The Judges House, Former gentleman's villa in Sydney central business district, Australia

The Judges House is a 19th-century building constructed using traditional colonial methods and materials typical of New South Wales during the British settlement period. The structure displays characteristic architectural features of the era, including solid stonework, timber details, and classical proportions.

William Harper built the house in 1827, most probably to his own design, as a gentleman's villa; it is the oldest building in the City of Sydney area originally built as a private residence. Its name comes from its first tenant, Judge Dowling, not its owner. From the late 19th century it served as a night refuge and soup kitchen for the homeless, through the depressions of the 1890s and 1930s, and was added to the New South Wales State Heritage Register on 2 April 1999.

The name comes from Judge Dowling, the house's first tenant, not its builder William Harper. From the 1890s the villa served as a night refuge and soup kitchen for homeless men, a use tied to the depressions of the 1890s and 1930s. The rear addition at 529 Kent Street housed Suntory Restaurant and later Tetsuya's until June 2024.

The Judges House stands at 531 Kent Street, with the modern addition and former garden sections on the adjoining lot at 529. The property is privately owned and divided into separate lots, so the house itself is not open to the public; the restaurant occupies the rear addition rather than the 1827 villa. Visitors see the exterior from Kent Street in the Sydney central business district.

The house's name comes not from its builder but from its first tenant, Judge Dowling, whose legal association outlasted the fortunes of surveyor William Harper, the man who built it in 1827. Harper's career declined as a paralytic condition affected his right hand, reducing his capacity for field work and mapping.
