The Red House, built in 1844, is located in Port of Spain, bounded on the north by Knox Street, on the south by Hart Street, on the east by Abercromby Street and on the west by St. Vincent Street. It is the seat of Parliament and an iconic building for Trinidad and Tobago. The current structure was built after the original government administration building was destroyed by fire in 1903. The new building was intended to house the Legislative Chamber and the Offices of the Governor, the Attorney General, the Colonial Treasurer, and the Law Courts. The design was revised by public draughtsman Daniel Hahn and it was he who added the high central cupola popularly known as the Rotunda, the ornate stucco ceilings in the southern and northern chambers, and the fortifications around the roof.
The Government of Trinidad and Tobago decided to restore the Red House and establish a distinct Parliamentary district for the permanent occupation of the Parliament. The district will include a Parliamentary Complex for Administrative and Ancillary Services building that will be located to the north of the Red House. These works allowed for the removal of Parliamentary administrative offices from the Red House Parliamentary campus, which provides additional space and also includes a modernised Parliament Library.
