(completed in 1876) at the rear of the building. The East Block (completed in 1866) and the West Block (completed in 1865) house the offices of ministers and senators, as well as meeting rooms and other administrative spaces.

The unifying style of the three structures is Gothic Revival, although the Center Block is a more modern Gothic Revival, while the older East and West Blocks are High Victorian Gothic.

The forms were the same, but their arrangement was singularly modern. The Parliament Buildings also departed from medieval models by integrating a variety of periods and styles of Gothic architecture, including elements from Britain, France, the Netherlands and Italy, all in three buildings.
