The Custom House is a 19th-century B+ listed building located in Belfast, Northern Ireland. Completed in 1857, the building has been used by various governmental departments, including the Belfast Board of Works, the Inland Revenue, and an Income Tax Office.
Designed in 1847 by English architect Charles Lanyon, work on the actual building didn’t begin until some seven years later under construction firm D. & J. Fulton who finished in 1857 at a cost of £30,000.
Throughout the years the building has undergone numerous alterations with the first taking place just a few year after its completion. In 1861 the building’s forecourt was raised to allow greater basement space and a Westward facing entrance was added. Again in 1872 the Southern entrance (then used as a Post Office) was removed and replaced with another Western entrance which was itself removed in 1886. Further changes were again carried out in 1926 when the interior of the central and Southern blocks were removed, a second floor was added above them and the building’s original chimneys and Eastern entrance’s portico were demolished. A new staircase was installed in the Northern block in 1940.
In 2001 under a PFI agreement HMRC transferred ownership of the building to private company Mapeley STEPS Ltd which was contracted to provide accommodation to HMRC up until 2021.
Custom House Square (Stylised as CHSq) is an outdoor music event held in Custom House Square, Belfast. 2017 was the first year of CHSq, but events have been held at this venue before such as the Belsonic music festival back in 2014. The capacity of this event is 5,000.
