International House, Sydney, Heritage commercial building in Sydney central business district, Australia

International House is a ten-storey commercial building on the corner of York and Barrack Streets, designed by Robertson & Marks in the Federation Free Classical style and built in 1913 by Howie, Brown & Moffat. Its facade combines motifs from different countries and periods, and an external steel fire-escape was added in 1931.

The building was designed by Robertson & Marks and constructed in 1913 by the firm Howie, Brown & Moffat. The site had previously served military purposes before being redeveloped for this commercial venture.

The name Pomeroy House honoured merchant Jeremiah Brice Rundle, who died in 1893 at his residence "Pomeroy" in Potts Point; his estate's trustees built the warehouse as a business proposition. By the 1930s the building held forty offices, some firms taking a whole floor while others shared space between eight and ten agents.

The building sits on York Street in Sydney's central business district with easy access to public transportation. The surrounding area is densely built with other office buildings, making it straightforward to locate and walk to from nearby transit stops.

The building's name changed with its owners: it was Pomeroy House, honouring merchant Jeremiah Brice Rundle's Potts Point residence, until the National Cash Register Company bought it in 1942; by the 1960s it was generally called International House. A 1931 external steel fire-escape was added in the light area.
