen magnolias and camphor laurel trees framing its gates. This setting reflects 19th-century design principles and creates a sense of heritage within the modern urban surroundings.

The building now operates as a restaurant and event venue following its comprehensive 1985 restoration by Clive Lucas & Partners. The site with its gardens is accessible, though public access may be limited outside of dining or event hours.

The property forms one half of a matched pair of neighboring houses, with its companion building called Telopea sharing a common garden and entrance arrangement. This architectural pairing between the two residences is a distinctive feature from this building period.
