John M Headrick & Co Building, Heritage warehouse in East Street, Rockhampton, Australia.

The John M Headrick & Co Building is a brick structure with a rendered facade divided into three distinct sections with varied window bays. Classical architectural details decorate the front, giving it the appearance of a substantial mercantile storehouse from the Victorian era.

The first two-storey brick-and-render section was built in 1894–95 to house the offices and stores of JM Headrick & Co, founded in 1884 by John Mackay Headrick Jnr and Andrew Newton. It was the first Rockhampton commission of architect Alfred Mowbray Hutton, with Holmes & Henrickson as contractors. In 1911 Edwin Morton Hockings extended it, nearly trebling its East Street frontage while carrying through the earlier classical motifs.

The building shows how merchants organized their trade and storage in the late 1800s. Its location on Rockhampton's main business street reveals where the city's commercial center once thrived.

The building is located at 187 East Street in Rockhampton's business district and is easy to find on foot. Nearby landmarks, including the Walter Reid Community Arts Centre, help with navigation and exploring the surrounding historic area.

The three land parcels beneath the building were bought by John Mackay Headrick Snr in 1883, and title passed to his wife after his death in 1884; the company only gained title in 1926. The 1894-95 warehouse was the first Rockhampton commission of architect Alfred Mowbray Hutton, who died in July 1911, the same year Edwin Morton Hockings extended the building.
