The architect, William H. Clayton, was the first and only Government architect, though his choice of Gothic architecture for the building remains a mystery, likely intended to convey respectability and moral authority.

The construction of the Custom House began in 1869 and was completed in 1870 as the residence of H.M. Collector of Customs. The first residents, Edward Binney Laing, his wife Zenobia, and their children, planted the Moreton Bay Fig tree in the front garden. During this time of prosperity, Mr. Laing managed overseas shipping and even acted as Postmaster when the position became vacant. After 15 years of service, Mr. Laing retired and was honored with an illuminated address signed by 49 notable county figures and a purse of sovereigns.

Benjamin Bailey succeeded Mr. Laing as Customs Officer, but in 1890, the Customs office was closed due to reduced shipping activity and merged with the Harbormaster’s duties. The Custom House was left vacant, later rented to tenants for 5 shillings a week, and eventually repurposed by the Police Department to serve as a new Police Station.

In a repeat of history, the aging Police Station on the Strand, next to the Public Library, was abandoned in favor of the former Custom House, which has remained the Police Station ever since. In 1931, the building survived a fire at the original Gables next door, though the south wall was so severely scorched that paint wouldn’t adhere for years.
